RELATED APPLICATIONS

The present application is National Phase of International Application No. PCT/JP2011/079486 filed Dec. 20, 2011, and claims priority from Japanese Application No. 2010-283832, filed Dec. 20, 2010.

TECHNICAL FIELD

The present invention relates to a carbon dioxide gas mist pressure bath apparatus for preventing, improving or curing a ischemic heart disease (for example, arteriosclerosis obliterans or ischemic disease) by contacting carbon dioxide to the skin and mucous membrane of a living organism directly or through clothing under a predetermined condition, thereby to improve or promote circulation of the blood in the ischemic region.

Since carbon dioxide (carbonic acid anhydride: CO₂) has properties of being not only soluble in water (water-soluble) but also soluble in fat (fat-soluble) together, and therefore it has conventionally been known that, if carbon dioxide contacts the skin and mucous membrane of the living organism having both properties of water and fat, carbon dioxide penetrates under a subcutaneous layer and it expands blood vessels around the parts of penetrated carbon dioxide, and works to improve the blood circulation.

Further, if penetrating subcutaneously, carbon dioxide has possibilities of displaying various physiological effects such as expanding the blood vessels, accelerating the blood circulation, dropping blood pressure, improving metabolism or accelerating to remove pain substance or waste products. In addition, it has also anti-inflammation and anti-bacterial. Therefore, carbon dioxide has recently been given attentions also from viewpoints of improving health or beauty other than the purpose of medical cares.

In the organization of the living organism, carbon dioxide works to release oxygen having been carried in combination with hemoglobin in a red blood cell. Around parts at the high concentration of carbon dioxide, the red blood cell releases more oxygen. Thus, supply of oxygen to cells by the red blood cell is mainly controlled by carbon dioxide. In short, being without carbon dioxide, hemoglobin remains as having been combined with oxygen and the cell becomes unable to receive oxygen. Carbon dioxide serves to play in fact very important roles also in metabolism within the living organism. Thus, carbon dioxide is not mere waste products resulted from energy action of the cell, and it has gradually cleared that carbon dioxide exerts various important services in the living organism.

Then, for causing carbon dioxide to be absorbed directly in the skin and mucous membrane of the living organism, various apparatuses have been proposed such as utilization of bath agents for generating carbon dioxide in a hot water of a bathtub (for example, refer to patent documents 1 to 3).

SUMMARY OF THE INVENTION
Problems that the Invention is to Solve

In view of various known physiological actions in the living organism as above mentioned of carbon dioxide, in particular, blood circulation effects, blood vessel expansion effects or hyper metabolism effects, an inventor of this invention considered that in case continuously contacting carbon dioxide to the living organism, this action would be effective in improvement or acceleration of blood circulation in an ischemic region. That is, carbon dioxide penetrating under the skin is taken into a tissue (muscle) or the blood.

Blood much containing carbon dioxide is recognized as a condition of so-called “oxygen deficiency”, and it expands the blood vessels, accelerates to increase blood flow, and at the same time, it accelerates a new angiogenesis (arterialization) in the ischemic region. It uses CO₂to accelerate metabolism and supports the arterialization.

As a result of the inventor's various experiments, it has been found that, only by contacting carbon dioxide to the skin and mucous membrane of the living organism, the concentration of carbon dioxide taken into blood was low. Then, the inventor has discovered that, for taking carbon dioxide efficiently into blood, carbon dioxide is changed into the form of a mist, that is, such a condition is prepared that carbon dioxide is shut into bubbles of a thin skin of liquid (called it as “carbon dioxide gas mist” in this invention), and predetermined pressure (higher than internal pressure of the living organism) is added to contact the skin and mucous membrane of the living organism, so that concentration of carbon dioxide taken in blood is heightened, an ischemic region is improved.

By the way, prevention, improvement or curing referred herein also include the ischemic region after surgical operations or embedding of artificial organ.

Means of Solving the Problems

Thus, the present invention is a carbon dioxide gas mist pressure bath method, in which circulation of the blood in an ischemic region can be improved or promoted by contacting carbon dioxide to the skin and mucous membrane of the living organism through either direct contact or contact through clothing, and furthermore ischemic disease in a living organism can be prevented, improved or cured. The following steps (a) to (d) are continued at least once per day for four weeks, that is, a step (a) of producing a carbon dioxide gas mist by pulverizing and dissolving carbon dioxide gas into a liquid, and forming this liquid into a mist; a step (b) of spraying the carbon dioxide gas mist into a carbon dioxide gas mist-enclosing means for enclosing the living organism under an air tight condition, a step (c) of expelling gas existing in the carbon dioxide gas mist-enclosing means into the outside, if necessary in parallel with the step (b), in order to maintain the pressure of gas within the carbon dioxide gas mist-enclosing means at or above a prescribed value being higher than the atmospheric pressure, and a step (d) of continuing such a step of supplying, for at least 20 minutes, the carbon dioxide mist into the carbon dioxide gas mist-enclosing means.

By the way, the invention calls it as “pulverizing and dissolving” to pulverize the liquid into fine liquid drops, and cause to contact and mix with gas (carbon dioxide).

In the meantime, the step (d) is characterized in that while measuring the concentration of carbon dioxide gas mist existing in the carbon dioxide gas mist-enclosing means, the carbon dioxide gas mist continues to supply the carbon dioxide gas mist for at least 20 minutes.

Further, the step (d) is characterized by controlling the supply amount of the carbon dioxide gas mist such that air pressure within the carbon dioxide gas mist-enclosing means is at a predetermined value.

The carbon dioxide gas mist is characterized by containing such carbon dioxide gas mist of not more than 10 μm in diameter. In addition, air pressure within the carbon dioxide gas mist-enclosing means in the step (c) is characterized by being 1.01 to 2.5 air pressure. The concentration of the carbon dioxide gas mist within the carbon dioxide gas mist-enclosing means in the step (d) is characterized by being 60% or more.

Further, the present invention relates to a carbon dioxide gas mist pressure bath apparatus for preventing, improving or curing ischemic disease of the living organism by contacting the carbon dioxide gas mist to the skin and mucous membrane of the living organism directly or through clothing, thereby to improve or promote circulation of the blood, characterized by furnishing a carbon dioxide gas mist enclosing-means for enclosing the living organism under a sealing condition; a carbon dioxide gas mist generating and supplying means for pulverizing and dissolving carbon dioxide into a liquid, generating a carbon dioxide gas under a mist state, and supplying the carbon dioxide gas mist into the carbon dioxide gas mist-enclosing means; an exhausting means for exhausting outside gas in the carbon dioxide gas mist-enclosing means; and a control device for, while exhausting outside gas in the carbon dioxide gas mist-enclosing means, controlling, if necessary, the supplying amount of the carbon dioxide gas mist from the carbon dioxide gas mist generating and supplying means, such that air pressure within the carbon dioxide gas mist enclosing means is set within a predetermined range.

Herein, the carbon dioxide gas mist pressure bath apparatus is characterized by further providing a concentration detecting means for measuring the concentration of the carbon dioxide gas mist in the carbon dioxide gas mist-enclosing means, and the control means controls the supply amount of the carbon dioxide gas mist such that the concentration of the carbon dioxide gas mist is at a predetermined value or more. In addition, an air pressure detecting means is further provided for measuring air pressure in the carbon dioxide gas mist-enclosing means, and the control means is characterized by controlling the supply amount of the carbon dioxide gas mist such that the concentration of the carbon dioxide gas mist is at a predetermined value or more.

The carbon dioxide gas mist-enclosing means is a foldable cover type, a bag type or a fixedly stationary box type which are formed with a space for sealing therein the carbon dioxide gas mist. Herein, the carbon dioxide gas mist-enclosing means is characterized by furnishing a carbon dioxide gas mist inlet port having inside a check valve, an outlet port of discharging an inside gas, a doorway for getting in and out the living body, and an open for exposing the head of the living body. The open has a leakage prevention means for the carbon dioxide gas mist leaking from a space between the open and the living body.

Effects of the Invention

As will be explained in detail, the invention obtained test results of various animal tests concerning improvement or acceleration of the blood circulation in the ischemic region, and contacted the carbon dioxide gas mist of concentration being not less than a predetermined value to the skin and mucous membrane of the living organism for more than a predetermined period, so that improvement or acceleration of blood circulation in the ischemic region has been recognized. Further, by treatment of the invention, it has been confirmed that nitrate ion in blood (NO₃⁻) increases significantly. That is, NO₃⁻ is a comparatively stable oxidation metabolism derived from NO (nitrogen monoxide) being an entity of relaxation factor EDRF derived from endothelial cell in blood, and since NO is discharged from an endothelial cell of blood vessel, a blood flow improving effect by the carbon dioxide gas mist treatment of high concentration (80 to 100%) or the heart re-modeling depression effect has been distinctly suggested in that the endothelial function of blood vessel takes part in.

