摘要:
Polysaccharides are produced by purifying a liquid extract of a mycelium of a strain of fungus species belonging to the class Basidiomycetes or the filtered broth of a cultured medium in which a mycelium of a selected strain of Basidiomycetes has been incubated; the polysaccharides exhibiting an anticarcinogenic activity in mice.
摘要:
A method of restoring the immune response of a patient having a lowered immune response level is provided, in which the patient is given an effective amount of certain nitrogen-containing polysaccharides derived from Coriolus versicolor (Fr.) Quel, where the polymer units having a molecular weight of below about 5,000 have been removed therefrom.
摘要:
Disclosed is nitrogen-containing polysaccharide substantially free of units having a molecular weight below about 5,000, said nitrogen-containing polysaccharide having been extracted from Coriolus versicolor (Fr.) Quel., substantially all polymer units having a molecular weight below about 5,000 having been removed therefrom, which exhibits antitumor and immunological activity.
摘要:
The fungi belonging to the Coriolus genus is first extracted with water or a dilute alkaline solution and then further extracted stepwise by using alkaline solutions with gradually increased concentrations to obtain a nitrogen-containing polysaccharide having an anti-tumor activity in a high yield.
摘要:
The fungi belonging to the Coriolus genus are extracted by using a dilute alkaline solution having a concentration within a certain specified range whereby the low molecular weight substances with molecular weight of less than 5,000 are obtained in there extract solution. These low molecular weight substances are separated from the extract solution to obtain a nitrogen-containing polysaccharide having excellent anti-tumor activity.
摘要:
Disclosed is a pharmaceutical composition containing an aminobenzoic acid derivative as an active ingredient represented by the following general formula: ##STR1## wherein .sup.1 R donotes one member selected from the group consisting of the residual groups formed by removing OH at 1(alpha) or 1(beta) position from arabinose, glucose, galactose and mannose, or a pharmaceutically acceptable salt thereof.
