全国克山病病区地理考察及内环境研究,已知病区处在低硒地带,我院在1965年首次应用亚硒酸钠预防克山病以来.全国各地普遍应用,对预防急型克山病,皆取得良好效果。但为什么硒能够预防该病的急发?硒对心肌起什么作用?本文拟由生物化学的角度,用病区粮喂养的动物心肌及患者尸检心肌,研究其心肌代谢,试图阐明低硒饮食对心肌的生化损害及硒对心肌作用的原理,提供实验依据,以探讨硒在克山病发病学及 National Keshan disease wilderness geographical investigation and environmental studies, known ward in the low selenium zone, our hospital in 1965 for the first time since the prevention of Keshan disease sodium selenite has been applied across the country, to prevent acute g Mountain disease, have achieved good results. However, why selenium can prevent the rapid onset of the disease selenium on the role of the heart? This biochemical point of view, the ward with the ward of food-fed animal myocardium and myocardial necrosis of patients to study their myocardial metabolism, trying to clarify the low-selenium diet Myocardial biochemical damage and selenium on the role of myocardial theory, to provide experimental evidence to explore the pathogenesis of selenium in Keshan disease and
