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 method for the treatment of hyperglycemia, hyperlipemia, inflammatory diseases, pains due to the accentuation of central nerve, pyrexia due to the accentuation of central nerve or tumor, which comprises administering to a patient suffering therefrom a pharmaceutically effective amount of p-aminobenzoic acid-N-L-rhamnoside or a pharmaceutically acceptable salt thereof.
摘要:
Disclosed is a novel pharmaceutical composition having antitumor (anti-cancer) activity without causing pyrexia and anaphylaxis, formed by an amide bonding between an antibody obtained by the purification of the antibody to tumor (cancer) antigen via affinity-chromatography and an antitumor substance (anti-cancer drug).
