早在60年代,我国兽医工作者就注意到克山病流行地区的牲畜,常患一种缺硒病——动物白肌病,并发现克山病和白肌病在临床表现和病理变化上亦有某些相似之处。这就启示人们设想:人的克山病是否也因缺硒所致呢?艰苦细致的实验研究从两条途径同时着手进行了。一是要确定硒是否能有效地预防克山 As early as the 1960s, veterinarians in China noticed the livestock in the endemic areas of Keshan disease, often suffering from a selenium deficiency disease - animal myopathy and found that both Keshan disease and white muscle myopathy were also associated with clinical manifestations and pathological changes Some similarities This suggests that people imagine: Keshan disease is also due to lack of selenium? Hard and meticulous experimental study from two ways at the same time proceed. First, to determine whether selenium can effectively prevent Keshan
