碘盐防治甲状腺肿的效果很好,我省已经推广了多年。碘盐防治甲状腺肿的浓度,目前国内外尚无统一认识。原则上应根据病区的缺碘程度,居民每天的吃盐量,食盐本身的含碘量,碘盐中碘化物的稳定性和保管储存情况等而定。据陕西省眉县1975年观察,食用1/2万、1/3万、1/5万碘盐9个月后,有效率均在85～87%之间,防治效果无明显差别。碘化物在阳光下易分解而析出碘,在酸性或氧化剂环境中也易析出碘.因此,加工好的碘盐应放在阴凉、干燥的仓库和密闭的容器中,或者在碘盐中加入一定的硷性药物,以减少碘的析出。为了保证碘盐的稳定性,也可用碘酸钾代替碘化钾,或在碘盐中加入千分之一的碳酸钠、硫代硫酸钠、氢氧
Iodized salt prevention and treatment of goiter well, our province has been promoted for many years. Iodized salt prevention and treatment of goiter concentration, at home and abroad there is no uniform understanding. In principle, it should be based on the level of iodine deficiency in the ward, the daily salt intake of residents, the iodine content of salt itself, the stability of iodide in iodized salt and the storage and storage of iodine. According to the observation of Meixian County in Shaanxi Province in 1975, the effective rate was between 85% and 87% after consuming 1 / 10,000, 1 / 30,000 and 1 / 50,000 iodized salt for 9 months. There was no significant difference in the control effect. Iodide is easily decomposed in the sun and the precipitation of iodine, acid or oxidant environment is also easy to precipitate iodine.Therefore, the processed iodized salt should be placed in a cool, dry warehouse and airtight containers, or add a certain iodine salt Alkaline drugs to reduce the precipitation of iodine. In order to ensure the stability of iodized salt, potassium iodate can also be used instead of potassium iodide, or one-thousandth of an iodine salt of sodium carbonate, sodium thiosulfate,