Many results of animal tests concerning improvements or acceleration of conditions of blood circulation in the ischemic region of the living organism described in the specification of this invention are concerned mainly with wistar rats aged of 8 weeks, and can be applied to human bodies and the living organisms of other mammalian as evidently from correlation with many other experimental examples and clinical data.

EMBODIMENTS FOR PRACTICING THE INVENTION

In the following description, explanations will be made to the embodiments of this invention, referring to the attached drawings.

At first, explanation will be made to the carbon dioxide gas mist pressure bath method for improving or promoting blood circulation in the ischemic region by contacting the carbon dioxide gas mist directly or through clothing to the skin and mucous membrane of the living organism.

FIG. 1 shows a process flow of the carbon dioxide gas mist pressure bath method for improving or promoting blood circulation in an ischemic region. As shown in (A) part of FIG. 1, by use of a carbon dioxide gas mist generating and supplying apparatus which will be explained in detail later (FIGS. 2 and 5), this invention is to provide a carbon dioxide gas mist pressure bath method having a step (a) of producing a carbon dioxide gas mist by pulverizing and dissolving carbon dioxide gas into a liquid, and forming this liquid into a mist; a step (b) of spraying the carbon dioxide gas mist into a carbon dioxide gas mist-enclosing means for enclosing the living organism under an air tight condition, a step (c) of expelling gas existing in the carbon dioxide gas mist-enclosing means into the outside, if necessary in parallel with the step (b), in order to maintain the pressure of gas within the carbon dioxide gas mist-enclosing means at or above a prescribed value being higher than the atmospheric pressure, and a step (d) of continuing such a step of supplying, for at least 20 minutes, the carbon dioxide mist into the carbon dioxide gas mist-enclosing means, thereby to prevent, improve or curing the ischemic region of the living organism.

In place of the above step (d), it is also sufficient to measure concentration of the carbon dioxide gas mist in the carbon dioxide gas mist-enclosing means, and continue to supply carbon dioxide gas mist for at least 20 minutes in manner such that concentration of the carbon dioxide gas mist remains at or above prescribed value (as the description of the step (d′) shown in (B) part of FIG. 1).

By the way, the step (e) controls the supplying amount of the carbon dioxide gas mist and continues for 20 minutes or more, and preferably, continuation of 30 minutes or more is optimum for preventing, improving or curing ischemic region.

The carbon dioxide gas mist is characterized by containing a carbon dioxide gas mist of not more than 10 μm in diameter. Thereby, the carbon dioxide gas mist penetrates efficiently under the skin of the living organism through skin pores or the skin and mucous membrane of the living organism.

Air pressure in the carbon dioxide gas mist-enclosing means is characterized by being 1.01 to 2.5 air pressure. Since body-pressure of the living organism is almost equivalent to air pressure (1 air pressure), in this carbon dioxide gas mist pressure bath method, the carbon dioxide gas mist is controlled to contact the skin and mucous membrane of the living organism at pressure being higher than air pressure for more heightening permeability into a subcutaneous tissue.

In the carbon dioxide gas mist pressure bath method, the concentration of the carbon dioxide gas mist within the carbon dioxide gas mist-enclosing means is determined to be 60% or more.

A principle structure of a means generating the carbon dioxide gas mist is shown in FIG. 28. Water in a water tank T is injected from the inside of a carbon dioxide supply device G into a closed container C where carbon dioxide pressure is impressed to jet into an enclosed container C being under the carbon dioxide atmosphere, whereby carbon dioxide and water are pulverized and dissolved, so that the carbon dioxide gas mist is formed.

FIG. 2 is the typical view showing the outline of the first embodiment of the carbon dioxide gas mist pressure bath apparatus for preventing, improving or curing ischemic region of the present invention. The carbon dioxide gas mist pressure bath apparatus 10 has, as shown in FIG. 2, the carbon dioxide gas mist generating and supplying means 11, the pressure bath cover 12 (a carbon dioxide gas mist encircling means) for encircling the carbon dioxide gas mist together with the living organism under the sealing condition, a concentration meter 13 (concentration detecting means) for measuring concentration of the carbon dioxide gas mist within the pressure bath cover 12, and a control device 14 (control means) for controlling the supplying amount of the carbon dioxide gas mist from the carbon dioxide gas mist generating and supplying means 11 such that the concentration of the carbon dioxide gas mist becomes a predetermined value or more.

The carbon dioxide gas mist generating and supplying means 11 comprises a carbon dioxide supply means 111 for supplying carbon dioxide, a liquid supply means 112 for supplying a liquid, and a carbon dioxide gas mist generating means 113 for generating and supplying a gas mist (called as “carbon dioxide gas mist” hereafter) prepared by pulverizing and dissolving carbon dioxide from the carbon dioxide supply means 111 and the liquid from the liquid supply means 112.

The carbon dioxide supply means 111 is composed of, e.g., a gas bomb, and supplies carbon dioxide to the carbon dioxide gas mist generating means 113. This carbon dioxide supply means 111 is furnished, though omitting a drawing, with a regulator for adjusting gas pressure. There may be disposed a heater for heating gas and a thermometer for controlling temperature.

The liquid supply means 112 is composed of a pump or the like, and supplies the liquid to the carbon dioxide gas mist generating means 113. Otherwise, a supply means of gas mixing water such as, for example, an ozone water generating means is sufficient.

As the liquid to be supplied, it is preferable to employ water, ionic water, ozone water, physiological salt solution, purified water or sterilized and purified water. Further, these liquids are sufficient to contain medicines useful to users' diseases or symptom. As the medicines, for example, listed are anti-allergic agent, anti-inflammatory, anti-febrile agent, anti-fungus agent, anti-influenza virus agent, anti-influenza vaccine, steroid agent, anti-cancer agent, anti-hypertensive agent, cosmetic agent, or trichogen. Further, these liquids are further possible to generate synergistic effects by coupling with a gas physiological action with single or plurality of menthol having a cooling action; vitamin E accelerating circulation of the blood; vitamin C derivative easily to be absorbed to a skin tissue and having a skin beautifying effect; retinol normalizing a skin heratinizing action and protecting the mucous membrane; anesthetic moderating irritation to the mucous membrane; cyclodextrin removing odor; photocatalysis or a complex of photocatalysis and apatite having disinfection and anti-phlogistic; hyaluronic acid having excellent water holding capacity and a skin moisture retention effect; coenzyme Q10 activating cells and heightening immunization; a seed oil containing anti-oxidation and much nutrient; or propolith having anti-oxidation, anti-fungus, ant-inflummatory agent, pain-killing, anesthetic, and immunity. Otherwise the liquids may be added with ethanol, gluconic acid chlorohexizine, amphoteric surface active agent, benzalkonium chloride, alkyldiamino ether glycin acetate, sodium hypochlorite, acetyl hydroperoxide, sodium sesqui-carbonate, silica, povidone-iodine, sodium hydrogen carbonate. In addition, high density carbonate spring, bactericide or cleaning agent may be added (as examples organic components, sulfate, carbonate, sodium dichloroisocyanurate).

By the way, though not showing, preferably, there may be disposed a heater for heating liquid and a thermometer for controlling temperature in the liquid supply means 112.

The carbon dioxide gas mist generating means 113 is such a device for generating the carbon dioxide gas mist prepared by pulverizing and dissolving gas supplied from the carbon dioxide supply means 111 and liquid from the liquid supply means 112, and supplying it to a pressure bath cover 12. The diameter of the mist is optimum being not more than 10 μm. As the carbon dioxide gas mist generating means 113, for example, systems using a supersonic, an atomizing or fluid nozzles may be applied.

Next, the pressure bath cover 12 is composed of a cover main body 121 which covers the skin and mucous membrane of the living organism (herein, as the example, the human body) and forms a space of sealing inside the carbon dioxide gas mist. FIG. 3 shows the outline of the pressure bath cover, and FIG. 4 shows the condition of applying the pressure bath cover 12 to the human body. As shown in these Figures, the cover main body 121 is preferably composed of a bag shaped member of a pressure resistant, non-air permeable and non-moisture permeable materials. In this case, the cover main body 121 should be formed with soft materials such that it is folded or a user can move freely inside as seating on a seat while wearing (refer to FIG. 4). Concrete raw materials are desirable in regard to, for example, a natural rubber, silicone rubber, polyethylene, poly-propylene, polyvinylidene chloride, poly-stylene, polyvinylacetate, polyvinyl chloride, polyamide resin, or polytetrafluoroethylene.

