Balb-c小鼠20只,随机分成实验组和对照组,实验组小鼠进行游泳训练。6周后均处死取血、肝、心以测定丙二醛(MDA)、超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GSH-Px)和过氧化氢酶(CAT)。结果显示,游泳训练并不会增加小鼠体内的MDA生成,且可显著提高小鼠体内CuZn-SOD、Mn-SOD以及肝线粒体GSH-Px等抗过氧化物酶的活力。 Twenty Balb-c mice were randomly divided into experimental group and control group, and mice in experimental group were subjected to swimming training. Six weeks later, blood, liver and heart were sacrificed to determine the content of MDA, GSH-Px and CAT. The results showed that swimming training did not increase MDA production in mice and significantly increased the activities of CuZn-SOD, Mn-SOD and GSH-Px anti-peroxidase in mice.
