Abstract
The present invention relates to a kind of structural formula is main chain with β (1-3), and β (1-6) is branched lentinan, and it is obtained after by artificial separation massee fruiting bodies.Its molecular-weight average is 55～1,100,000, and contained each component and content thereof are as follows in the per unit quantity:
Glucose 60.7% semi-lactosi 26.7%
Seminose 11.2% pentose 1.4%
The present invention has following advantage compared to existing technology, and biological activity is strong, the curative effect height.Not only can be used for treating immunodeficiency diseases, but also can be used for treating chronic hepatitis, and side effect is little, occurrence rate only is 0.75%.
Description
The present invention relates to a kind of glucan, particularly a kind of lentinan.It utilizes agaric material fungi one Lentinus Edodes fungus to eat sporophore through the perfume (or spice) of inoculation culture to be raw material, to prepare after artificial the separation.
A kind of lentinan of the once public mistake of Japan, its molecular-weight average is 500,000, finds after clinical application, this lentinan has following several side effect: shock, feel sick, vomit, oligoleukocythemia, hemoglobin reduction, and the narrow sensation of throat is arranged.These side effect occurrence rates are 6.8%.From result of treatment, it can only treat tumor disease, does not have extensive result of treatment.
The objective of the invention is to overcome weak point of the prior art, and provide a kind of side effect little, therapeutic domain is wider, not only can treat tumor disease, also can treat the lentinan of some other disease.
The objective of the invention is to realize by following approach.
Lentinan, structural formula is a main chain with β (1-3), β (1-6) is a branch, obtains behind artificial separation mushroom fruiting body, contains glucose, components such as semi-lactosi and seminose, said lentinan molecular-weight average is 550,000～1,100,000.
According to pertinent data, a large amount of evidences, molecular weight is big more, and then viscosity is big more, and it is senior that molecular structure is tending towards more, and the biological activity of lentinan is just strong more.
But molecular weight is too big, and the medicine side reaction has also strengthened, and is difficult for making.
Experiment and clinical verification show that molecular-weight average is 550,000～1,100,000, can take into account these two factors of biological activity and the former reaction of medicine simultaneously.
Purpose of the present invention can also realize by following approach.
Said lentinan molecular-weight average is preferably 70～900,000.
In the one Board Lot lentinan, contained relevant component and content thereof are as follows:
Glucose 55%～65% semi-lactosi 23%～30%
Seminose 8%～13% pentose 1.0%～2.0%
In the one Board Lot lentinan, contained relevant component and content thereof are as follows:
Glucose 60.7% semi-lactosi 26.7%
Seminose 11.2% pentose 1.4%
Said lentinan purity is at least 92%.
Purity is more than 92%, comprises 92% lentinan and can be used as intravenous injection.
Lentinan of the present invention once carried out clinic trial, and its clinic trial situation and result are as follows:
(1) treatment chronic viral hepatitis 216 examples, total effective rate is 84.3%.Double blind control treatment chronic viral hepatitis 144 examples, total effective rate is 80.5%.The III clinical trial phase of this product, treatment chronic viral hepatitis 108 examples, and through near, the long-term follow-up observation of 6 months and 12 months, satisfactory effect.Total effective rate is respectively 85.2%, 86.9% and 88.2%.Press the Chinese medical discrimination somatotype and judge curative effect, better with empty type of liver depression and qi stagnation and blood stasis type curative effect.Lentinus edodes polysaccharide injecta treatment chronic viral hepatitis efficacy consolidation is described.ALT 1 year normalization rate at a specified future date reaches 82.9%.The treatment of HBeAg, negative conversion rate is to be to be 54.8% after 44.7%, 12 month after 46.7%, 6 month after 2 months, has confirmed that this product has the effect of the hepatitis B virus duplication of inhibition.
(2) during the treatment esophageal carcinoma, carcinoma of gastric cardia and cancer of the stomach totally 71 examples, major part are, late tumor, lesion portion is alleviated and the person's of stablizing 53 examples, total effective rate 74.6%.Press the Chinese medical discrimination somatotype and judge curative effect, the esophageal carcinoma is with QI and phlegm stagnating each other type, the stagnant type of blood stasis phlegm; Cancer of the stomach is better with resistance type person's curative effect in liver-stomach disharmony type, spleen-stomach deficiency-cold and the stasis of blood poison.Be favourable lifetime to the prolongation tumour patient, particularly can adopt the old tumour patient that can not tolerate chemotherapeutics, and can alleviate the toxic side effects of chemotherapy.
In 359 examples of clinical use, side effect 3 examples are arranged, fash 2 examples wherein, 1 example uncomfortable in chest, there is mild pain the individual patient injection site, and the side effect occurrence rate is 0.75%.
In sum, the present invention has following advantage compared to existing technology: few side effects, side effect occurrence rate only are 0.75%.The side effect hazard rating is low; Therapeutic domain is wide, not only can be used for treating kinds of tumors diseases such as the esophageal carcinoma, carcinoma of gastric cardia and cancer of the stomach, and can be used for the treatment of chronic viral hepatitis, and biological activity is strong simultaneously, and result of treatment is good, the total effective rate height.
Below we carry out more detailed description to the present invention in conjunction with the embodiments.
