通过给小猪口服~(75)Se标记的亚硒酸钠了解硒掺入谷胱甘肽过氧化物酶(GSH-Px)的进程和探讨机体内是否存在其它含硒的物质。 二只体重为20公斤的十周龄Yorkshire小猪。第一只小猪一次口服100微居里~(75)Se,每一定间隔取2毫升颈静脉血样,测其~(75)Se放射性强度及进行SephadexG-150凝胶过滤。结果表明全血~(75)Se在第8小时
The process of GSH-Px incorporation into selenium in piglets was investigated by oral administration of ~ (75) Se-labeled sodium selenite to explore the existence of other selenium-containing substances in the body. Two ten-week-old Yorkshire pigs weighing 20 kg. The first pig was orally administered with 100 μCi-75 Se, and two milliliters of jugular vein blood was taken at regular intervals. The radioactivity of ~ (75) Se was measured and Sephadex G-150 gel filtration was performed. The results showed that whole blood ~ (75) Se was at 8 hours
