[摘要] 目的 探讨反复呼吸道感染(RRTI)患儿血清微量元素的含量及其比值的临床意义。方法 采用原子吸收光谱法，测定50例RRTI患儿、52例健康儿童血清微量元素锌、铜、铁、钙、镁的含量，并计算它们的比值。结果 与健康儿童比较，RRTI患儿血清铁明显降低(P<0.01)，血锌降低(P<0.05)，血铜升高(P<0.05)；RRTI患儿血清Cu/Zn、Cu/Fe、Ca/Mg比值升高，差异有显著性。结论 血清铁、锌、铜的变化可能与RRTI的发作有关，在RRTI的防治中应注意微量元素的平衡，适当补充铁、锌制剂。[关键词] 呼吸道感染；微量元素；儿童

[Abstract] Objective To investigate the change of trace element in the serum of children with recurrent respiratory tract infection(RRTI).Methods Using atomic absorption spectrophotometer,we tested the content of zinc(Zn),copper(Cu),iron(Fe),calcium(Ca)and magnesium(Mg)in the serum in 50 cases of children with RRTI and 52 healthy children,counted their ratios.Results In RRTI group,the count of Fe was significantly lower than that in the control group(P<0.01),and so was Zn(P<0.05),the count of Cu was much higher than that in the control group(P<0.05).In RRTI group,the rate of Cu / Zn,Cu/Fe,Ca/Mg were significantly higher than that in the control group.Conclusion The change of Fe,Zn,Cu in the serum may had relations with RRTI.The balance of trace element should be recognition and to supplement Fe and Zn can reduce the frequency of RRTI. ......
