1. Field of the Invention
The present invention relates to methods for treating or improving rheumatism and pain and its apparatus therefor.
In more detail, it relates to non-pharmacological methods for treating or improving rheumatism and pain caused by the rheumatism, tumor, spinal damage, and the like by exposure of electric fields, and its apparatus therefor.
2. Description of the Prior Art
Rheumatism is disease causing pain, swelling, inflammation to joints of a whole body including limbs, and as the state of the disease develops, it causes deformation or dysfunction of the joints.
For treating rheumatism, various kinds of, medications have been administered. Steroidal therapeutic medication, one of the typical medications, has a drawback of strong side effects. For example, although a steroidal therapeutic medication with fewer side effects as disclosed in a patent document 1 has been developed, all the side effects cannot be eliminated. Even when non steroidal therapeutic medications are administered, side effects might be caused to digestive systems and the like, and this has been the problem which remains unsolved.
Patent Document 1: Japan Unexamined laid-open patent publication 2002-539167
As the state of the disease of rheumatism further develops, an operation for removing the synovial membrane of the inflamed joint is required, and when it further develops, an operation of replacing the deformed joint with an artificial one is sometimes performed. Both operations are heavy burden for patients, especially for aged patients.
Not only human beings but also other mammalian animals in particular, pet animals such as dogs, cats, and the like can develop rheumatism. Therefore, owners for pet animals have also longed for effective methods for treating rheumatism.
In addition, not only rheumatism but also chronic pain caused by tumor, spinal damage, and the like are intolerable for patients and thus, effective methods for treating such disease have also been longed for.
The object of the present invention is to provide methods for treating rheumatism and pain caused by rheumatism, tumor, spinal damage, and the like by non-pharmacological methods, and its apparatus.
The present invention achieves the above mentioned object by which rheumatism of mammalian animals is treated or improved non-pharmacologically, and in which electric fields are exposed to whole or a part of mammalian animals with electrodes in a non-contact state with said mammalian animals.
Although detailed mechanisms have not been found out, it is considered that by exposing electric fields, biosynthetic pathways of beta-endorphin and decomposition pathways of ACTH in hypophysis, particularly in intermediate lobe are activated directly or indirectly thereby treating and improving symptoms of rheumatism.
In addition, in treating rheumatism, affected areas of the rheumatism are improved organically by exposing electric fields at least to the affected areas.
It is preferable that the electric fields are the extremely low frequency AC electric fields and it is more preferable that the AC electric fields are overlapped with DC electric fields.
It is preferable that regarding the exposure of the electric fields, the electric fields are exposed only for a certain period of time in a day, repeating it everyday or with certain intervals, and it is more preferable that the frequency of the exposure is more than once a week. By this, the symptom is gradually improved.
Although available to all the species as long as they are mammalian animals, pet animals such as dogs, cats, and the like are particularly available. Further, the method can treat and improve human beings.
Also, the present invention relates to a treating and improving apparatus which treats or improves rheumatism of mammalian animals, wherein said apparatus is provided with a pair of electrodes which can expose electric fields to a whole body or a part including rheumatism-affected part of mammalian animals and a power source which applies voltage to said pair of electrodes.
Another embodiment of the present invention includes an apparatus by which the affected areas can be improved organically by exposing the electric fields at least to the affected areas of rheumatism. It relates to the apparatus in which the above mentioned synthetic paths and decomposition paths of hormones are activated by exposing the electric fields at least to the diseased area thereby treating and improving the symptoms of rheumatism.
It is preferable that the electric fields generated by the apparatus of the present invention are the extremely low frequency AC electric fields and it is more preferable that the AC electric fields are overlapped with DC electric fields. It is preferable that the present apparatus of the present invention is further provided with a power controller by which at least one among applied voltage, frequency, and exposure time is controllable depending on the size or symptom of mammalian animals to be treated.
The apparatus related to the present invention is the apparatus effective for treating or improving rheumatism and it is particularly effective for pet animals such as dogs, cats, and the like, and human beings although species of mammalian animals are not specifically limited.
