为了探讨儿童铅中毒对其远期肾功能的影响,作者调查74例患者和21例配对对照组的肾功能。患者在1966～1972年(年龄1～6岁)患有铅中毒症,血铅(PbB)水平≥100μg/dl(范围为100～471μg/dl,均值为142 μg/dl),经驱铅后PbB降低到50μg/dl以下。21名对照者的PbB<40 μg/dl。1983年对患者组和对照组进行体重、身高、尿分析和肾功能试验等检查。结果:两组的PbB水平很低,患者组的PbB均值为14.5±4.5 μg/dl,对照组PbB的均值为11.6±2.6μg/dl,两组有显著差异(P<0.01)。患者组和对照组的血尿或白细胞
To explore the impact of childhood lead poisoning on its long-term renal function, the authors investigated renal function in 74 patients and 21 matched controls. Patients with lead poisoning, PbB levels ≥100 μg / dl (range, 100-471 μg / dl, mean 142 μg / dl), from 1966 to 1972 (ages 1-6) PbB reduced to 50μg / dl or less. Twenty-one controls had PbB <40 μg / dl. In 1983 the patient group and control group weight, height, urinalysis and renal function tests and other tests. Results: The PbB level in both groups was very low. The average PbB level in the two groups was 14.5 ± 4.5 μg / dl. The mean PbB level in the control group was 11.6 ± 2.6 μg / dl. There was significant difference between the two groups (P <0.01). Hematuria or leukocytes in patient group and control group
