1976年克山病高发年易患人群发硒0.126mg/kg,1989年低发年发硒0.167mg/kg,1991年和1993年基本控制年发硒分别为0.179mg/kg 和0.284mg/kg。应用微机进行多元逐步回归分析显示:发硒与克山病发病率、潜克检出率、心电图异常和心胸比例异常检出率呈负相关。
Keshan disease in 1976, the susceptible population issued selenium 0.126mg / kg, seventy-one seventy-eight seventy-seven selenium 0.167mg / kg in 1991, seventy years of basic control of selenium in 1991 and 1993 were 0.179mg / kg and 0.284mg / kg . The multiple stepwise regression analysis using computer showed that there was a negative correlation between selenium and Keshan disease, the detection rate of latent gram, the abnormality of electrocardiogram and the abnormal rate of cardiothoracic proportion.