The bag shaped cover body in FIG. 4 covers the whole body, and it is enough to surround only a part of the living body requiring improvement and promotion of blood circulation in the ischemic region by the carbon dioxide gas mist pressure bath. For example, for preventing, improving or curing ischemic heart disease, the bag shaped cover body is enough for surrounding only the upper half of the living body under an enclosed condition, and for preventing, improving or curing mainly arteriosclerosis obliterans choking a large artery of a lower extremity, the bag shaped cover body is enough for surrounding only the lower half of the living body.

The cover shaped main body 121 is illustrated here, and as later mentioning others, a box typed shape may be employed.

The cover main body 121 has an opening and closing part 122 for getting in and out the living body, and also has an open part 123 for exposing the head of the living body outside of the cover 12. Further, this cover main body 121 has an inlet port 124 for getting in the carbon dioxide gas mist inside and an outlet port 125 (exhaust means) for getting out the inside carbon dioxide gas mist. There may be provided a safety valve (by-pass valve) of automatically opening a valve when the inside of the pressure bath cover 12 goes above a predetermined pressure.

An opening and closing part 122 is preferably composed of a linear fastener (zipper) processed with a pressure resistant, non-air permeable and non-moisture permeable materials. Others as a face fastener is also sufficient.

An open part 123 is provided for exposing the head of the living body outside of the cover 12, and its periphery fits the open part 123 to the user around his neck for avoiding the carbon dioxide gas mist to leak from its clearance. The leakage avoiding means may use others such as a string, belt or face fastener.

An inlet port 124 communicates with the cover main body 121 for introducing the carbon dioxide gas mist into the pressure bath cover 12, and a carbon dioxide gas mist supply pipe 119 passes thereto for connecting the carbon dioxide gas mist generating means 113. The inlet port 124 has inside a check valve for avoiding back-flow of the carbon dioxide gas mist.

An outlet port 125 is an air hole for controlling internal pressure or concentration of the carbon dioxide gas mist by exhausting air within the pressure bath cover 12.

A concentration meter 13 is installed within the pressure bath cover 12, measures the concentration of the carbon dioxide gas mist, and outputs measuring values to a control device 14.

On the other hand, the control device 14 is composed of a computer having CPU, memory and display, keeps the concentration of the carbon dioxide gas mist within the pressure bath cover 12 to be a predetermined value or higher (preferably 60% or higher), and further for keeping, controls the carbon dioxide gas mist generating and supplying means 11 and the outlet port 125 of the pressure bath cover 12 on the basis of the measuring values of the concentration meter 13. As to others, the control device 14 may controls temperatures or pressure values in the pressure bath cover 12, and further, it has a timer function and enables the carbon dioxide gas mist pressure bath at a set time.

One example of the present carbon dioxide gas mist pressure bath apparatus will be concretely explained as follows. FIG. 5 is the typical view showing the carbon dioxide gas mist pressure bath apparatus 10A (First Embodiment) employing the carbon dioxide gas mist generating means of the atomizing system. Herein, a carbon dioxide gas mist generating means of the atomizing system 113′ is used as an example of the carbon dioxide gas mist generating means 113.

The carbon dioxide gas mist generating means 113′ is formed with a liquid storage 114 for storing a liquid from the liquid supply means 112, a nozzle 115A for discharging, from its front opening, carbon dioxide supplied from the carbon dioxide supply means 111, a liquid suction pipe 115B for sucking liquid stored in the liquid storage 114 up to its front end, and a baffle 116 positioned in opposition to the front end openings of the nozzle 115A and the liquid suction pipe 115B. Further, this apparatus 10A is furnished with a carbon dioxide supply part 117A, a carbon dioxide inlet part 117B, a carbon dioxide gas mist collection part 118A and a carbon dioxide gas mist outlet part 118B, these carbon dioxide supply part 117A and the carbon dioxide inlet part 1178 supplying carbon dioxide from the carbon dioxide supply means 111 into the carbon dioxide gas mist generating means 113′, the carbon dioxide supply part 117A and the carbon dioxide inlet part 117B introducing carbon dioxide around the nozzle 115A and making air flow for exhausting the carbon dioxide gas mist, and the carbon dioxide gas mist collection part 118A and the carbon dioxide gas mist outlet part 118B collecting the carbon dioxide gas mist and exhausting the carbon dioxide gas mist. The carbon dioxide gas mist discharged from the carbon dioxide gas mist outlet part 118B is supplied into the pressure bath cover 12 through a carbon dioxide gas mist supply pipe 119.

By the way, this carbon dioxide gas mist pressure bath apparatus 10A is also installed with a manometer 151 other than a concentration meter 13 within the pressure bath cover 12. The control device 14 performs controls based on their measuring values. For example, air pressure within the pressure bath cover 12 is controlled to be not lower than 1 (more preferably, 1.2 to 2.5 air pressure). Further, in case air pressure within the pressure bath cover 12 exceeds a predetermined value, it is sufficient to stop the carbon dioxide gas mist generating and supplying means 11 and to control to discharge from an outlet.

Further, in this carbon dioxide gas mist pressure bath apparatus 10A, between the carbon dioxide supply means 111 and the carbon dioxide supply part 117A of the carbon dioxide gas mist generating means 113′, a flow valve 141 is provided to enable adjustment of the gas flowing amount to the carbon dioxide gas mist generating means 113′ and at the same time, a switch valve 142 is provided in the carbon dioxide gas mist supply pipe 119 for switching the carbon dioxide gas mist from the carbon dioxide gas mist outlet part 118B of the carbon dioxide gas mist generating means 113′ with carbon dioxide from the carbon dioxide supply means 111, so that the carbon dioxide gas mist concentration within the pressure bath cover 12 can be adjusted.

Next explanation will be made to a sequence of performing the carbon dioxide gas mist pressure bath using the present carbon dioxide gas mist pressure bath apparatus 10A. The user opens at first an opening and closing part 122, gets himself into the cover main body 121, suitably meets an open part 123 to his neck, closes the opening and closing part 122, and makes a sealed condition.

Then, the liquid is poured from a liquid supply means 112 into the liquid storage 114 of the carbon dioxide gas mist generating means 113′, and subsequently carbon dioxide is supplied from the carbon dioxide supply means 111 into the carbon dioxide gas mist generating means 113′.

When carbon dioxide is supplied to the nozzle 115A, since the nozzle 115A is reduced in diameter toward the front end as seeing in FIG. 5, carbon dioxide heightens flowing rate and gets out. Liquid is sucked up within a liquid suction pipe 115B owing to negative pressure generated by air flow at this time, blown up by carbon dioxide at the front end (nozzle front end), collided with the baffle 116, and turns out a mist. Carbon dioxide is also further supplied from the carbon dioxide supply part 117A and the carbon dioxide inlet part 117B into the carbon dioxide gas mist generating means 113′, and heightens exhausting pressure of the carbon dioxide gas mist. The generated carbon dioxide gas mist passes through the carbon dioxide gas mist collecting part 118A and the carbon dioxide gas mist outlet part 118B, and comes to the pressure bath cover 12 from the carbon dioxide gas mist supply pipe 119. The control device 14 is based on the values of the concentration meter 13 and the manometer 151, and controls the carbon dioxide gas mist generating and supplying means 11 and the outlet port 125 of the pressure bath cover 12, and carries out the carbon dioxide gas mist pressure bath until a predetermined time of a timer passes.

Preferably, the carbon dioxide gas mist supply pipe 119 is composed wholly or partially with a soft and cornice shaped pipe of large diameter. Since the cornice shaped pipe is freely bent or expanded, the user's action is not limited. Further, if the cornice shaped pipe is formed inside with a groove in an axial direction and in case the gas mist flows in the gas mist is liquidized, liquid drops can be gathered for easily recovered.

The above mentioned has shown an example of supplying the carbon dioxide gas mist into the pressure bath cover 12 through one inlet port 124 from one carbon dioxide gas mist generating and supplying means 11, and instead of this example, it is sufficient to supply the carbon dioxide gas mist via a plurality of inlet ports from a plurality of carbon dioxide gas mist generating and supplying means. In addition, the above example has explained as to the human body as a living body to be applied with the present carbon dioxide gas mist pressure bath device 10, but not limiting to the human body, other animals (for example, racing horses, pets and others) may be applied with.

