20220265754
The present invention relates to methods of improving diseases using a traditional Chinese medicine polysaccharide and a bacterial composition thereof, and more particularly to methods of improving chronic obstructive pulmonary disease and obesity using Ganoderma lucidum (GL) polysaccharide, Dendrobium huoshanense (DH) polysaccharide, Hirsutella sinensis (HSM) polysaccharide, or any combination thereof.
Due to the limited number of digestive enzymes encoded by the human genome, polysaccharides in ingested foods are often not fully digested in the small intestine before reaching the rectum. Microbes in the gut can decompose the polysaccharides through glycolysis, and produce many short-chain oligosaccharides with different lengths, structures, and branching numbers, some of which can even act as prebiotics to promote gut microbes growth. The shorter polysaccharides can be further digested into monosaccharides such as glucose, arabinose, or rhamnose, which can also be used to promote the growth of intestinal microorganisms. The monosaccharides can also be further metabolized into short-chain fatty acids, lactic acid, hydrogen and other metabolites in the intestine, which may directly affect the physiological functions of the hosts.
However, since different types of bacteria have different carbohydrate-active enzymes (CAZymes), the extent to which polysaccharides in food are digested and utilized by individual gut bacteria, and the impact of the resulting metabolites on host physiology, and even on the effects of different diseases needs further research.
One objective of the present invention is to provide a method of ameliorating chronic obstructive pulmonary disease (COPD), comprising administering to a subject in need thereof a composition containing a traditional Chinese medicine polysaccharide, wherein the traditional Chinese medicine polysaccharide is selected from a group consisting of Ganoderma lucidum polysaccharide, Dendrobium huoshanense polysaccharide, Hirsutella sinensis polysaccharide, and any combination thereof.
In one embodiment of the present invention, the Ganoderma lucidum polysaccharide is from a water extract of Ganoderma lucidum, the Dendrobium huoshanense polysaccharide is from a water extract of Dendrobium huoshanense, and the Hirsutella sinensis polysaccharide is from a water extract of Hirsutella sinensis.
In the embodiment of the present invention, an effective amount of the traditional Chinese medicine polysaccharide is at least twice a week for the subject in need thereof with at least 25 mg/kg each time.
The further objective of the present invention is to provide a method of ameliorating chronic obstructive pulmonary disease, comprising administering to a subject in need thereof a bacterial composition containing a bacterial consortium and the traditional Chinese medicine polysaccharide above.

In other embodiment of the present invention, the bacterial composition reduces body weight gain of the subject in need thereof; and the bacterial composition reduces adipose tissue weight, triglyceride, total cholesterol, and/or fasting glucose of the subject in need thereof.
In the embodiments of the present invention, an effective amount of the bacterial composition is at least twice a week for the subject in need thereof with the bacterial composition containing at least 3×1010 CFU/kg of the bacterial consortium and at least 25 mg/kg of the bacterial composition each time.
In the embodiments of the present invention, the composition or the bacterial composition further comprises a pharmaceutically acceptable excipient, carrier, adjuvant, or food additive.
In the embodiments of the present invention, the composition or the bacterial composition is in the form of a spray, a solution, a semi-solid preparation, a solid preparation, a gelatin capsule, a soft capsule, a tablet, a chewing gum, or a freeze-dried powder preparation.

First, a mixture (50 g/L) was prepared by mixing 500 g of dried Ganoderma lucidum mycelium into 10 liters of distilled water using a 20 liter-stirred tank reactor. The 5.0% (w/v) mixture was agitated at a speed of 150 rpm for 30 mm at 121° C. The mixture was then centrifuged to remove insoluble material and to obtain a Ganoderma lucidum water extract. The Ganoderma lucidum water extract was concentrated to a final volume of 2.5 L using a vacuum concentrator. The concentrated Ganoderma lucidum water extract was sterilized at high temperature and pressure for 20 minutes in an autoclave to obtain a 20% (w/v) concentrated Ganoderma lucidum water extract and stored at 4° C.
1.1.2 Preparation of the Ganoderma lucidum Crude Polysaccharide Extract
Next, 120 mL of the 20% (w/v) concentrated Ganoderma lucidum water extract was mixed with 5 volumes (600 mL) of 95% ethanol and incubated at 4° C. for 16 hours to induce the precipitation of crude polysaccharide. The mixture was centrifuged to obtain a supernatant and a precipitate (pellet). The supernatant was removed, while 120 mL of 70% ice-cold ethanol was used to wash and re-suspend the precipitate to obtain a mixture. Repeat such washing-resuspension-centrifugation steps three times and the mixtures were combined. The crude polysaccharide precipitate (pellet) was dissolved into 1,000 mL of distilled water and concentrated to a final volume of 700 mL using a vacuum concentrator in order to remove residual ethanol. Finally, distilled water was added to obtain a Ganoderma lucidum crude polysaccharide extract with a final volume of 2,400 mL.
1.1.3 Fractionation of the Ganoderma lucidum Crude Polysaccharide Extract
2,400 mL of the Ganoderma lucidum crude polysaccharide extract was placed into a beaker, followed by incubation at 50° C. into a water bath. The Ganoderma lucidum crude polysaccharide extract was fractionated by using a tangential flow filtration (TFF) system (KrosFlo, Spectrum Laboratories) with a 0.2-nm hollow fiber membrane (1,500 cm2, polyethersulfone, PES). The trans-membrane pressure (TMP) was set at 15-16 psi. 600 mL of distilled water was added into the retentate during filtration when the retentate remained from 800 to 1000 mL for continuing the filtration. Addition of water was repeated two times (a total of 1,800 mL distilled water was added to the retentate). 650 mL of sub-fraction G1-1 and 3,600 mL of filtrate were obtained this way.
The above-mentioned 3,600 mL of 0.2-μm filtrate was placed into a beaker and incubated at 50° C. in a water bath.

1.2 Preparation of the Dendrobium huoshanense Polysaccharides (DHPS)
First, the freeze-dried 2000 g of Dendrobium huoshanense were pulverized and defatted twice with petroleum ether in Soxhlet extractor. The dregs were successively extracted thrice with boiling distilled-water, with each time for 0.5 hour. The Dendrobium huoshanense water extracts were combined and followed by centrifuging at 8000 rpm for 10 minutes at 4° C. The supernatant was subsequently concentrated in a rotary evaporator at 60° C. to small volumes under reduced pressure, and precipitated with four volumes of anhydrous ethanol for overnight. The precipitate was collected by centrifugation and washed three times with acetone. Afterwards, the precipitate was re-suspended in distilled-water and de-proteinized using the Sevag reagent. The aqueous fraction was precipitated with anhydrous ethanol at the ratio of 1:4 (v:v) for 24 hours at 4° C. The resulting precipitate was harvested by centrifugation, dialysis and lyophilization to produce polysaccharides which was the Dendrobium huoshanense Polysaccharides (DHPS) of the present invention.
