关于云芝多糖的抗肿瘤作用,国内虽对白山云芝作了不少工作,但云芝制剂的抑瘤率明显低于国外,且形态学观察材料甚少,至于陕西云芝则末见报道。为此,我室对二种云芝提取物的抗肿瘤作用进行了实验观察。于立坚等的工作指出:陕西云芝和白山云芝提取物对小鼠皮下移植的肉瘤180有明显的抑瘤作用,其抑瘤率分别为69.7%和55.5%,并提出了作用时相问题[陕西新医药9(2):46,1980]。本文报 Regarding the anti-tumor effect of Yunzhi polysaccharide, although China has done a lot of work on Baishan Yunzhi, the inhibitory rate of Yunzhi preparations is obviously lower than that of foreign countries, and there are few morphological observation materials. As far as Shaanxi Yunzhi is reported at the end of the report, . To this end, our laboratory conducted an experimental observation of the anti-tumor effects of two kinds of Yunzhi extracts. Yu Lijian et al. pointed out that the extracts of Yunzhi and Baishan Yunzhi have significant inhibitory effects on the subcutaneously transplanted sarcoma 180 in mice, and the tumor inhibition rates are 69.7% and 55.5%, respectively, and the action phase is proposed.