FIG. 6 is the typical view showing the condition that the carbon dioxide gas mist pressure bath apparatus employing a plurality of the carbon dioxide gas mist generating and supplying means is applied, for example, to a horse. As to the same parts of FIG. 2, the same numerals and signs will be given to omit detailed explanations.

As shown in FIG. 6, the carbon dioxide gas mist pressure bath 20 has the plurality (herein, two, as an example) of carbon dioxide gas mist generating and supplying means 21A, 21B. A horse pressure bath cover 22 is formed in that a cover main body 221 has a size covering almost all of the whole body of the horse, having an opening and closing part 222 and an opening part 223 with the plurality (herein, two, as an example) of inlet ports 224A, 224B and an outlet port 225.

The inlet ports 224A, 224B are connected to the carbon dioxide gas mist generating and supplying means 21A, 21B, respectively. Herein, it is allowed that each of carbon dioxide gas mist generating and supplying means 21A, 21B generates the carbon dioxide gas mist from different liquids for giving actions of the respective liquids to the living body.

The above mentioned has explained the pressure bath cover 12 composed of the bag shaped cover main body 121, and the pressure bath cover 12 is not limited thereto but applicable to various shapes. FIG. 7 is the typical view showing the outline of the carbon dioxide gas mist pressure bath apparatus (the second embodiment) having the pressure bath cover of a box type enabling to be stationary. As to the same parts of FIG. 2, the same numerals and signs will be given to omit detailed explanations. FIG. 8 shows the outline of the pressure bath cover of the carbon dioxide gas mist pressure bath device depending on the present embodiment. FIG. 9 shows the condition of applying the box type pressure bath cover of to the human body.

As shown in FIG. 7, the carbon dioxide gas mist pressure bath apparatus 30 has the carbon dioxide gas mist generating and supplying means 11 of generating and supplying the carbon dioxide gas mist, the pressure bath cover 32 for enclosing the carbon dioxide gas mist gas mist together with the living body under an air tight condition (the carbon dioxide gas mist enclosing means), the concentration meter 13 (the concentration detecting means) of measuring the concentration of the carbon dioxide gas mist within the pressure bath cover 32, and the control device 14 (the control means) of controlling the supplying amount of the carbon dioxide gas mist from the carbon dioxide gas mist generating and supplying means 11. Further, the manometer 151 is provided, and when air pressure within the pressure bath cover 32 becomes higher than the predetermined value, the manometer 151 stops the carbon dioxide gas mist generating and supplying means 11, and also controls exhausting of the carbon dioxide gas mist within the pressure bath cover 32 from the outlet port. There may be provided a safety valve (by-pass valve) of automatically opening a valve when the inside of the pressure bath cover 32 goes above a predetermined pressure.

The pressure bath cover 32 is composed of a box typed cover main body 321 being sized to enable to cover almost the whole of the living body. That is, it is formed with an upper part 322, bottom part 323, plural (herein, four) side parts 324 (324A, 324B, 324C and 324D). Among of them, one side (herein, as an example, 324A) is an openable and closable gate 325 as seeing in FIG. 8(b) as the user goes into and out from the pressure bath cover 32. This gate 325 has a handle 325A. Omitting illustration, the handle is desirably furnished inside so that the gate 325 can be opened and closed at the inside.

At the upper part 322 of the cover main body 321, an opening 326 is formed for exposing the user's head outside of the cover 32. Further, around a periphery of the opening 326, a leakage prevention means 327 is provided for avoiding leakage of the carbon dioxide gas mist from a clearance. Herein, inside of the opening 326, a non-air permeable material (for example, polyethylene seat) having an opening 327A is furnished, and the edge of this opening 327A is attached with a member such as a rubber having an expansion, and the user is fitted at his neck. Instead of the rubber, a string, belt or face fastener are sufficient.

A pressure bath cover 32 is connected to the carbon dioxide gas mist supply pipe 119 and has an inlet port 328 for introducing the carbon dioxide gas mist into the inside. This inlet port 328 is equipped inside with a check valve for avoiding back-flow of the carbon dioxide gas mist. Further, the pressure bath cover 32 has an outlet port 329 for adjusting inside pressure or concentration of the carbon dioxide gas mist by issuing gas in the pressure bath cover 12. The outlet port 329 opens and closes based on an order of the control device 14.

Incidentally herein, a chair 330 is placed within the pressure bath cover 32 for the user to carry out the carbon dioxide gas mist pressure bath as seating on it. For this chair 330, preferably it may change a seating height meeting the user's sitting height.

For taking the carbon dioxide gas mist pressure bath, using the pressure bath cover 32 of the present embodiment, the user at first opens the gate 325 of the cover 32, enters into the cover main body 321, and adjusts the height of the chair 330 so that the head is into position as to the opening 326. Next, he seats on the chair 330 and passes the head through an opening 326, sets a leakage prevention means 327 around the neck to prevent leakage of the carbon dioxide gas mist. Then, the gate 325 is closed to make the inside of the cover 32 almost sealing. Under this condition, the carbon dioxide gas mist is supplied from the carbon dioxide gas mist generating and supplying means 11 to carry out the carbon dioxide gas mist pressure bath.

Up to here, the example has been shown that the chair 330 is prepared in the pressure bath cover 32 and the user takes the carbon dioxide gas mist pressure bath as seating, and the pressure bath cover 32 may be changed into such a shape for other postures. FIG. 10 shows the pressure bath covers 32 for taking the carbon dioxide gas mist pressure baths by other postures.

FIG. 10(
a) shows a pressure bath cover 32a for a standing posture. As is seen, the pressure bath cover 32a for the standing posture is formed as vertically formed shape. The cover main body 321a is provided with an opening 326a and a leakage prevention means 327a. Further, there are provided an inlet port 328a of the carbon dioxide gas mist, an outlet port 329a and a gate 325a for going and out.

FIG. 10(
b) shows a pressure bath cover 32b for a lying posture. As is seen, the pressure bath cover 32b for the lying posture is formed as horizontally formed shape. The cover main body 321b is provided with an opening 326b and a leakage prevention means 327b. Further, there are provided an inlet port 328b of the carbon dioxide gas mist, an outlet port 329b and a gate 325b for going and out.

By the way, similarly to the above mentioned first embodiment, the living body to be applied with the pressure bath cover 32 is not limited to the human body, but other animals (for example, racing horses, pets and others) may be applied with.

FIG. 5 has shown the carbon dioxide generating and supplying means 113′ as the concretely structured example, and further, while referring to FIG. 53, explanation will be made to a carbon dioxide generating and supplying means 130 of another structured example. FIG. 53 is the cross sectional and typical view showing the structure of the carbon dioxide generating and supplying means 130, and this carbon dioxide generating and supplying means 130 previously stores liquid inside, generates the gas mist prepared by pulverizing and dissolving liquid and gas by high speed flowing of gas supplied from the carbon dioxide supply means 111, further mixes gas, and supplies it to the pressure bath cover 12 shown in FIG. 2.

As shown in FIG. 53, the carbon dioxide gas mist generating means 130 is furnished with a connection part 131 connected with the gas supply means 111, a branch 132 of diverging gas flow from the connection part 131, a liquid storage 133 of storing liquid, a nozzle 134 of discharging one side gas flow diverged at the branch 132, a liquid sending pipe 135A of sending liquid to the front end of the nozzle 134, a baffle 136 (a collision member) of colliding liquid blown up by gas flow jetted by the nozzle 134 and generating the gas mist, a confluent part 137 of making gas from upward confluent with the gas mist, a gas introduction part 138 of guiding the other side gas flow diverged at the branch until the confluent part 137, and a gas mist discharging part 139 of collecting the gas mist to discharging, and these members are integrally formed as one body.

The connection part 131 is connected with the gas supply means 111 directly or via a gas code. The structure of the connection part 131 is enables to connect a gas code communicating with the gas supply means 111, or directly connect the gas supply means 111, and depending on the gas supply means 111 to be connected, various forms may be applied.

The gas supplied from the gas 111 via the connection part 131 is branched into two at a branch. One of them directs to the nozzle 134 while the other goes to the gas introduction part 138. The gas directing to the nozzle 134 is exhausted from the nozzle front end 134A while the going to the gas introduction part 138 is guided until the confluent part 137.

