硒是一种必需的微量元素,它是谷胱甘肽过氧化物酶的一部分,营养性硒缺乏引起的地方性心脏病,在中国称为“克山病”,大量临床研究证明饮食中补充亚硒酸钠可显著降低克山病发生率。在工业化的西方,营养性硒缺乏被认为与心血管疾病相关。作者发现,冠心病病人的血清硒及全血硒值均比健康对照为低。而且,血清硒与心组织硒呈正相关。此外,作者还观察了血与组织中的锌、铜、铁、镁和钾等微量元素的相关性。本文报告作者测 Selenium is an essential trace element, which is part of glutathione peroxidase, a localized heart disease caused by a lack of nutritive selenium, called “Keshan disease” in China. A large number of clinical studies have shown that supplementation in the diet Sodium selenite can significantly reduce the incidence of Keshan disease. Nutritional selenium deficiency is thought to be associated with cardiovascular disease in the industrialized West. The authors found that selenium and selenium levels in patients with coronary heart disease were lower than those in healthy controls. Moreover, serum selenium and heart tissue selenium was positively correlated. In addition, the authors also looked at the association of blood with trace elements such as zinc, copper, iron, magnesium and potassium in tissues. This article reports the authors test
