碘是人体必需的微量元素,缺碘会造成碘缺乏症。在稳定的条件下,人体排出的碘等于摄入的碘。而尿碘约占摄入碘的80％～85％,而且尿碘取样容易,在碘缺乏病防治工作中,是不可缺少的重要指标,因此我们对全市520名小学生进行了尿碘的测定,并对聊城市碘缺乏状况进行了分析。1 对象与方法1.1 对象 聊城市8个县(市、区)共抽取520名小学生,年龄8～10岁。1.2 采尿 个体尿样是晨尿,尿样均为各县(区)送样,置于4℃冰箱保存,待用。1.3 处理与测定 按《尿碘的砷铈催化分光光度测定方法》测
Iodine is an essential trace element of the body, iodine deficiency can cause iodine deficiency disorders. Under steady conditions, the body discharges iodine equal to the amount of iodine intake. Urine iodine intake accounts for about 80% to 85% of iodine, and urine iodine sampling is easy, in the prevention and treatment of iodine deficiency disorders is an important indicator of indiscriminate, so we measured the city’s primary and secondary school students of urine iodine, The status of iodine deficiency in Liaocheng City was also analyzed. 1 objects and methods 1.1 objects Liaocheng 8 counties (cities, districts) a total of 520 primary school students, aged 8 to 10 years. 1.2 Personal urine samples urine morning urine, urine samples are sent to the counties (districts), placed in 4 ℃ refrigerator, stand-by. 1.3 Treatment and determination Press “urinary iodine arsenic cerium catalytic spectrophotometry” measurement
