本实验测试了1、3、6、9、12和18月龄雄性小白鼠红细胞内硒-谷胱甘肽过氧化物酶(SeGSH-Px)活性。结果表明,1至6月龄动物随年龄增加酶活性增加(P<0.01),6月龄后随着动物年龄增加,酶活性下降(P<0.01);给满6月龄小白鼠饲喂某些天然保健食物75天后,酶活性与对照组相比上升显著(P<0.01),认为可把该酶视为动物衰老的生化指标之一。 This experiment tested selenium-glutathione peroxidase (SeGSH-Px) activity in red blood cells of 1, 3, 6, 9, 12 and 18 months old male mice. The results showed that the enzyme activity increased with age in the animals from 1 to 6 months of age (P<0.01), and the enzyme activity decreased with the age of the animals after 6 months of age (P<0.01); feeding a 6-month-old white mouse After 75 days of natural health foods, the enzyme activity increased significantly compared with the control group (P<0.01). It is considered that the enzyme can be regarded as one of the biochemical indicators of animal aging.
