本文报告161例早期地方性氟骨症,并以125例健康组作对照。着重分析其骨骼的X线表现。患者皆为11～14岁的学龄儿童,饮水含氟量为4.1～23毫克/升,对照组为0.11～1.05毫克/升。生化检查除血钙对照组近似外,血氟、尿氟、血磷及碱性磷酸酶均较对照高,其中尿氟高于对照组12.5倍。患者均无自觉症状,但均有不同程度的氟斑牙,该流行区的家畜亦有严重的氟中毒现象。早期地方氟骨症的X线表现:1.骨小梁增粗,边缘模糊呈粗细不等的条状或颗粒状骨
This article reports 161 cases of early local skeletal fluorosis, and 125 cases of healthy controls. Focus on the analysis of the skeleton of the X-ray performance. All patients were school-aged children aged 11-14 years. The fluoride content in drinking water ranged from 4.1 mg / L to 23 mg / L compared with 0.11 to 1.05 mg / L in the control group. Biochemical tests in addition to calcium control group similar to the blood fluoride, urinary fluoride, phosphorus and alkaline phosphatase were higher than the control, urinary fluoride, 12.5 times higher than the control group. Patients had no symptoms, but there are different levels of dental fluorosis, livestock in this endemic area also have serious fluorosis. X-ray findings of early local skeletal fluorosis: 1. Trabecular thickening, fuzzy edge was uneven thickness of the strip or granular bone
