我们多年的工作证明克山病地区多处于低硒地带。病区居民的血与头发以及粮食中的硒含量均较低。用亚硒酸钠预防克山病有明显的效果,表明克山病发病与缺乏硒有关。动物实验证明血和组织中的谷胱甘肽过氧化物酶(以下简写为GSH-Px)活力与摄入的硒量密切相关,测定血中的GSH-Px活力可作为评价机体中硒营养状况的一个指标。为了了
Our many years of work prove that Keshan disease is mostly in the low selenium zone. Ward residents of the blood and hair and grain selenium content is low. Sodium selenite to prevent Keshan disease have a significant effect, indicating that the incidence of Keshan disease and the lack of selenium. Animal experiments show that the blood and tissues of glutathione peroxidase (hereinafter abbreviated as GSH-Px) activity and intake of selenium is closely related to determination of blood GSH-Px vitality can be used as a measure of body selenium nutritional status An indicator. In order to
