硒(Selenium,Se)作为一个微量元素,自1817年被发现后的相当长时期内,在医学上未被引起注意。人们一直不知道硒有什么生理功用,也不知道硒是否为人体所必需。自从发现了第三因子与硒的关系,以及用硒可以有效地防治家畜白肌病,硒在医学上才逐渐被重视起来。近年来,越来越多的研究结果表明,硒很可能象铜、锌、锰、钼……等一样,是一种为动物和人体所必需的微量元素。
Selenium (Se), as a trace element, has been medically unrecognized for quite a long time since its discovery in 1817. People do not know what physiological function of selenium, do not know whether selenium is necessary for the human body. Since the discovery of the third factor and the relationship between selenium and selenium can effectively control domestic white matter myopathy, selenium in medicine has gradually been taken seriously. In recent years, more and more studies have shown that selenium is likely to be trace elements such as copper, zinc, manganese, molybdenum, etc., which are necessary for animals and humans.