Another embodiment of the present invention includes an apparatus for treating or improving rheumatism of mammalian animals and pain caused by rheumatism, tumor, spinal damage, and the like, thereby preparing the apparatus for treating or improving provided with a pair of electrodes in which electric fields can be exposed to a whole body or a part thereof including affected area of said mammalian animals and a power source applying voltage to said pair of electrodes.
It is preferable that the electric fields generated by the present apparatus are the extremely low frequency AC electric fields and it is more preferable that the AC electric fields are overlapped with DC electric fields.
It is preferable that the present apparatus of the present invention is further provided with a power controller by which at least one among applied voltage, frequency, and exposure time is controllable depending on the size or symptom of mammalian animals to be treated.
The apparatus related to the present invention is the apparatus effective for treating or improving rheumatism and pain caused by rheumatism, tumor, and spinal damage and it is particularly effective for pet animals such as dogs, cats, and the like, and human beings although species of mammalian animals are not specifically limited.
According to the method and the apparatus of the present invention, other than rheumatism of mammalian animals, in particular, that of pet animals such as dogs, cats, and the like, and human beings, pain caused by rheumatism, tumor, and spinal damage can be treated or improved. That is, it is considered that by exposing electric fields, synthetic paths of beta-endorphin and decomposition paths of ACTH are indirectly or directly activated in hypophysis, in particular, in intermediate lobe, thereby treating or improving symptoms by pain.
Hereinafter, referring to the drawings, embodiments of the present invention are explained.
A mammalian animal suffering from pain is placed in an electric field exposure cage 3. When high voltage generated from a high voltage generating unit 1 was applied to a pair of electrodes 2a and 2b, electric fields are generated in an electric field exposure cage 3 and the electric field is exposed to the mammalian animal. Further, the electric field is exposed to the mammalian animal in the cage 3 without contacting any of electrode 2a or 2b.
Although the voltage applied to the electrodes 2a and 2b may be either of AC or DC, it is preferable that the electric fields are the extremely low frequency AC electric fields and it is more preferable that the AC electric fields are overlapped with DC electric fields. Further, the high voltage generating unit 1 includes a controller (not illustrated) which controls frequency, applied voltage, exposure time, and the like.
In addition, by exposing the electric fields for a certain period of time a day and repeating it every day, the treating and improving effect is gradually shown.
Although the relationship between electric field exposure and the effect of treating pain is not unraveled, it is assumed that, as mentioned above, synthesis of beta-endorphin and decomposition of ACTH are promoted, thereby showing the effect of treating (improving) pain.
In order to acknowledge the treating and improving effect of pain by the present invention, the treatment experiments were conducted on dogs as subject animals.
(Treating and Improving Apparatus)
A treating and improving apparatus is composed of two major parts, namely a high voltage generating unit 1 (
(Distribution of Electric Fields)
In order to measure distribution in an electric field exposure cage 3, the electric field strength of a bottom space of the cage 3 was measured.
The electric field strength of 66 points at the bottom part of the cage 3 shown in
From the result of
(Subject Animals)
Five male beagle dogs were obtained from Charles Rivers Laboratories as normal animals and further, total of 10 dogs composed of those with tumor (n=5) and those with spinal damage (n=5) were selected from foreign animals brought to Nihon University animal hospital as subject animals.
(Experimental Schedule)
Experiments were conducted at Nihon University animal hospital. Electric fields were exposed to subject animals (dogs) separately, 2 hours a day and over one week. One electric field exposure is defined as one session, and in every session, each subject animal was transferred from the usual cage to the electric field exposure cage 3 and the electric fields were exposed to the animals. In order to avoid imbalanced data caused by change in hormone secretion by circadian rhythm of subject animals, all the experiments were conducted in the time zone from 14:00 to 18:00.
All the animals during the experiments were kept without any other clinical treatment. All the experiments using subject animals were conducted under informed consent.
(Plasma Parameter)
ACTH (adrenocorticotropic hormone) induced by stress and beta-endorphin having morphine-like tranquilizing effect were measured.