The liquid storage 114 of the carbon dioxide gas mist generating means 113′ shown in FIG. 5 has a structure of directly receiving the liquid from the liquid supply means 112, but in the carbon dioxide gas mist generating means 130 of FIG. 53, a predetermined liquid is previously stored at a manufacturing step and sealed. When using, it is opened to take the gas mist pressure bath. But the stored liquid is the same as that of the liquid storage 114 of the carbon dioxide gas mist generating means 113′, and as above stated, water, ionic water, ozone water, physiological salt solution, purified water or sterilized and purified water are employed, and further it is also sufficient to contain medicines useful to users' diseases or symptom into these liquids.

At the central part of the liquid storage 133, a nozzle 134 is positioned. This nozzle 134 rises from the bottom of the liquid storage 133 and is formed almost conically toward the baffle 136. The nozzle 134 connects at its basic end to one of diverges 132 so that the gas can be exhausted from the nozzle front end 134A.

The liquid suction pipe 135A is formed between the outer circumference of the nozzle 134 and the inner circumference of the liquid suction pipe forming member 135 of the almost circular cone being larger by one turn than the nozzle 134. That is, as shown in FIG. 53, by positioning as covering the liquid suction pipe forming member 135 over the nozzle 134, the liquid suction pipe 135A is defined between the outer circumference of the nozzle 134 and the inner circumference of the liquid suction pipe forming member 135. Since a nail shaped projection (not showing) is provided at a base end (the lower portion of the almost circular cone) of the liquid suction pipe forming member 135, a space is formed at a base of the liquid suction pipe forming member 135 and the bottom of the liquid storage 133, so that the liquid stored in the liquid storage 133 is sucked up from this space by the liquid suction pipe 135A. In addition, the front end 135A of the liquid suction pipe forming member 135 opens nearly the front end open 135B of the nozzle 134, and the liquid sucked up by the liquid suction pipe 135A collides against the gas flow discharged from the nozzle 134.

The liquid sucked up by the liquid suction pipe 135A collides against the gas flow discharged from the nozzle 134 and is blown up, and collides against the baffle 136 disposed in opposition to the front end open 134A of the nozzle 134 and is pulverized so that the gas mist is generated. Herein, the baffle 136 is secured to the inside wall of the confluent part 137, but may be secured to the liquid suction pipe forming member 135.

On the other hand, the gas which is branched at the diverge 132 into a gas introducing part 138 goes along the gas introducing part 138 and reaches the confluent part 137. The gas introducing part 138 is a guide passage of the gas which directs upward the upper part passing through the side inside of the carbon dioxide gas mist generating means 130 from the diverge 132 provided at the lower part of the carbon dioxide gas mist generating means 130, and the gas introducing part 138 is formed integrally with the carbon dioxide gas mist generating means 130. Further, the confluent part 137 is composed of a cylindrical member disposed as encircling the baffle 136 above the front end open 134A of the nozzle 134, and communicates with the gas introducing part 138. Accordingly, the gas branched at the diverge 132 and guided into the gas introducing part 138 merges upward with the gas mist generated in the confluent part 137, and extrudes the gas mist toward a gas mist exhaust part 139.

The gas supplied from the gas introducing part 138 to the confluent part 137 can adjust supply pressure by sizes of diameters of a gas introducing part 138. By adjusting gas supply pressure, it is also possible to adjust the gas mist supply amount of the carbon dioxide gas mist generating means 130. In addition, it is possible to adjust the gas mist concentration (the mist concentration in the gas) and sizes of the mist by the gas introducing part 138.

The gas mist exhaust part 139 is a space defined in a periphery of the cylindrically shaped confluent part 137, collects the gas mist driven from the confluent part 137 by the gas from the gas introducing part 138, and exhausts it together with the gas. The gas mist driven by the gas mist exhaust part 139 is exhausted into the pressure bath cover 12 from a gas mist exhaust part 139A which is an exit positioned at the upper part of the carbon dioxide gas mist generating means 130. Between the gas mist exhaust part 139A and the pressure bath cover 12, the carbon dioxide gas mist supply pipe 119 connects.

The carbon dioxide gas mist generating means 130 may have such a structure where a part including the liquid storage 133 is made removable and replaceable with another new liquid storage 133. That is, the carbon dioxide gas mist generating means 130 is made fabricated, and by fabricating a replacing part including the liquid storage 133 with another part, the carbon dioxide gas mist generating means 130 made one body of the gas introducing part 138 is accomplished. Thus, by making the liquid storage 133 replaceable, the liquid storage 133 is made disposable, keeping hygienic. Further, by making the liquid storage 133 replaceable, the structure of supplying the liquid into the liquid suction pipe 135A is omitted. Preferably, the carbon dioxide gas mist generating means 130 has been sterilized in the producing stage.

In the above mentioned carbon dioxide gas mist generating means 130, the gas mist is generated as under. When the gas is supplied from the gas supply means 111 and since the nozzle 134 is reduced in diameter toward the front end, gas increases the flowing speed and is exhausted. The liquid in the liquid storage 133 is sucked up within the liquid suction pipe 135A owing to negative pressure caused by air flow at this time, is blown up by gas at the front end portion 135B of the liquid suction pump 135A, and collides against the baffle 136, so that the mist is generated. Desirably, the diameter of the mist generated by this collision is fine, and concretely, best is not larger than 10 μm. The thus finely pulverized mist can display effects of minus ion.

The gas passes through the branch 132, is guided into the confluent part 137 from the gas introducing part 138 and heightens exhausting pressure of the generated gas mist. The generated mist is mixed with gas from the branch 132 and discharged from the gas mist exhaust part 139. That is, explaining with FIG. 5, the gas mist is supplied into the pressure bath cover 12 via the carbon dioxide gas mist supply pipe 119.

The pressure bath covers 12, 22, 32, 32a and 32b having been explained receive all of the living body excepting a head part, and those covering the skin and mucous membrane of local body parts are sufficient. FIG. 54 is the typical view showing the outline of the third embodiment of the carbon dioxide gas mist pressure bath apparatus according to the present invention. The pressure bath cover 150 herein covers a local part of the living body (in the present FIG., as an example, a forearm of the human body), and forms the space for sealing the gas mist and gas inside. The pressure bath cover 150 is composed of a first cover 161 (an inner cover) positioned inside and a second cover 155 (an outer cover) positioned outside and covering the whole of the first cover 161. The pressure bath cover 150 is suitably composed of a pressure resistant, non-air permeable and non-moisture permeable materials, and for example, a natural rubber, silicone rubber, polyethylene, poly-propylene, polyvinylidene, polystylene, polyvinyl acetate, polyvinyl chloride, polyamide resin, polytetrafluoroethylene.

The inner cover 161 is an almost bag shaped cover for partially covering parts of high absorption rate of the gas mist, and concurrently serves as a cover of heat insulation. That is, temperature increases in the living body covering member 150 as time passes, and then the gas mist of comparatively cool temperature generated at room temperature is supplied, but the inner cover 161 is preferably composed of a heat insulating material. By attaching the inner cover 161, the gas mist supplied during taking the gas mist pressure bath can be avoided from gasification. The inner cover 161 is higher in effects by attaching to parts wanting in particular the gas mist to be absorbed, or palms, planters, or easily sweating in parts of many sweat glands.

The inner cover 161 has an inlet port 152 connected to the gas mist supply pipe 119 for introducing inside the gas mist and gas. The inlet port 152 is, though not shown, provided inside with a check valve for avoiding back flow of the gas mist and gas. The inner cover 161 is an open 154 in this embodiment. Accordingly, the gas mist and gas supplied in the inner cover 161 are also concurrently supplied to an outer cover 155 through the open 154.

The outer cover 155 is larger than the inner cover 161, enables to cover the skin and mucous membrane of the living organism and the whole of the inner cover 161, and formed as an almost bag shaped cover. The outer cover 155 is provided at its opening part with a stopper 157 which enables to attach to and detach from the living organism and prevents leakage of the gas mist and gas. The stopper 157 is preferably composed of a face fastener having, e.g., stretchability. Otherwise, a string or rubber or the like may be used solely or in combination. Since the outer cover 155 necessitates sealing property, the stopper 157 may have inside such a material adhering to the skin of the living organism. This adhesive material is desirably a visco-elastic gel made of polyurethane or silicone rubber. In addition, this visco-elastic material is detachably furnished, and can be desirably exchanged if viscosity becomes lower.

