孕期母体血清微量元素含量的研究

目的了解孕妇妊娠各期血清微量元素Zn、Fe、Cu、Ca、Mg的含量.方法采用日本岛津AA-6800型原子吸收仪测定北京地区妇女早孕108例、中孕107例、晚孕108例母体血清中5种微量元素含量,选择62例正常育龄未妊娠妇女血清微量元素含量做对照组进行分析研究.结果血清Zn、Fe、Mg孕期各组均低于非孕期对照组,并随孕周增加而逐渐降低.Cu含量孕期各组均高于未孕组,并随孕周增加而逐渐升高.Ca含量孕期各组与非孕组比较,差异无显著性.可能与孕期孕妇通过药物或饮食调节进行补钙有关.结论孕期动态监测孕妇血清微量元素,以指导不同孕期微量元素补充,对预防不良妊娠结局有重要的临床价值.

Study on the Contents of Trace Elements in Pregnant Women''''s Serum

[Objective] To learn the contents of trace elements as An, Fe, Cu, Ca and Mg in the pregnant women's serum. [Methods] Japanese AA - 6800 Atomic Absorption Apparatus was applied to determine the contents of five trace elements in the serum of 323 pregnant women in different pregnancy stages. 62 healthy women of childbearing age were selected as a control group [Results] The contents of An, Fe and Mg in the case group were lower than that in the control group and decreased with the progressing of pregnancy; the content of Cu in the case group was higher than that in the control group and increased with the progressing of pregnancy; no significant difference was found in the content of Ca, which might be the result of calcium intake of the pregnant women. [Conclusion] It is necessary to make a dynamic determination on the contents of trace elements for pregnant women in order to prevent ill pregnancy result.
