微量元素硒与健康的研究进展

Current Research of Microelement Se on Human Health

硒是人体必需的微量矿物质,对健康有着极其重要的作用。硒是含硒蛋白的一个组份,有维持酶蛋白催化功能的作用。近年来,以下危险因素与人体缺硒有关,诸如心血管疾病、糖尿病、肝病、克山病、大骨节病、白内障、甲状腺功能异常、生殖异常、病毒感染、癌症、不良情绪及有毒元素损害免疫功能等。食入高剂量硒会有导致儿童生长迟缓的危险,此可能是硒中毒的最好指标,因而对成年人,特别是儿童必须严格谨慎补硒。

The essential trace mineral, selenium, is of great importance on human health. As a constituent of selenoprotein, selenium help maintain the catalytic function of this protein. In recent years, selenium deficiency has been found to be a risk factor for the cardiovascular diseases, diabetes, liver disease, keshan disease, deforming arthritis, cataract, thyroid disfunction, reproduction abnormality, viral infection, cancer, bad mood and immunity damage due to toxic agents. High selenium intake can cause the children stunting, which maybe a sensitive indicator of seleniam intoxication. Therefore, supplement of selenium should be careful for the adult, especially children.