Further, the outer cover 155 has a connecting part 158 which is connected to the inlet port 152 of the inner cover 161 and connects the inner cover 161 and the carbon dioxide gas mist supply pipe 119 while sealing the outer cover 155. Desirably, the outer cover 155 is, though not shown, provided with a gas mist exhaust port for getting out the gas mist and gas from the inside of the cover, and with a valve for adjusting pressure of the inside of the cover. The adjustment of pressure within the cover may depend on manual operation, but desirably it depends on automatic operation by a control device 160 together with supply control of the gas mist. Further, there is desirably provided a safety valve (dischargeable valve) which opens automatically when the inside of the outer cover 155 exceeds a predetermined pressure value.

The example herein is that the connecting part 158 is connected to the inlet port 152, and any embodiments are applicable, as far as being such a structure enabling to supply the gas mist into the inner cover 161 while closing the inside of the outer cover 155.

Inside of the outer cover 155, a manometer 171 is placed for measuring its inside pressure. The control device 160 controls generation and supply of the gas mist based on the measuring values of the manometer 171 for keeping the pressure value inside the outer cover 155 to be 1 air pressure or higher (to be more preferably, 1.01 to 2.5 air pressure). For example, the supply of the gas from a gas supply means 110 is controlled or stopped, and the gas mist and gas are discharged from the inner cover 161 or the outer cover 155. By the way, since this embodiment uses the pressure bath cover 150 of the inner cover 161 opening by an open 154, the manometer 171 is enough with one provided in the outer cover 155. Within the inner cover 161 or within the outer cover 155 (herein, within he inner cover 161), a thermometer 172 may be installed for measuring temperature. The control device 160 performs “ON-OFF” of supplying the gas mist.

As to others, within the pressure bath cover 150, there may be installed sensors for measuring the concentrations of oxygen, carbon dioxide or moisture in order to control the circumstances in the covers to be within predetermined ranges of respective values by a control device 160.

The control device 160 is composed of a computer having CPU, memory and display, and performs each of controls such as gas pressure control or ON-OFF switch, or ON-OFF switch of the gas mist supply for taking the gas mist pressure bath under optimum conditions. In particular, the control device 160 adjusts each of several means from measuring values of the manometer 171 or thermometer 172 installed in the pressure bath cover 150 in order to maintain optimum conditions for taking the gas mist pressure bath. It is suitable to make a structure, such that, in case the pressure value in the pressure bath cover 150 becomes higher than the predetermined value, the gas supply of the gas supply means 110 is stopped by the control device 160. Incidentally, the above adjustment may be manual not using the control device 160.

Next, as to the tested results of many animal tests showing improvements or acceleration of blood circulation in the ischemic regions by the carbon dioxide gas mist pressure bath treatment depending on this invention, explanations will be made in detail, referring to Tables and graphs.

The individuals used to experiments were wild type male mice aged of 8 to 10 weeks. Those mice were put under anesthesia with pentobarbital, and incised at left femoral regions under a micro-scope. Femoral nerves were preserved, and femoral arterio veins were exfoliated from the neighboring tissues and surgically extracted. By the way, the artery extracted parts extended from center sides of branching parts of superficial epigastric veins of the arteria femoralis to arteria poplitea, and arteria profunda femores existing between those parts were ligated (two parts), and ischemic models of the lower extremity were made.

These individuals were classified into [1] Individual group of non-treated (NM), [2] Individual group where synthetic air (containing 80% nitrogen/20% oxygen) was sealed under pressure in the gas mist pressure bath means to perform a mist treatment (AIRM), [3] Individual group where 100% oxygen gas mist was sealed under pressure in the gas mist pressure bath means to perform the mist treatment (OM), [4] Individual group where 100% carbon dioxide gas mist was sealed under pressure in the gas mist pressure bath means to perform the mist treatment (CM), and [5] Individual group where nitrogen monoxide enzymes for synthesis (NOS) and inhibitor (L-NAME) were dosed (CM+L) in addition to 100% carbon dioxide gas mist treatment.

The carbon dioxide gas mist treatment is performed every day under anesthesia for 10 minutes in that the mice are covered at the lower extremities with polyethylene bags and the inlet opens of the bags are tightened with ring-rubbers, and then the gas mist is filled into them.

For measuring blood flow of the individuals, a laser Doppler meter was employed, and the LDBF measurements were carried out time-sequentially after 28 days from the pre model-making of the ischemic models of the lower extremities, and the blood flowing images obtained by the LDBF measurement were taken in the computer for performing the quantitative analyses, and the blood flow ratios (I/N ratio) of the patient-sides to the healthy-sides were calculated. Further, the blood capillary density in the femur adductor being the ischemic range was performed with the immune tissue staining, using the anti-CD31 antibody, and then quantified.

FIG. 11 shows the blood flows measured by the laser Doppler blood flow meter immediately after the surgeries (ischemia-making) of the respective groups and on 28th day. FIG. 12 shows, in I/N ratios, the changes of the blood flows immediately after making-ischemia of the respective groups and after passing of 4, 7, 14, 21 and 28 days. Immediately after ischemia, I/N ratios of the respective groups were lower than 0.1, and the blood flow was hardly recognized. As to the numbers then of the individuals, (NM) group was the 14, (AIRM) group was the 15, (CM) group was the 18 and (CM+L) was the 8 individuals. This data added also the 9 individual groups where 100% oxygen mist was sealed under pressure into the gas mist pressure bath means.

Immediately after making the ischemia, in all the groups, I/N ratio went down below 0.05. I/N ratio of (NM) group improved till about 0.35 after 7 days from making the ischemia, till about 0.52 after 14 days, till about 0.52 after 21 days and till about 0.6 after 28 days.

I/N ratio of (AIRM) group recovered till about 0.5 after 7 days from making the ischemia, but recognized no difference from the NM group after 14 days from making the ischemia. The individual groups of 100% oxygen mist also showed the similar tendencies as (AIRM) group.

I/N ratio of (CM) group improved till about 0.55 after 7 days from making the ischemia, till about 0.7 after 14 days and till 0.78 after 28 days, and recognized significant improvement after 7 and following days in comparison the NM group. Although (CM+L) group was treated with the carbon dioxide gas mist, it showed that I/N ratio was restrained by dosage of L-NAME.

No difference was recognized between the 100% oxygen mist treated group and the AIR group, and therefore, the data concerning 100% oxygen mist treatment in other results are omitted.

FIG. 13 shows the results of having taken out the ischemic part tissues (femur adductor) of (NM) group, (AIRM) group, (CM) group and (CM+L) group after 28 days from making the ischemia, and having performed the immune tissue staining with anti-CD31 antibody. FIG. 14 shows the results of having performed, based on FIG. 13, the quantitative analyses of the blood capillary density per 1 mm²of (NM) group, (AIRM) group, (CM) group and (CM+L) group, and (CM) group shows the highest value. The increase of the blood capillary density observed in the CM group was not observed in the CM+L group.

FIGS. 15 to 20 are concerned with (NM) group, (AIRM) group, (CM) group and (CM+L) group, and show relatively increase and decrease of mRNA expression in the cells. The cell synthesizes various proteins based on mRNA (transfer ribonucleic acid), and FIGS. 15, 16 and 17 show respectively the ratios of VEGF (vascular endothelial cell growth factor) to GAPDH (glyceraldehydes 3-phosphate dehydrase), FGF (fibroblast growth factor) to GAPDH, and eNOS (endodermis-typed NO synthetic enzyme) to GAPDH, which are synthesized after 4 days from ischemia-making. FIGS. 18, 19 and 20 show respectively the ratios of VEGF to GAPDH, FGF to GAPDH, and eNOS to GAPDH, which are synthesized after 7 days from ischemia-making.

GAPDH is regarded as protein less varied by such as cell irritation, and by demanding a ratio with simultaneously measuring GAPDH, the relative quantities of VEGF•FGF•eNOS are shown. FIGS. 15 to 20 show that VEGF and FGF playing important plays for regenerating blood vessels more increase in comparison with other groups by carrying out the carbon dioxide gas mist treatment.

FIG. 21 shows the amounts of nitric acid contained in plasma after 4 days from ischemia per (NM) group, (AIRM) group and (CM+L) group. The content of nitric acid effective to expansion of blood vessel is highest in (CM) group.

