硒是一种微量元素,它是谷胱甘肽过氧化酶的主要成分,有抗氧化保护细胞膜的作用。硒参加辅酶A与辅酶Q的合成,促进α—酮酸脱氢酶的活性。硒还能刺激抗体免疫球蛋白的产生,增加机体对疾病的免疫力。机体长期缺硒易造成心肌损害和骨发育异常。临床上常见一些心血管疾病患者,血清硒常常低于正常人。近年来研究发现,硒与人体肿瘤的发生有密切关系。据报道,低硒地区肿瘤的发病率及死亡率较高.肿瘤
Selenium is a trace element, which is the main component of glutathione peroxidase, antioxidant protection of cell membranes. Selenium participates in the synthesis of coenzyme A and coenzyme Q, and promotes the activity of α-keto acid dehydrogenase. Selenium can also stimulate the production of antibody immunoglobulin, increase the body’s immunity to the disease. Long-term lack of selenium can cause myocardial damage and bone dysplasia. Common clinical patients with some cardiovascular disease, serum selenium is often lower than normal. In recent years, studies have found that selenium and the occurrence of human tumors are closely related. It is reported that the incidence and mortality of tumors in low selenium areas are higher