Before and after the electric field exposure, from the vessel of forelimb of subject animals, blood samples were collected by injecting heparin. Further, 500 g of the blood samples were centrifugalized for 15 minutes at a temperature of 4° C. thereby preparing plasma samples. Plasma samples were preserved at a temperature of −70° C. until ACTH and beta-endorphin were measured. ACTH values in the plasma were measured by ACTH radioimmunoassay kit (ACTH IRMA, manufactured by Mitsubishi Chemical Corporation, Tokyo, Japan) and a gamma counter (Auto-Gamma 5530 Gamma Counting System, manufactured by Packard Instrument Corporation). Beta-endorphin values in the plasma were measured by a commercially available kit (manufactured by Mitsubishi Chemical Corporation). These measurements of hormones were conducted at Institute for Health Sciences (Kanagawa, Japan) which is an outside organization.
(Statistical Analysis)
Experimental results are shown by mean ± standard error (S.E.) of mean. Statistical significance of difference between two groups and daily changes were calculated by analysis of variance. The difference between two groups were calculated by a student's test or analysis of variance and the significance was defined to be P<0.05. All the computations for the statistical analysis were carried out by using MS-EXCEL® Japanese Edition (Microsoft Office software: Ver.9.0.1, Microsoft Japan Inc).
The experiments were conducted based on the guideline on “The Care and Use of Research Animals” published by Panapharm Laboratories.
(Experimental Result)
Normal Subject Animals
As shown in
On the other hand, as shown in
Subject Animals with Tumor
As shown in
Subject Animals with Spinal Damage
As shown in
Further, as shown in
The heretofore mentioned results suggest that electric field exposure does not seriously affect stress hormone values (ACTH values and beta-endorphin values) of normal animals.
In the subject animals with spinal damage, the ACTH values after the session went down compared with the values before the session, which shows that the stress reaction related to pain sense has been tranquilized by electric fields. Further, the ACTH values before the session show remarkable degradation depending on the days. This at least shows that the stress caused by pain becomes tranquilized by the electric field treatment day by day.
Beta-endorphin values after the session in the subject animals suffering from pain caused by tumor or spinal damage dramatically rose. It is considered that the central pain-tranquilizing system of the subject animals has been up-regulated through the unknown pathways by the electric field.
Stress-related hormone values such as ACTH, beta-endorphin and the like of normal animals subject to extremely low electric field exposure are maintained without any influence. However, in the subject animals suffering from pain, the presence of the electric fields is considered to somewhat affect stress-related endocrine system. That is, it is well known that ACTH and beta-endorphin generated and secreted from proopiomelanocortin are treated at hypophysis and that ACTH is synthesized at anterior lobe and intermediate lobe, but is decomposed only at intermediate lobe. On the other hand, it is publicly known that although beta-endorphin is also synthesized in anterior lobe and intermediate lobe, the beta-endorphin is more quickly decomposed in intermediate lobe than in anterior lobe. Thus, it is considered that the synthetic pathways of beta-endorphin and the decomposition pathways of ACTH at hypophysis particularly at intermediate lobe are activated indirectly or non-indirectly.
(Treating and Improving Apparatus)
The same apparatus as in Example 1 was used as a treating and improving apparatus.
(Subject Animal)
A subject animal is a dog that visited Nihon University animal hospital after diagnosed as chronic rheumatic arthritis by a veterinarian in general practice. The breed of the dog was a female Shetland sheep dog, 10 years and 1 month. The dog visited the hospital with the major complaint of ananastasia. The symptom spread from lameness in a hind limb to lameness in a forelimb. The case was suspected to be early-phase rheumatic arthritis (eRA) and the later mentioned CRP value was measured. As a result, the CRP value showed high level of 2.4 mg/dl compared with a normal state.
(Plasma Parameter)
CRP (C-reactive protein) is one of acute-phase proteins which is not detected in normal blood and therefore, it is useful as an inflammatory marker for human beings. This value indicates the presence of inflammatory disease belonging to these diseases such as rheumatic joint disease and the like and serves to judge disease progress.
It is said that positiveness of the CRP test goes abreast of intensity of disease symptom and in particular, in rheumatic disease with seesawing disease progression, exacerbation and lowering thereof can be judged by repeating examination. CRP positive is a diagnostic criterium of early-phase rheumatic arthritis in Japan College of Rheumatology and the relationship between the CRP positive and chronic rheumatic arthritis is suggested.
