生物组织成份中,糖是最早为人们认识的一种.如食糖、麦芽糖、纤维素、淀粉都是我们熟知的.人们普遍认为糖的主要功能是为生物提供能量和参与一些生物结构.而做为药用,长期以来仅有屈指可数的几种.七十年代以来,随着免疫学和生物膜研究的新进展,以及越来越多复合多糖的发现,一些多糖类做为免疫型抗癌药受到了广泛重视,某些多糖的降血糖、降血脂、抗凝血、抗溃疡等作用也相继发现.原有一些多糖类药物的种类和应用也得到了发展.下面简述多糖类的药物作用并各举具体例子说明之. 调节免疫功能,提高抗肿瘤、抗病毒能力多糖类在肿瘤免疫治疗中显示促胸腺体液反应,具“宿主中介作用”刺激网状内皮系统,提高宿主对癌细胞的特异抗原免疫反应力;多糖是细胞膜组分,故可强化正常细胞抵御致癌物侵袭,提高机体抗病能力.现举几例说明.
Sugar is one of the earliest known biological components of biological tissue, such as sugar, maltose, cellulose, starch are well known to us.It is generally believed that the main function of sugar is to provide energy for organisms and participate in a number of biological structures. For medicinal purposes, there are only a handful of long-term since the seventies, with the new progress of immunology and biofilm research, and more and more polysaccharide discovery, some polysaccharides as immune Anti-cancer drugs have received widespread attention, some of the hypoglycemic polysaccharide, hypolipidemic, anticoagulant, anti-ulcer and other effects have also been found in the original type and application of some polysaccharides have also been developed. The role of drugs and each of the specific examples of sugar.Adjustment of immune function, improve anti-tumor, anti-virus ability polysaccharide in tumor immunotherapy showed thrombolytic response, with “host mediator effect” to stimulate the reticuloendothelial system, Improve host immune response to cancer-specific antigenic reaction; polysaccharide is a cell membrane component, it can strengthen the normal cells against cancer invasion, improve the body resistance to disease.
