摘要: 用邻苯三酚在碱性条件下自氧化产生的超氧阴离子自由基(O2·-)对红细胞膜的过氧化损伤作用为研究模型,探讨银耳多糖对红细胞膜的保护作用。结果表明,银耳多糖对红细胞膜有抗氧化作用,表现为膜蛋白交联作用减少;膜流动性趋于正常,红细胞溶血率降低。通过邻苯三酚在碱性条件下自氧化的试验,提示银耳多糖对邻苯三酚自氯化反应没有抑制作用。

Abstract: The present paper discusses the role of tremella fucitormis Polysaccharide(TFS) in pro-tection of erythrocyte membranes from damage by superoxide anion O2·- generated from auto-oxidation of pyrogallie acid(pA) at pH 8.4. The addition of TFS to pyrogallic acid and ery-thocyte membranes system caussed a decrease in high molecular weight protein polymers (HMP), an increase in fluidity and a depression in hemolysis rate of the red cells, Showing TFS has antiperoxidation effect on erythrocyte membranes. However no inhibition of TFS on auto-oxidative reaction of PA was shown when the auto-oxidation experiment was under taken under basic condition.

Key words: tremella fuciformis polysaccharide, erythrocyte membrane, superoxide anion, lipoperoxide
