人体必需微量元素对人类生理及病理意义的重要性早已为人们公认。1957年Schwarz指出,硒是抑制大鼠肝坏死的“第三因子”,至1975年由Awasthi证明,硒是人体必需微量元素,为人血红细胞谷胱甘肽过氧化酶(GSH—Px)的组成成分。
The importance of trace elements essential to human physiology and pathology has long been recognized. In 1957, Schwarz pointed out that selenium is the “third factor” that inhibits hepatic necrosis in rats. It was demonstrated by Awasthi in 1975 that selenium is an essential trace element of the human body and is a component of human erythrocyte glutathione peroxidase (GSH-Px) ingredient.
