在我国乃至世界范围内,饮水氟含量过高是导致氟中毒的重要原因之一。多年来,在饮水型病区已广泛采用了打深井改换水源的方法来预防氟中毒。采取这一措施后地氟病病区变化及病人的转归情况如何是目前防治工作中急需了解的问题。为此,笔者对一改水5年的重病屯进行了系统的临床及流行病学研究,现将结果报告于后。1 材料和方法 调查地点在吉林省大安市查干乡先锋村刘家围子屯。该屯内原有小口浅井56眼,水氟含量为0.8
In our country and even in the world, the high fluoride content in drinking water is one of the important causes of fluorosis. Over the years, drinking-water wards have been widely used to replace deep-well water sources to prevent fluorosis. After taking this measure, the changes of endemic fluorosis and the outcome of patients are the problems urgently needed to understand in the current prevention and treatment work. To this end, the author of a 5-year water disease in Tuen conducted a systematic clinical and epidemiological studies, the results reported later. 1 materials and methods survey site in Da’an City, Jilin Province Chagan Township, Pioneer Village, Liu Wai Wai Tsuen. The original wells in the small wells 56 wells, the fluorine content of 0.8
