摘要
目的 比较灰树花多糖粗品 (PGF)与纯品 (PGF-1 )的抗肿瘤作用及对荷瘤小鼠免疫功能的影响。方法 : 采用 S1 80 移植瘤模型 ,观察 PGF与 PGF-1的抗肿瘤效果 ,并进行免疫学指标测定。结果 : PGF与 PGF-1有抑制 S1 80 肿瘤生长的作用 ,并能显著增强荷瘤小鼠脾指数、巨噬细胞吞噬功能、二硝基氟苯 (DNFB)所致的迟发型超敏反应 (DTH)、淋巴细胞转化能力、脾细胞抗体生成能力和血清 Ig M溶血素的含量 ,PGF的抑瘤效果优于 PGF-1。结论
Objective:To compare the anti tumor activity and immune enhancing effect of crude(PGF) and purified (PGF 1) polysaccharide from Grifola frondosa. Methods:S 180 bearing mice were used as animal model. The effects on tumor weight and immune function were investigated. Results:PGF and PGF 1 showed inhibitory activity on S 180 growth. They could also increase weight of immune organs and improved the phagocytic function, DTH response, lymphocyte proliferation, antibody formation in splenic cells and content of serum HC IgM markedly. PGF was better than PGF 1. Conclusion:Both PGF and PGF 1 can inhibit S 180 tumor growth and enhance immune function in S 180 bearing mice.
