    摘要: Disialosyl Le.sup.a (IV.sup.3 NeuAcIII.sup.6 NeuAcIII.sup.4 FucLc.sub.4), a novel human cancer-associated fucoganglioside that is highly immunogenic. Also, a hybridoma cell line (ATCC No. HB 8861) secreting a monoclonal IgG3 antibody (FH7) directed to disialosyl Le.sup.a. The disialosyl Le.sup.a antigen was detected in various cancer tissues and their cell lines but was absent in various normal tissues and blood cells. Sera of patients with various cancers, particularly early cases of colonic and gastric cancers, showed an elevated disialosyl Le.sup.a antigen level, which subsequently decreased after surgical tumor removal.

    摘要: A method for preparing de-N-acylated forms of an N-acyl sugar-containing glycosphingolipid and lyso forms of glycosphingolipid comprising hydrolyzing the glycosphingolipids under mild alkaline conditions such that the N-acyl group of the sugar moiety is preferentially hydrolyzed. Substantially pure gangliosides containing de-N-acetyl-sialic acid isolated from natural sources. A culture medium for stimulating growth of human and animal cells comprising: essential nutrients for cell growth, and a cell growth stimulatory amount of one or more gangliosides containing de-N-acetyl-sialic acid. A method for stimulating growth of human and animal cells cultured in vitro with a cell growth stimulatory amount of one or more gangliosides containing de-N-acetyl-sialic acid. A medicament and method for stimulating or inhibiting growth of human and animal cells by stimulating or inhibiting the production of growth stimulators selected from the group consisting of gangliosides containing de-N-acetyl-sialic acid, substances that promote synthesis of gangliosides containing de-N-acetyl-sialic acid and pharmaceutically acceptable salts thereof.
