摘要
以西藏灵菇发酵奶为研究对象,鲜牛奶和普通酸奶为对照,通过测定小鼠血清中的谷胱甘肽过氧化物酶、超氧化物歧化酶,血清总胆固醇、总甘油三酯、高密度脂蛋白胆固醇和果蝇繁殖时的交配潜伏期和交配持续期等指标,探索其抗衰老作用。结果表明:西藏灵菇发酵奶可以提升小鼠血清中谷胱甘肽过氧化物酶和超氧化物歧化酶活性,且都与浓度呈正量效关系;能降低血清总胆固醇和总甘油三酯,提高高密度脂蛋白胆固醇的浓度;使果蝇生殖力能力提高,交配潜伏期缩短,交配持续期延长,且均表现有量效关系。所有数据均证明西藏灵菇发酵奶确实具有一定的抗衰老能力。
This study with Tibetan kefir yoghourt for research object, fresh milk and yoghourt as contrasts, to mensurate glutathione peroxidase （GSH-PX）, superoxide dimutase （SOD）, total cholesterol （TC） ,triglyceride （TG） ,high-density lipoprotein cholesterol （HDL-C）in serum of mice, amphimixis delitescence and amphimixis duration of fruit fly （Drosophila melanogaster）, to explore anti-aging effect of Tibetan kefir yo- ghourt. The results show that Tibetan kefir yoghourt promote GSH-PX, SOD and HDL-C, and repress TC and TG. Tibetan kefir yoghourt can shorter amphimixis delitescenc and longer amphimixis duration of fruit fly. And there were dose-effect relation of Tibetan kefir yoghourt. All results attest that there is anti-aging effect by Tibetan kefir yoghourt indeed.
