应用亚硒酸钠预防克山病急性发病有明显效果,克山病病区内外环境中硒状态处于低硒水平,说明硒是与克山病有密切联系的一个元素。进一步研究硒在机体内的代谢,对于探讨硒防原理、克山病病因学和发病学均具有重要意义。已知我省克山病病区内普遍存在着动物(如仔猪、羔羊等)的缺硒病,为研究硒的代谢提供了良好模型。 Application of sodium selenite in prevention of acute Keshan disease has a significant effect, Keshan disease in selenium environment inside and outside the state of low selenium levels, indicating that selenium is closely linked with Keshan disease is an element. Further study of the metabolism of selenium in the body, for the study of selenium prevention principle, Keshan disease etiology and pathogenesis are of great significance. It is known that the selenium deficiency disease of animals (such as piglets, lambs, etc.) is common in the Keshan disease area in our province and provides a good model for studying selenium metabolism.
