地方性甲状腺肿是分布较广、患病人数较多的地方病。其致病因素主要是缺碘。本病重症患者劳动力显著下降;流行较严重的地区可有痴呆、聋哑、矮小为特征的地方性克汀病(呆小病),直接影响劳动人民的身体健康。从1964年开始,我们遵照毛主席关于“预防为主”的方针,先后在几个县,对地方性甲状腺肿采用了碘盐进行了防治,取得了一定成绩。现介绍如下:碘盐加工供应方法和简易测定法一、碘盐加工方法:一般分为干法和湿法两种:干法加碘:用钢磨将100公斤粗盐磨成盐面,将 Endemic goiter is a widely distributed, more endemic diseases endemic. The main risk factors are iodine deficiency. The labor force of critically ill patients significantly decreased; more endemic areas may have dementia, deaf and dumb, characterized by endemic cretinism (small lesions), a direct impact on the health of working people. Since 1964, following the principle of “prevention first” adopted by Chairman Mao, we have made some achievements in the prevention and control of endemic goitre using iodized salt in several counties. Now introduced as follows: Iodized salt processing supply method and a simple determination method, Iodized salt processing methods: Generally divided into two kinds of dry and wet: dry iodine: 100 kg of coarse grinding salt into salt with a steel mill,
