越来越多的材料证明硒是一种必需的微量元素。硒对机体的重要作用,不但从白肌病、渗出性素质、食饵性肝坏死或樱桃心等硒缺乏动物病的研究得以证明:而且从硒对蛋白质营养不良儿童的治疗作用、硒及维生素E与婴儿猝死的关系、硒与龋齿发生的关系等工作也显示出硒对人体的重要作用。近年来对硒的生理生化作用的研究,特别是对动物体内含硒的谷胱甘肽过氧化物酶(Glutathione Peroxidase)的研究,更进一步表明硒参与着保持机体正常功能的重要代谢过程。至于硒对有机汞等毒物的保护作用,硒对某些化学致癌物质的拮抗作用,以及人类环境中硒污染可能引起的影响等等都正日益受到重视。 More and more materials prove that selenium is an essential trace element. The important role of selenium on the body, not only from white muscle disease, exudative quality, hepatic necrosis or cherry heart, such as selenium-deficient animal disease studies have proved: and from the treatment of children with protein malnutrition, selenium and vitamin E The relationship with sudden infant death and the relationship between selenium and dental caries also showed that selenium has an important effect on the human body. In recent years, researches on the physiological and biochemical effects of selenium, especially on the selenium-containing glutathione peroxidase in animals, further prove that selenium participates in important metabolic processes that maintain the normal function of the body. As selenium on the toxic effects of organic mercury, such as the protective effect of selenium on certain chemical carcinogens antagonistic effects, as well as the human environment may be the impact of selenium pollution and so on are more and more attention.
