在克山病的生物地球化学病因研究中,我们多年来对镁进行了大量的工作,虽然从动物模型复制、镁预防等方面发现低镁是克山病病因中,一个值得重视的因素,但就全国来看,病区某些粮菜品种的含镁量并不低于非病区,而且,个别病区水中的含镁量偏高,特别是近年来某些微量元素与心血管疾病发病的关系,已有不少报导。因此,有必要在继续研究镁的同时,探讨微量、常量元素与克山病的关系。本文以克山病区和非病区粮菜长期饲养犬,对比观察心肌、膈肌,全血及毛中的 We have done a lot of work on magnesium for many years in the biogeochemical etiology of Keshan disease. Although low magnesium is a factor worthy of attention in the etiology of Keshan disease, from animal model replication and magnesium prevention, As far as the whole country is concerned, the magnesium content of some grain varieties in the ward is not lower than that in non-ward areas. In addition, the magnesium content in water in individual ward areas is high, especially in recent years some trace elements and cardiovascular diseases There have been many reports. Therefore, it is necessary to study the relationship between micro and macroelements and Keshan disease while continuing to study magnesium. In this paper, Keshan ward and non-ward food long-term breeding dogs, compared to observe myocardial, diaphragm, whole blood and hair
