摘要
报告了盐池县马儿庄监测点的水氟、氟斑牙、氟骨症患者的症状与体征,骨 X线,包括骨密度、骨结构(骨小梁)、骨周与关节改变以及群体尿氟的变化。结果表明,8年来为群众供给充足的水氟稳定在国家标准内0.8mg/L 饮用水后,摆脱了原均值为6.63mg/L 高氟危害。400余名成人氟斑牙型度稳定未变,但改水后出生的儿童已扪出恒牙的小孩长出了洁白有光泽的牙齿,避免了氟斑牙的损害。氟骨症患者的症状和体征改善率达60～90%。骨 X 线片结果显示:部分患者骨密度明显下降,骨小梁细密、清晰。群体尿氟值降至3.07mg/L,接近宁夏非病区正常值2.6mg/L 水平。改水取得了明显的防治效果。
Reporting the fluorone concentration of drinking water,mott- led enamel,Urine fluorine concentra- tion of part of village population,as well as the clinical signs & symptoms of osteoflurosis patients together with their x-ray film bone density,bone/ smaller ridges structure,peripheral tissues of bone & arthropathy in Wa' erzhuang village of Yanchi County. Since the supply of qualified drinking water(fluorine concentration only 0.8 mg/L)in year 1982,a successive dyn- amic monitoring of endemic fluorosis has been conducted in that village spot from year 1983 up to the present—— eight years if counting to 1991.The 1980 high fluorine of drinking water (6.63mg/L)disappared,and the harm- ful endemic fluorosis manifestations it caused have early or late abated/been alleviated,or even disappeared,The mottled enamel in 400 odd adults has not become more serious,furthermore all those children born after 1982 have erupted & kept up white shiny teeth,The improvement rate of clini- cal signs & symptoms of the osteoflu- orosis patients has been 60～90%;bone Xary films in part of patients showed obviously decreased bone density and clear & fine-close smaller ridges.Ur- ine fluorine of part of village popul- ation lowered to 3.07mg/L in 1991, almost approaching the Ningxia level of fluorosis-negative areas in Ningxia ——2.6mg/L.
