对晋东南地甲病区和部分非病区的水,土、粮、发中微量碘和硒进行了分析,结果是(内环境)发中和(外环境)水、土、粮中硒含量均为重病区低于轻病区,轻病区低于非病区,且有显著性差异。在碘含量较恒定的情况下,可以看出硒、碘比值越低,地甲病病情越重。由此笔者认为缺碘是地甲病的主要原因,但是地甲病发病与硒含量缺乏也有一定的关系,所以在防治中,凡是硒元素缺乏的病区在补碘的同时也应补硒。 The trace amounts of iodine and selenium in water, soil, grain and hair in the endemic areas of A and B and the non-endemic areas in southeastern Shanxi were analyzed. The results showed that the content of selenium in water, soil and grain in (internal environment) All were less severe than wasting area, less than non-wasting area, and there were significant differences. In the case of more constant iodine content, we can see that the lower the selenium and iodine ratio, the more severe the disease is. Therefore, I believe that iodine deficiency is the main reason for A to D, but the incidence of A to G and lack of selenium content also have a certain relationship, so in the prevention and treatment, all the selenium deficiency in the ward should also complement iodine.
