Abstract

Abstract Disclosed herein is a pharmaceutical composition having antirheumatic activity, antithrombotic activity, analgetic activity, antipyretic activity, anti-hyperlipemic activity and anti-inflammatory activity and activities of reducing the level of blood sugar, raising the coronary blood flow, improving the capability of deformation of erythrocytes, reducing the blood pressure, ameliorating proteinuria and proteinemia and regulating production or metabolism of prostaglandins in a mammal in dosage unit form, which comprises a dosage effective to produce said activities of a glycoprotein having a molecular weight of 5000 to 300000 as determined by ultracentrifugal method and about 18 to 38% by weight of proteins, produced by culturing a basidiomycetous fungal species belonging to the genus Coriolus, extracting the thus proliferated mycelia or fruit bodies with hot water or aqueous alkali solution and removing low molecular weight substances having a molecular weight of less than 5000 from the extract.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 95 words
A method for raising a level of low density lipoprotein receptor in a patient's body, which comprises: administering to a human suffering from hyperlipemia a therapeutically effective amount of glycoprotein having a molecular weight of 5,000 to 300,000 as determined by ultracentrifugation and is to 38% by weight of proteins, produced by culturing a basidiomycetous fungal species belonging to the genus Coriolus; extracting the thus proliferated mycelia or fruit bodies with hot water or an aqueous alkaline solution; and removing low molecular weight substances having a molecular weight of less than 5,000 from the extract.
Claim 2
Independent Claim 95 words
A method for raising a level of low density lipoprotein receptor in a patient's body, which comprises: administering to a human suffering from hyperlipemia a therapeutically effective amount of glycoprotein having a molecular weight of 5,000 to 300,000 as determined by ultracentrifugation and is to 38% by weight of proteins, produced by culturing a basidiomycetous fungal species belonging to the genus Coriolus; extracting the thus proliferated mycelia or fruit bodies with hot water or an aqueous alkaline solution; and removing low molecular weight substances having a molecular weight of less than 5,000 from the extract.
Claim 3
Dependent Claim 25 words
The method of claim 1, wherein said fungal species of the genus Coriolus is the strain Coriolus versicolor (Fr.) Quel. identified by ATCC No. 20547.
