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:
Disclosed herein are an anti-tumor substance obtained by bonding an anti-tumor agent to human immunoglobulin, and a process for producing the same.
摘要:
Disclosed herein is a pharmaceutical composition in dosage unit form, which comprises a dosage effective for treating nephritic disease of a compound of 24,25-dihydroxycholecalciferol as an active ingredient and a pharmaceutically acceptable carrier.
摘要:
Polysaccharides having antitumor and other useful pharmacological activities and a process for preparing such polysaccharides are disclosed. These polysaccharides are characterized by .alpha.-bonding of the saccharide component and can be produced from the extracts obtained by the extraction of a basidiomycetous fungus belonging to the genus Coriolus or cultures thereof with an aqueous solvent.
摘要:
Disclosed is a novel pharmaceutical composition having antitumor activity without causing pyrexia and anaphylaxis formed by an amido bonding between an antibody obtained by the purification of the antibody to tumor antigen via affinity-chromatography and an antitumor substance.
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:
When a dikaryotic mycelium of Coriolus versicolor (Fr.) Quel. (a species of fungi belonging to the genus Coriolus of Polyporaceae) is subjected to a mechanical treatment such as grinding or shearing in a liquid medium, or when such mycelium is subjected to submerged culture while undergoing mechanical treatment, there is produced a monokaryotic mycelium which is different from the dikaryotic mycelium in morphological and physiological characteristics. The thus obtained monokaryotic mycelium is a novel product and characterized by its extremely high propagation rate as compared with the known dikaryotic mycelium. Also, the substance extracted from the culture of the mycelium has excellent physiological activities.
摘要:
Disclosed is a pharmaceutical composition in dosage unit form which comprises a dosage effective for the treatment of pains and pyrexia, hypertension, hypotension, hyperlipemia, inflammatory diseases or diseases due to the functional accentuation of thrombocytes of a compound of 24,25-dihydroxycholecalciferol and a pharmaceutical acceptable carrier or diluent therefor.
摘要:
Disclosed herein is a method for examining cells, comprising subjecting the cells to an antigen-antibody reaction treatment, then measuring a pattern of the electrophoretic mobility of the cells and comparing the electrophoretic property of the cells under examination with the electrophoretic property of standard cells.
摘要:
Disclosed herein is a method for preventing senescence and increasing bone mass namely, bone volume and bone strength which method comprises administering 24,25-dihydroxy cholecalciferol in a pharmaceutically effective amount, and also use of 24,25-dihydroxy cholecalciferol for preparing anti-senescent compositions and compositions for increasing bone mass.