Considering that the CRP value can be used as judgment criteria of disease progression in dogs as well, the CRP value before and after the electric field exposure was measured. In a CRP measuring method, blood sample was obtained from the forelimb artery of a subject animal by conventional means, followed by separating blood plasma and using it for examination. A dog CRP concentration measuring apparatus (manufactured by Arrows Co., Ltd.) was used as a measuring apparatus and Dog CRP measuring reagent kit (manufactured by Arrows Co., Ltd.) was used as a kit.
(Experimental Results)
Normal Subject Animals
In order to compare with the case of chronic rheumatic arthritis, 8 normal beagle dogs (4 male dogs and 4 female dogs) were used to measure the CRP values. As shown in table 1, the average value for males was 0.18 mg/dl, the average value for females was 0.45 mg/dl, the average value of females was relatively high, and the average for both was 0.31 mg/dl. The average value was substantially the same as the already reported result of CRP measurement.
Subject animal with chronic rheumatic arthritis
CRP values
Subject animals with chronic rheumatic arthritis were treated by the electric field exposure. In the treatment, the electric field was exposed for two hours. The result is shown in
It is observed that before and after the electric field exposure, there are changes in the CRP value. In addition, from November 16th, the subject animal was treated with shorter intervals.
Next, since the CRP value decreased showing the effect of the electric field exposure, and since greater effect could be expected in serial electric field exposure everyday than the electric field exposure once a week, the subject animal was treated by the electric field exposure everyday.
Beta-Endorphin Value
Other than the CRP value, for the purpose of monitoring the state of the subject animal at the time of conducting electric field exposure, the beta-endorphin value in the blood was measured. Beta-endorphin is peptide hormone secreted from anterior lobe and intermediate lobe of hypophysis and is a substance with morphine-like tranquilizing effect. Beta-endorphin is said to be secreted when feeling comfortable or feeling happy and the average value for dogs is said to be 4 to 5 pg/ml.
For reference, when the beta-endorphin value of normal subject animal was measured, the value ranged from 8 to 15 pg/ml.
MRI Observation
MRI imaging was conducted to a left elbow joint of the subject animal. When the T2 weighted images of MRI were compared before and after the electric field exposure, partial necrosis was acknowledged before the electric field exposure (
As heretofore mentioned, summing up the changes before and after the treatment of subject animals suffering from chronic rheumatic arthritis, the CRP value that was higher than the normal value before the treatment lowered after the treatment. That is, it is said that by the lowering of the CRP value, the symptoms of rheumatism was improved. As shown in the MRI images in
(Treating and Improving Apparatus)
The same apparatus as used in Examples 1 and 2 was used as a treating and improving apparatus.
(Subject Animals)
Subject animals are 12 dogs suffering from chronic rheumatic arthritis that visited the Nihon University animal hospital.
(Experimental Result)
CRP Value
Subject animals suffering from chronic rheumatic arthritis were treated by the electric field exposure. In the treatment, the electric field exposure was conducted for 2 hours a week. The CRP value was measured by the same method as in the Example 2 before and after the exposure. The CRP value before and after the exposure each week is shown in table 2. From the table, it is found that in any subject animal, the CRP value decreased by the electric field exposure and the remarkable effect can be obtained by repeating exposure.
Although the explanation was made with regard to the Examples to dogs, by preparing a pair of electrodes with appropriate size and by arranging them with appropriate intervals, other mammalian animals such as cats and the like and human beings and the like can be treated and improved.
When the mammalian animals are human beings, as shown in
By applying voltage from a high voltage generating unit 11 to a pair of electrodes 12a and 12b, electric field is generated between a pair of electrodes 12. By the disposition of electrodes 12, electric field can be exposed not only to affected areas of rheumatism or those of pain, but also to a foot portion from a head portion of a human H. In addition, a high voltage generating unit 11 includes a controller (not illustrated) and the controller can control frequency, applied voltage, exposure time, and the like. Depending on height or weight of a human being H, these values can be controlled.
According to the method and the apparatus of the present invention, rheumatism of mammalian animals including pet animals such as dogs, cats, and the like and human beings can be treated or improved by a non-pharmacological method. In addition, pain caused by rheumatism, tumorpinal damage and the like can also be treated or improved by the non-pharmacological method.
