在克山病的病因研究中,曾提出克山病可能与机体内钼缺乏有关,同时提出机体的缺钼状况还会由于来自病区过量的铜而加重。通过实验研究,已证明在病区粮食中加入钼酸铵能减轻心肌损伤。还有根据食管癌高发地区人发中钼的含量偏低,认为人机体的相对低钼或缺钼状态,在食管癌的发生上可能具有意义。钼和铜都是生命必需的微量 In the etiology of Keshan disease, Keshan disease was suggested that Keshan disease may be related to the lack of molybdenum in the body, and at the same time, the lack of molybdenum in the body is also exacerbated by excessive copper from the ward. Through experimental studies, it has been shown that adding ammonium molybdate in the ward food can reduce myocardial damage. There is also a high incidence of esophageal cancer in areas of human hair molybdenum content is low, that the human body relatively low molybdenum or molybdenum status, the occurrence of esophageal cancer may have meaning. Both molybdenum and copper are minor traces of life
