新疆奎屯-乌苏山前倾斜平原地方性甲状腺疾病的地理分布
The Geographic Distribution of Endemic Goiter on the Inclined Plain before Tianshan Mountians in Kuitun-Usum,Xinjiang
【摘要】 <正> 奎屯-乌苏山前倾斜平原为一典型的离子淋溶-累积体系。自天山隆起后,地势高处的水溶性碘借助于流经水的作用,不断地被淋溶并被搬迁至地势低洼处,形成平原上部碘低,平原下部碘高的重新分配现象。在受地表条件影响较少的深层地下水中这种分布更明显。地方性甲状腺疾病分布规律与此情况吻合,即平原上部为缺碘区,有地方性甲状腺肿流行并
【Abstract】 This paper describes the distribution of the water iodide on the inclinedplain before Tianshan Mountains, in Kuitun-Usun, and the relation between iodidein drinking water and endemic goiter.In the mountainous area and the upper areaof the inclined plain, where the water iodide is lower, we observed 55 and 58.9% incidences of enlargement of the thyroid among the preadolescent schoolchildren, and incidences of goiter among the population are 11.7 and 23.2% respecti-vely.In the low area of the plain, the goiter disappears due to insufficient iodi-de, but iodide-induced goiter appears.Regression analysis of the incidence amongpreadolescent schoolchildren and the water iodide have shown that while wateriodide is lower than 45μg/L, the higher the water iodide, the lower the incidenceis; when the water iodide is 30—60μg / L, the incidence is lowest; however,when iodide is more than 60μg/L, the incidence will be raising as the wateriodide increases.