FIG. 22 measures, based on the measurement of light absorption, the oxygen amounts of the tissues at making the ischemic models of rat-lower extremities, and shows the degrees of saturated oxygen (StO2) in the tissue, which are the ratios of oxyhemoglobin (oxyHb) to total hemoglobin, deoxyhemoglobin (deoxyHb) to total hemoglobin, and oxyhemoglobin to total hemoglobin. At about 4 minutes after starting the measurement, arteria femoralis was ligated, and about at 11 minutes, main tubes were ligated, and since oxyHb largely decreased after ligating the main tubes, the degree of saturated oxygen (StO2=oxyHb/total Hb) in the tissue remarkably also went down.

FIGS. 23 and 24 measure, under light absorption, the oxygen amount in the tissue after 6 days from ischemia during the carbon dioxide gas mist treatment and during the synthetic air treatment, and show the degree of saturated oxygen (StO2) in the tissue, which are the ratios of oxyhemoglobin (oxyHb) to total hemoglobin, deoxyhemoglobin (deoxyHb) to total hemoglobin (total Hb), and oxyhemoglobin to total hemoglobin.

FIGS. 25 and 26 measure the oxygen content of the tissues after 6 days from ischemia during treating synthetic air and during treating the carbon dioxide gas mist, showing with the ratios of oxyhemoglobin (oxyHb) to total hemoglobin (total Hb), deoxyhemoglobin (deoxyHb) to total hemoglobin, and oxyhemo globin to total hemoglobin. FIGS. 25 and 26 show that the carbon dioxide gas mist treatment increases oxyhemoglobin in comparison with the synthetic air treatment.

FIG. 27 shows “number of identification protein by iTRAQ and LC/MS/MS” and influences to protein by the carbon dioxide gas mist treatment after ischemia of lower extremity. For analyzing mass and identification of proteins, the respective protein specimens (samples) are modified with four kinds of reagents (114, 115, 116, 117) of iTRAQ (isobaric tags for relative and absolute quantitation), and the modified samples are mixed to make samples for mass analyses. In MS/MS spectral of the individual peptides, signals reflecting amino acid sequence as well as reporter ions reflecting protein mass contained in the respective samples are observed. To compare and investigate signal strength identified in MS/MS analysis is, that is, to compare and determine by utilizing indication of ratio of the respective peptide contents. By this procedure, it is possible to clarify availability of the carbon dioxide gas mist to occurrence level of protein within the cell (in particular, skeletal muscle).

The high absorption effect of carbon dioxide by the carbon dioxide gas mist pressure bath treatment in accordance with the present invention is proved by the various test results by the animal experiments. In the following, explanation will be made referring to Tables and Graphs.

At the outset, almost all (abundance ratio 98.93%) of carbon existing on the earth is 12(¹²C) in the atomic weight, but carbon (¹³C) of the atomic weight 13 as the stable isotope exists 1.07%. The stable isotope ¹³C has no radioactivity and is a half-permanently stable isotope. CO₂existing in the living body is also almost ¹²CO₂similarly in atmospheric air.

Then, artificially produced ¹³CO₂of high concentration (99%) was caused to carry out dermal desperation in rats with the carbon dioxide gas mist pressure bath apparatus of this invention, and quantitative analyses were performed on ¹²CO₂derived from respiration of an isotope of two kinds of carbon dioxide CO₂as well as on ¹³CO₂derived from dermal respiration, so that it could be proved whether or not dermal respiration was made effectively. In this way, the experiments were divided into the group treated with the ¹³CO₂mist depending on the carbon dioxide gas mist pressure bath apparatus of this invention and the non-treated group, and the experiments analyzed a distribution of ¹³CO₂absorbed from the skin into an internal organ.

The analyses used the specimens of 16 pieces in total of the frozen tissues of plasmas, hearts, livers and muscles of the two kinds of rats No. 1 and No. 2 which had not been subjected to the carbon dioxide gas mist pressure bath treatment by ¹³CO₂(called as “non-treated No. 1” and “non-treated No. 2” hereafter) as well as the specimens of plasmas, hearts, livers and muscles of the two kinds of rats No. 1 and No. 2 which had been subjected to the carbon dioxide gas mist pressure bath treatment by ¹³CO₂(called as “¹³CO₂mist treated No. 1” and “¹³CO₂mist treated No. 2” hereafter), and the analyses detected carbonic acids (¹²CO₂and ¹³CO₂) from the 16 specimens. In the following, explanation will be made to the procedures and results of the analyses and tests in order.

(1) Analyzing and Testing Manners

(1.1) Setting of Measuring Conditions

(1.1.1) Preparation of Standard Solution

Sodium carbonate was dissolved in water to prepare the solution of an arbitrary concentration, and a fixed amount was collected in a measuring vial, added with sulfuric acid and sealed. Amount of carbonic acid in the measuring vial was 5 levels of 10, 50, 100, 250 and 500 μg, and their controls were performed in the glove box of in a nitrogen gas atmosphere.

(1.1.2) Measure

The gas phase of the measuring vial was measured by a gas chromatogram mass analysis under the under conditions.

Column: Pora BOND Q length 25 m • inner diameter 25 mm • film thickness 3 μmm

Column temperature: 40° C. (8 minutes)

Carrier gas: He

Sample injection: Head space (60° C., 1 minute heating)

Ionization: Electron ionization (EI method: 70 eV)

Measuring mode: Selection ion monitoring (SIM)

Monitor ion: Quantitative ion m/z44 (¹²CO₂), m/z45 ¹³CO₂

(1.1.3) Preparation of Analytical Curve

The standard solution was measured, the concentration (μg/vial) was plotted on the vertical axis, and the peak area of CO₂detected from the chromatograph of the extracted ion current (EIC) of m/z44 was plotted on the lateral axis, and the analytical curve was prepared.

(1.2) Analysis of Rat Tissue

(1.2.1) Pre-Treatment

The aqueous sodium hydroxide solution was added to the sample, defrosted and uniformed in a mortar, and its determined amount was collected in the measuring vial into which sulfuric acid was added and sealed. These operations were performed in a glove box under nitrogen gas atmosphere. The operation after making uniform in the mortar was repeated one to three times per one sample.

(1.2.2) Calculation of Analyzed Values

After measuring the samples in the measuring vial after the pre-treatment, CO₂of measured m/z44 and m/z45 was determined. The detected amount of CO₂was divided by the sample amount, and the amounts of ¹²CO₂and ¹³CO₂per sample mass were found.

Further, for correcting effects of the natural isotope (m/z45) existing in CO₂derived from respiration, the amount of ¹³CO₂found from the amount of ¹²CO₂was deducted from the detected amount of ¹³CO₂and the amount of ¹³CO₂derived from the dermal respiration, that is, absorbed by the gas mist treatment was calculated.

(2) Analyses and Test Result

(2.1) Validity of Measuring Condition

(2.1.1) Linearity of Analytical Curve

FIG. 29 is the measured EIC chromatogram where the upper is the volume of ¹²CO₂and the lower is the volume of ¹³CO₂. The chromatogram shows the holding time on the lateral axis and the concentration on the vertical axis, and the area (peak area) of a triangular part of a normal distribution is the measured volume of ¹²CO₂. FIG. 30 shows the analytical curve of a prepared ¹²CO₂, where the coefficient (R) of correlation is a quadratic curve being a straight line approximate as 0.9987.

(2.1.2) Reproducibility of Repeated Measures

As a result of repeating measurements of standard solution of carbonic acid being 500 μg, duplicability within day was 3 to 5% of the relative standard deviation (RSD), and duplicability within a period (10 days) of measuring the specimens was 11% of RSD.

As a result of repeating the specimens uniformed in the mortar from the pre-treatment of sampling into the measuring vial to measuring, RSD showed the high reproducibility of less than 20% in all the specimens. By the way, while RSD of the standard solution was 3 to 5%, RSD of the specimens was less than 20%, and the causes therefor may be considered as shortage of uniforming the specimens or time lag per adding or sealing reagents, but such causes are considered no problem as a reproducibility level.

(2.2) Result of Analyzing Issues of Rats

FIGS. 31 to 46 show the measured results by the EIC chromatograph in each of 16 samples. In each of them, the upper is the volume of ¹²CO₂and the lower is the volume of ¹³CO₂.

The volumes of CO₂were measured in the peak area of each chromatographs, showing the lateral axis is the holding time and the vertical axis is the concentration, and the values of CO₂of the measured m/z44 (the upper) and m/z45 (the lower) were determined by the analytical curves.

Table 1 shows the determined results of ¹²CO₂and ¹³CO₂of each of the samples.

