为尽早控制和消灭地方性甲状腺肿(简称地甲病),从1974年我区在学习兄弟省区有孔碘管改水预防地甲病的基础上,采用无孔聚乙烯塑料碘管改水预防地甲病,现将四年(1974～1978年)来在局部地区的观察结果报告如下。一、碘管的制作及使用取长5厘米、内径1厘米、壁厚1毫米的聚乙烯塑料管,内装3～5克碘片,两端热合密闭。每户一只投入水缸中。 In order to control and eradicate endemic goiter as soon as possible (referred to as acantholyosis), from 1974, our district in the study of fraternal provinces with hole iodine to prevent water on the basis of prevention and treatment of disease, the use of non-porous polyethylene plastic tube to change water To prevent toxoplasmosis, now four years (1974 ~ 1978) to observe the results in some areas are as follows. First, the production and use of iodine tube Take a 5 cm long, 1 cm in diameter, wall thickness of 1 mm polyethylene plastic tube, containing 3 to 5 grams of iodine, heat sealed at both ends.
