乳蛋白活性肽的延缓衰老作用研究

Study on Effect of Bioactive Peptides on Delaying Aging

目的 研究乳蛋白活性肽对果蝇寿命和大鼠氧化与抗氧化指标的影响。方法 果蝇生存实验 ,大鼠抗氧化实验。结果 乳蛋白活性肽可明显延长两个性别果蝇的最高寿命和平均寿命 ;同时可明显降低大鼠血清中丙二醛(MDA)含量 ,并显著升高大鼠抗氧化酶 (超氧化物歧化酶SOD及谷胱甘肽过氧化物酶 (GSH PX)的活力。结论 乳蛋白活性肽有延缓衰老作用。

Objective To study on the effect of bioactive peptides from milk protein on the lifespan of drosophila melanogaster and the oxidative and antioxidative indice of rats.Methods Survivable test of drosophila melanogaster and antioxdative test of rats.Results The bioactive peptides prolonged significantly the the time of half death of Drosophila melanogaster,and increased significantly the longest and average lifespan of both the male and female.Furthermore,the bioactive peptides decreaed the content of MDA,and increased the activity of SOD and GSH P X significantly.Conclusion The bioactive peptides from milk could have the action to delay the process of the aging.
