黑木耳、银耳和银耳孢子多糖生物活性的比较

本文比较了黑木耳多糖、银耳多糖及银耳孢子多糖在吞噬细胞功能、抗放射和升高白细胞三方面的生物活性。结果表明:三种多糖均有明显增强吞噬细胞吞噬功能的作用,其吞噬指数分别为对照组的2.17、3.17和2.60倍,吞噬百分数分别为对照组的1.38、1.57和1.45倍。黑木耳、银耳孢子多糖还有较好的抗放射作用,60Coγ射线照射后(总剂量800伦琴)观察20天,存活率分别为对照组的1.56和1.78倍。此外,三种多糖均能升高由环磷酰胺引起的白细胞降低。胞平均下小白鼠在注射环磷酰胺后两天,对照组、黑木耳组、银耳组及银耳孢子多糖组白细降率分别为64.8％、39.2％、20.3％和10.9％。

COMPARISON OF BIOLOGICAL ACTIVITIES OF THREE POLYSACCHACHARIDES

Three polysaccharides from Auricularia auricala, Tremella fuciformis Berk and the spores of Tremella fuciformis Berk were found to enhance the phagocy- tosis of microphage. The phagocytic indexes increased respectively by 2.12, 3.17 and 2.60 times as compared with the controlled group. The polysaccharides of Auricularia auricula and spores of Tremella fuciformis Berkhad a marked an- tiradical effect. The survival rates were 1.56 and 1.78 times of that of the con- trolled group grespectively. Thepolysaccharides of Auricularia auricula,Tremella fuciformis Berk and spores of Tremella fuciformis Berk showed remarkable antagonist action to leukopenia caused by cyclophosphamide. Two days after clcyophospha- mide was administrated intraperitonoeslly, the occurence rate of leukopenia for three testing groups were 39.2%,20.03%10.9%,respectively,while the controlled group showed a rate of 60.8%.
