【摘要】通过非脂质体系抗氧化实验、体外抗氧化实验研究了葛仙米藻蓝蛋白的抗氧化能力。结果表明:葛仙米藻蓝蛋白对清除O2·、·OH自由基和H2O2具有较好的量效关系。在体外反应体系中,葛仙米藻蓝蛋白能显著地降低MDA生成和血和肝中过氧化物的含量,起到保护细胞膜和红血球的作用。显示葛仙米藻蓝蛋白对小鼠肝线粒体损伤具有保护作用,并能显著影响血浆的抗活性氧能力。更多还原

【Abstract】 In this experiment, ability of anti-oxidation of phycocyanin in Nostoc sphaeroids Kutz by anti-oxidation experiment with non-lipid system and anti-oxidation in vitro was studied. The results indicated that relationship between concentration and scavenging effect of phycocyanin on superoxide free radical (O·2), hydroxyl free radical (·OH) and peroxide hydrogen (H2O2) was evident. Contents of MDA and peroxide in blood and liver of mice were reduced in vitro, so phycocyanin could cell protect membrane and erythrocyte. Obviously, phycocyanin in Nostoc sphaeroids Kutz could protect rat liver plastomasme from being damnified and effected evidently on ability of anti-oxygen of blood plasma.更多还原
