摘要
通过建立D-半乳糖(D-galactose,D-gal)诱导的衰老小鼠模型,研究大米多肽(Rice peptide,RP)对衰老小鼠的抗氧化作用。实验测定了各组小鼠血清中过氧化氢酶(CAT)、丙二醛(MDA)、总超氧化歧化酶(SOD)指标的变化。结果表明,400mg/kg RP能显著地提高衰老小鼠血清中CAT(p<0.05)和总SOD(p<0.05)的活力,极显著降低MDA(p<0.01)的含量。RP通过抗氧化作用有效地抑制了衰老小鼠衰老症状的发展。
Antioxidant effect of rice peptide was studied through the model of aging mice induced by D- galactose. CAT,MDA and SOD in serum of aging mice were observed. Results showed 400mg/kg rice peptide could significantly improve the vitali of CAT(p〈0.05) and SOD(p〈0.05) in the aging mice serum,reduce the content of MDA(p〈0.01). Rice peptide could suppress symptoms of aging on mice by antioxidant effects.
