【摘要】 目的探讨反复呼吸道感染儿童血清微量元素、铅与免疫功能的相关性;方法选取100例反复呼吸道感染儿童,对其进行血清锌、铁、钙、铅和IgA、IgE、IgG、IgM的测定,并对结果进行相关性分析;结果血清IgG分别与锌、铁呈显著正相关(r=0.551、r=0.412,P<0.01),血清IgE与血清铁呈显著负相关(r=-0.449,P<0.01),血铅与血清IgA呈显著负相关(r=-0.573,P<0.01);结论血清铁、锌缺乏、铅含量过高对机体免疫功能有一定影响,可不同程度的造成免疫功能下降,在反复呼吸道感染发生发展过程中具有重要意义。更多还原

【Abstract】 Objective:To explore the relativity of blood microelement,lead and immune function about RRI in children.Methods:We selected 100 children who belonged to RRI,they were implemented laboratory check about zine,iron,calcium,lead and IgA,IgE,IgG,IgM in blood.Results: There was a positive relativity between IgG and zinc,iron in blood significantly,the relation of IgE in blood and iron was negative relativity significantly,there was a significant negative relativity between IgA and lead in blood too.Conclusion:The deficiency of iron,zinc in blood and excessive lead in blood would lead to the letdown of immune function.So it has a significant meaning in the course of RRI.更多还原
