硒及维生素E对力竭游泳后小鼠肺组织自由基代谢的影响

Effect of Selenium and Vitamin E on Free Radical Metabolism of Rat Lung after Exhaustive Swimming

为了研究硒和维生素E对小鼠大运动量后机体肺组织丙二醛(MDA)含量和谷胱甘肽氧化酶(GSH-PX)活性的影响,本实验通过对小鼠进行不同负荷的游泳训练,并给大运动量训练后的小鼠补充硒和维生素E,结果发现:力竭游泳后即刻,MDA、GSH-PX活性有明显变化。Se和VE在抗MDA、GSH-PX方面有明显的协调作用,可抑制MDA含量和GSH-PX活性变化。

The purpose of the research was to explore the effect of Selenium (Se) And Vitamin (VE) on the lung structure of MDA any GSH-PX in rat immediately after Exhaustive swimming were observed. After 6 week抯 swimming training, the plasma Concentrations were tested by rat. There were significant difference in MDA Activity, GSH-PX content and light micrographs of lung tissue showed apparent evidences of Congestion, supplement ting of Selenium and Vitamin E may attenuate such Changes.
