自60年代以来,科学工作者们逐渐发现了多糖具有复杂而又多方面的生物活性。在初步研究中,人们的注意力基本集中在抗肿瘤和抗放射两个方面。过去对于癌症的治疗主要有三个方面:即手术、放疗和化疗。而目前免疫疗法也已成为治疗肿瘤的手段之一,它是以提高机体免疫力来达到抗放和抗肿瘤作用的。在这方面,多糖体正初露锋芒,所以引起了广大科学工作者的兴趣,并做了些具体的工作。如从担子菌分离得到的PS—K多糖以及香菇多糖对小鼠S—180瘤株均有明显的抑制作用,并已作为
Since the 1960s, scientists have gradually discovered that polysaccharides have complex and diverse biological activities. In the preliminary study, people’s attention basically focused on the two aspects of anti-tumor and radiation resistance. In the past, there were three main treatments for cancer: surgery, radiotherapy, and chemotherapy. At present, immunotherapy has become one of the means to treat tumors. It is to improve the immunity of the body to achieve anti-resistance and anti-tumor effects. In this regard, polysaccharides are beginning to show their appearance, which has aroused the interest of scientists and made specific work. For example, PS-K polysaccharides and lentinan isolated from basidiomycetes have obvious inhibitory effects on mouse S-180 tumor strains and have been used as