For example, the chromatograph of FIG. 31 shows the volume of ¹²CO₂in the plasma of the non-treated No. 1 on the upper stage and the volume of ¹³CO₂in the plasma on the lower stage, and these determined results are divided (÷) by the volume of the plasma. Table 1 shows that the volume of ¹²CO₂per mass of the found plasma is 860 μg/g and the volume of ¹³CO₂is 7.6 μg/g.

To give another example, the chromatograph of FIG. 33 shows the volume of ¹²CO₂in the plasma of the ¹³CO₂mist-treated No. 1 on the upper stage and the volume of ¹³CO₂in the plasma on the lower stage, and these determined results are divided by the volume of the plasma. Table 1 shows that the volume of ¹²CO₂per mass of the found plasma is 960 (μg/g) and the volume of ¹³CO₂is 59 (μg/g).

Thus, with respect to Table 1, the measured results of ¹²CO₂and ¹³CO₂in the chromatograph of the plasma, heart, liver and muscle of the rats non-treated and ¹³CO₂mist-treated, were measured with the CO₂analytical curve of m/z44, and the determined results were divided with the volume of the plasma, Table 1 shows the volumes of ¹²CO₂and ¹³CO₂per mass of the found plasma.

By the way, the determined results shown in Table 1 are the values calculated by using the CO₂analytical curve of m/z44, and concerning ¹³CO₂, the values contain the natural isotope (m/z45) existing in CO₂derived from respiration. Therefore, Table 2 shows the detected values of ¹³CO₂corrected by deducting the natural isotope (m/z45) existing in CO₂derived from respiration from ¹³CO₂based on the results shown in Table 1.

Determination

The calculating expression at this time is shown by a following formula, since the natural isotopic ratio of CO₂(m/z44:m/z45) is 0.984:0.0113.

¹³CO₂detecting volume(collection value)=¹³CO₂detecting value−¹²CO₂detecting value×0.0113/0.984.

Table 2 shows “less 2.5 μg/g” in the determined lower limits of the detected values of ¹³CO₂of the plasmas, hearts, livers and muscles of the No. 1 and No. 2 rats not having been treated with the carbon dioxide gas mist pressure bath treatment, and this “less 2.5 μg/g” is lower by far than the detected values of ¹³CO₂of the same tissues of the of the No. 1 and No. 2 treated rats.

FIGS. 47 to 52 show the graphs of gathering ¹²CO₂detecting volume and ¹³CO₂detecting volume (correction value) classifying in the samples and the treating ways.

FIG. 47 shows, with the bar graphs, the respective ¹²CO₂detected volumes of the non-treated No. 1, the non-treated No. 2, the ¹³CO₂mist treated No. 1 and the ¹³CO₂mist treated No. 2, classifying the specimens of the plasmas, hearts, livers and muscles. In this graph, if comparing the ¹²CO₂detecting volumes of the non-treatments and the ¹³CO₂mist treatments, it is found that although the detected volumes of ¹²CO₂in the respective tissues show the high tendency in the samples of the CO₂³mist treated specimens, any remarkable difference is not recognized.

FIG. 48 shows, with the bar graphs, in FIG. 47, the respective ¹²CO₂detected volumes of the non-treated No. 1, the non-treated No. 2, the ¹³CO₂mist treated No. 1 and the ¹³CO₂mist treated No. 2, classifying the specimens of the plasmas, hearts, livers and muscles. Also in this graph, any remarkable difference is not recognized.

FIG. 49 shows, with the bar graphs, the respective ¹³CO₂detected volumes (corrected values) of the non-treated No. 1, the non-treated No. 2, the ¹³CO₂mist treated No. 1 and the ¹³CO₂mist treated No. 2, classifying the specimens of the plasmas, hearts, livers and muscles. This graph shows that in the case of the non-treatment, the volume of ¹³CO₂was scarcely detected, and in the case of performing the ¹³CO₂treatment, ¹³CO₂was effectively detected in each of the tissues of the plasmas, hearts, livers and muscles, and shows the carbon dioxide gas mist pressure bath was effectively treated.

FIG. 50 shows, with the bar graphs, in FIG. 49, the respective ¹³CO₂detected volumes of the non-treated No. 1, the non-treated No. 2, the ¹³CO₂mist treated No. 1 and the ¹³CO₂mist treated No. 2, classifying the specimens of the plasmas, hearts, livers and muscles. Also this graph shows that, in the non-treated, the volume of ¹³CO₂is scarcely detected, but in the ¹³CO₂mist treatment, the ¹³CO₂mist is effectively detected in each of the tissues.

FIG. 51 shows, with the bar graphs, respectively the rate of the ¹³CO₂detecting volume (collected value) to each of the detecting volumes of the non-treated No. 1, the non-treated No. 2, the ¹³CO₂treated No. 1 and the ¹³CO₂treated No. 2. This graph shows that, in the non-treated, ¹³CO₂was scarcely detected to the detecting volume of ¹²CO₂. In the case of performing the ¹³CO₂treatment, ¹³CO₂was effectively detected in each of the tissues of the plasmas, hearts, livers and muscles, and shows the carbon dioxide gas mist pressure bath was effectively treated.

FIG. 52 shows, with the bar graph, in FIG. 51, the rate of the detecting volumes (collected value) of ¹³CO₂to the respective detected volumes of the non-treated No. 1, the non-treated No. 2, the ¹³CO₂treated No. 1 and the ¹³CO₂treated No. 2, specifying the non-treatment and the ¹³CO₂mist treatment. It is seen from this graph that, in the non-treated case, ¹³CO₂was scarcely detected with respect to the detecting volume of ¹²CO₂, but if carrying out the ¹³CO₂mist treatment, the ¹³CO₂mist was effectively detected in the tissues of the plasmas, hearts, livers and muscles.

Next, Table 3 arranges the experimented results of the test specimens 1 to 4 of the non-treated rats and the test specimens 1 to 4 of the rats of the ¹³CO₂treatment.

In Table 3, the ratio of the average values of ¹³CO₂and ¹²CO₂detected in the respective tissues of the specimens 1 to 4 of the non-treated groups is approximately 0.01 (for example, in the case of the plasma, 7.15/917.25=0.008) showing almost the same value as in the atmosphere, and on the other hand, the same ratio in the ¹³CO₂treating groups (for example, in the case of the plasma, 49.0/966=0.05) is more than 6 times of the non-treated groups in the plasma, and more than 3 times of the non-treated groups in the hearts, livers and skeletal muscles.

The ratio of the average values of the total CO₂detected in the respective tissues of the specimens 1 to 4 of the non-treated groups to the average values of the total CO₂detected in the respective tissues of the specimens 1 to 4 of the ¹³CO₂treated groups slightly increased in the plasma as 1.10 (015.05/924.4) times, but in the hearts, increased as 1.59 (640.5/402.0) times, and this fact is considered as contributing to acceleration of metabolism function.

The above analyzing results show that, if making the rats a cutaneous respiration of ¹³CO₂by the carbon dioxide gas mist pressure bath treatment by the present invention, ¹³CO₂is effectively distributed in a body organ, and this fact has proved that depending on the carbon dioxide gas mist pressure bath treatment by the present invention, carbon dioxide is taken effectively into the living body.

Thus, by causing the carbon dioxide gas mist to contact the skin and mucous membrane of the living organism with predetermined pressure (above the internal pressure of the living organism), thereby to heighten the concentration of carbon dioxide taken into the blood so that carbon dioxide does not cease to advance till reaching the heart, an ischemic region can be cured and blood vessels of the heart muscle can be expanded to improve conditions of ischemic region.

As having explained in detail, in the present carbon dioxide pressure bath method, the following steps (a) to (d) are continued at least once per day for four weeks, that is, a step (a) of producing a carbon dioxide gas mist by pulverizing and dissolving carbon dioxide gas into a liquid, and forming this liquid into a mist; a step (b) of spraying the carbon dioxide gas mist into a carbon dioxide gas mist-enclosing means for enclosing the living organism in an air tight state, a step (c) of expelling gas existing in the carbon dioxide gas mist-enclosing means into the outside, if necessary in parallel with the step (b), in order to maintain the pressure of gas within the carbon dioxide gas mist-enclosing means at or above a prescribed value being higher than the atmospheric pressure, and a step (d) of continuing such a step of supplying, for at least 20 minutes, the carbon dioxide mist into the carbon dioxide gas mist-enclosing means. Thereby, carbon dioxide is contacted to the skin and mucous membrane of a living organism directly or through clothing, thereby to improve or promote circulation of the blood in the ischemic region, and furthermore to prevent, improve or cure ischemic disease.

INDUSTRIAL APPLICABILITY
