地方性氟中毒是我区最为常见的疾病,目前在调查诊断该病上,除氟斑牙简便易掌握外,由于X光照片成本贵,且多数农村无电,所以采用测定尿中氟浓度来诊断地方性氟中毒较为方便。但至今我国还没有尿氟诊断标准。我站于1982年4月对毕节县健康人群200人进行尿氟侧定,调查对象系未发现有氟斑牙者,尿液系晨一次尿,测定方法为氟电极法。测定结果,尿氟范围在0.032～6.000毫克/升,均值为1.667毫克/升,标准差1.058,标准误0.075,测定结果呈正态分布。据统计,尿氟<3毫克/升者有182人,占91％,因此,我们认为尿氟正常值以小于3毫克/升为宜。根据贵阳市防疫站在贵阳郊区对氟病发病点和对照
Endemic fluorosis is the most common disease in our region, the current diagnosis of the disease in the survey, in addition to dental fluorosis easy to grasp, because the X-ray expensive, and most rural areas without electricity, so the determination of urinary fluoride concentration Diagnosis of endemic fluorosis more convenient. But so far our urine fluoride diagnostic criteria. I was standing in April 1982 Bijixian healthy population of 200 people side urine fluoride test subjects were found no dental fluorosis, urine morning urine, the determination of fluoride electrode method. The results showed that urine fluoride ranged from 0.032 to 6.000 mg / l, with an average of 1.667 mg / l, a standard deviation of 1.058 and a standard error of 0.075. The measurement results showed a normal distribution. According to statistics, there are 182 people with urinary fluoride <3 mg / L, accounting for 91%. Therefore, we think normal urinary fluoride should be less than 3 mg / L. According to Guiyang City Epidemic Prevention Station in Guiyang suburb of fluorine incidence and control points
