【摘要】 目的 探讨儿童多动症与血铅水平的关系。方法 用原子吸收分光光度法和Conners多动症评分量表分别对儿童多动症(ADHD)组和对照组患儿进行血铅和评分量表测定。结果 ADHD组血铅水平125.85±30.50μg/L，对照组血铅92.60±25.92μg/L，差异有显著性(t＝8.35， P<0.01)，ADHD组儿童铅中毒发生率85.00%(85/100)，对照组42.00%(42/100)，经统计处理两组资料差异有显著性(χ2=38.50， P<0.01)，ADHD组经排铅治疗后血铅水平下降，临床症状缓解，Conners评分明显下降，差异有显著性(t＝16.05， P<0.01)。结论 铅中毒是ADHD病因之一，排铅治疗可以缓解临床症状。

    【Abstract】 Objective To explore the relationship between hyperkinetic disorder in children and their blood lead levels.Methods The measurement of atom-absorbent spectrophotometry and Conners gradet of 100 children with ADHD and 100 normal children.Results The results showed that the content of pb in blood of ADHD was 125.85±30.50μg/L ，that of control group was 92.60±25.92μg/L，Incidence rate of children pb poisoning in ADHD decreased remarkably after curing by removing pb(χ2=38.05，P<0.01).Conclusion It showed that pb poisoning was one of the reason of taking ADHD ......
