摘要:

采用ESR自旋捕捉方法研究肉苁蓉苷类化合物对体外产生的·OH等活性氧自由基的清除能力; 低温(液氮)ESR技术、免疫学实验技术和生化方法检测大鼠肾组织内活性氧自由基水平及血清SOD水平和GSH-Px酶活性。结果提示肉苁蓉苷类化合物能强烈抑制体外·OH等活性氧自由基,同时对于糖尿病肾病引起的自由基损伤具有预防和修复作用; 小鼠碳粒廓清法研究结果表明肉苁蓉苷类化合物能明显增加小鼠血中吞噬能力及免疫器官的重量。

Abstract: Cistanoside compounds were studied as the scavengers of hydroxyl and superoxide anion free radicals with spin trapping ESR method in vitro. Low-temperature ESR technique, experimental technique of immunotoxicology and biochemical method were used to detect the level of reactive oxygen radicals in kidney tissue of rats and SOD level and GSH-Px activity in rat serum. The results indicated that cistanoside compounds could inhibit reactive oxygen free radicals in vitro and prevent and repair the free radical damages for diabetic nephropathy. The experimental data of “arbon-particle detection in mouse serum” showed that cistanoside compounds could improve the phagocytotis index of macrophages (Mj) in mice blood and increase the weights of immune organs of mice.

Key words: Cistanoside, Reactive oxygen radicals, Antioxidation, ESR, Immunity
