Background technology
Immunologic function is not only the first line of defence that body is defendd external source of disease invasion, also be that self or the kind mutant that produced by environmental stimuli are discerned and killed, eliminate in the body " impurity ", guarantee " bodyguard " of the normal and balance and stability of body cell function.Immunologic function that a variety of causes causes reduces and is common in not only that the resistance to antibacterial and viral infection descends under the sub-health state, also is the major reason that causes cancer and some chronic disease accompanying infection diseases.Therefore, correct the immunologic function of imbalance, for diseases prevention, cure the disease, improve people and be significant quality of life.
Immunostimulant such as bacillus calmette-guerin vaccine, levamisole and interleukin-2, interferon and thymosin etc. commonly used at present, or use inconvenience, or untoward reaction is serious, has all limited their application.
Chinese medicine is accumulating rich experience aspect the adjusting human body self function, and finds that plurality of Chinese has stronger immunomodulating and immune enhancing function in the Chinese medicine practice, as Ganoderma, Radix Ginseng, the Radix Astragali etc.Modern pharmacology studies have shown that polysaccharide is to regulate immunity of organism balance, the main functional component of performance immunoregulation effect in the above-mentioned Chinese medicine.Active polysaccharide can be by activated lymphocyte and macrophage, the various cytokines of promotion (interferon, interleukin, tumor necrosis factor) generation, the approach such as activity that activate reticuloendothelial system and strengthen natural killer cell regulate body's immunological function.And toxicologic study shows that the natural polysaccharide composition does not have toxicity, and is safe in utilization, is that the prepared health promoting product of raw material can be taken for a long time for general crowd with it.
Ganoderma, broadly comprise any among the polypor Ganoderma of kind surplus in the of known 180, be meant Ganoderma lucidum (Leyss. Ex Fr.) Karst. Ganoderma Lucidum (the Leyss ex Fr.) Karst. or the Ganoderma Ganoderma sinensiZhao that are recorded for Pharmacopoeia of People's Republic of China (version was two ones in 2005) narrowly, the dry sporophore of Xu et Zhang.Contained according to pharmacopeia, the Ganoderma nature and flavor are sweet, and are flat; Invigorating QI and tranquilization is arranged, and the effect of relieving cough and asthma can be controlled dizzy sleeplessness, shortness of breath and palpitation, asthenia cough with asthma.Ganoderma is listed in top grade in China's pharmacy works Shennong's Herbal the earliest, and it also is one of U.S.'s " medical herbs pharmacopeia " 10 kinds of Chinese herbal medicine of only including.Modern scientific research shows that Ganoderma contains multiple bioactive substances such as polysaccharide, several amino acids, steroid class, triterpenes, alkaloid, organic acid, mannitol, and contains various trace elements.Its contained ganoderan is considered to the main component of its pharmacologically active, and the Pharmacopoeia of the People's Republic of China (version was an one in 2005) is with the control criterion of ganoderan as the Ganoderma quality.At present with the pharmacology activity research of the ganoderan that from Ganoderma lucidum (Leyss. Ex Fr.) Karst., obtains at most, the most deep, find that ganoderan has effects such as antitumor, human body immunity improving power and hypoxia-bearing capability (referring to World Science technology-Chinese medicine modernization 6 (2): 57-62; 2004), the polysaccharide that derives from other kinds of Ganoderma has similar pharmacologically active to Ganoderma lucidum (Leyss. Ex Fr.) Karst..Ganoderan does not have direct kill capability to tumor cell, its antitumor action is relevant with its adjusting body power, find that it is mainly by promoting the T lymphopoiesis, the B cell that improves mice produces the ability of specific antibody, promote the generation of the factors such as interleukin, interferon and TNF-α, and enhancing human body immunity functions such as the phagocytic function of enhancing mouse macrophage and raising NKT (NK) cytoactive.
The production of ganoderan is outside the raw material divided by wild or tame Ganoderma sporophore, also can extract from the mycelium of Ganderma lucidum submerged fermentation or fermentation liquid.By studies show that ganoderan is formed by glucose, fructose in Ganoderma sporophore, the mycelium, and these two kinds of monosaccharide are identical with mol ratio in the mycelium polysaccharides at sporophore, provide molecular basis for the ganoderan in different genera source has similar biologic activity.Long because of the artificial culture sporophore production cycle, cost is high, the much more existing deep fermentation methods that adopt are produced ganoderans (referring to the research of Ganoderma intracellular polysaccharide superior strain G7 deep layer fermenting process, edible fungi of china 23 (6): 36-39; 2004).The ganoderan molecular weight except that the sub-fraction micromolecular polysaccharide, scarcely is dissolved in alcohol in high concentration, and is dissolved in hot water from hundreds of to hundreds thousand of, therefore is applicable to water extraction-alcohol precipitation technology extraction.
The Grifola frondosa (Grif ola f rondosa (Dicks, ex Fr) S.F.Gray) that the present invention uses has another name called hen of the woods, thousand Buddhist bacterium, Semen Castaneae mushroom, YUNTAN, Flos Nelumbinis bacterium etc. for Polyporaceae tree flower Pseudomonas fungus.Its sporophore fragrant odour, delicious in taste, and be rich in multivitamin, mineral and bioactive substance, be the dual-purpose dual-purpose fungus of a kind of food, medicine of preciousness.Modern pharmacology studies have shown that its contained polysaccharide component has antitumor, regulates multiple pharmacological activities such as immunity and antiviral (referring to research and development of natural products 15 (4): 364-368; 2003).The production of grifolan is outside the raw material divided by tame sporophore, also can extract from the mycelium of Grifolas frondosa germ submerged fermentation or fermentation liquid.
This patent invention is discovered, with Ganoderma and Grifola frondosa is raw material, the extract that is rich in ganoderan and is rich in grifolan that obtains all has the effect of numeration of leukocyte of the mice of the injection cyclophosphamide that raises, and it is oral by the compound preparation that above-mentioned two kinds of polysaccharide components are formed, under the prerequisite that reduces the total polysaccharides consumption, can not only increase the numeration of leukocyte level of the mice of injection cyclophosphamide, and can reverse the reduction of injecting cyclophosphamide mouse thymus exponential sum spleen index, and can increase the phagocytic function of normal mouse macrophage.Safety testing studies show that the above compound preparation of the present invention of mice oral 20g/kg every day does not have any untoward reaction, and compound preparation promptly of the present invention belongs to innocuous substance, is fit to general crowd and takes in a large number for a long time.
