The Effect of Deoxyribonucleic Acid on the Activity of Superoxide Dismutase and Peroxidase
Author(s):

Keyword:  超氧化物岐化酶过氧化物酶自由基活性脱氧核糖核酸;
Abstract: 超氧化物岐化酶(SOD)和过氧化物酶(POD)是机体内重要的抗氧化酶系之一,其作用在于清除体内的自由基,防止自由基对细胞结构的损伤.它们的活性随增龄而下降,因此自由基不断损伤细胞结构,累积最终导致细胞衰亡和动物机体衰老.老龄小鼠服用DNA一段时间后,其体内SOD和POD的活性均显著提高,因而其衰老速度可能得到一定程度的延缓.
