硒作为生命必需微量元素是在1957年被发现的。近30年来的大量研究证明,硒在维持生物功能、预防和治疗疾病方面均有重要作用。近年来有关硒的研究又有了新的进展。尤其是自报道硒是一种必需的微量营养素及可能是一种天然的癌症抑制素以来,硒已引起人们广泛的兴趣和极大的关注。一、硒的生物功能硒是机体必需微量元素之一。是机体自身稳定作用的中枢,是生物学中许多问题的关键元素。其生理功能除抗氧化、保护细胞膜、在红细
Selenium as an essential trace element of life was discovered in 1957. In the past 30 years, a large number of studies have shown that selenium plays an important role in maintaining biological functions and preventing and treating diseases. In recent years, research on selenium has made new progress. In particular, selenium has attracted a great deal of interest and great attention since the selenium is reported to be an essential micronutrient and possibly a natural cancer suppressor. First, the biological function of selenium is one of the necessary trace elements of the body. Is the backbone of the body’s own stabilizing function and is a key element of many problems in biology. In addition to its physiological function of anti-oxidation, protect the cell membrane, in the red fine
