摘要
目的 探讨铅作业工人肾脏损害的早期指标及其临床意义。方法 80名铅作业工人分为铅接触正常组、铅吸收组、慢性轻度铅中毒组 ,并以无铅接触史的 43名健康成人作为对照组。分别测定血铅 (PbB)、尿铅 (PbU)、血红细胞游离原卟啉 (FEP)、尿δ 氨基酮戊酸 (δ ALA)、尿 β2 微球蛋白 ( β2 MG)、尿N 乙酰 β D 氨基葡萄糖苷酶(NAG)、尿视黄醇结合蛋白 (RBP)。结果 铅作业工人PbB、PbU、FEP、δ ALA、NAG、RBP均显著高于对照组 ;β2 MG虽亦高于对照组 ,但差别无显著性。结论 长期职业性铅接触可造成肾功能损害 ,尿NAG。
Objective To study the early indices of renal damage in lead workers and its clinical significance.Method 80lead workers were divided into the exposure group,the lead-absorption group and the chronic mild poisoning group,another43persons with-out lead exposure were the controls.The results of PbB,PbU,FEP levels and the urinary contents ofδ-ALA,NAG and RBP were all analyzed.Result The levels the PbB,PbU,FEP,δ-ALA,β 2 -MG,NAG and RBP in lead workers were significantly higher than that of the control,butβ 2 -MG levels had no significant difference.Conclusion Long-term exposure to lead could cause renal function-al damage,and the levels of NAG,RBP might be sensitive indicators for early renal functional damage.
