母血中常、微量元素与胎儿宫内发育迟缓关系的研究

目的：探讨常、微量元素与胎儿宫内发育迟缓（IUGR）间的关系。方法：于孕晚期测定了71名孕妇母血、脐血、羊水中微量元素水平,其中IUGR组21例,对照组35例,巨大儿组15例。结果：IUGR组母血清Zn、Se、Mn、Fe、Mg、Cr明显低于对照组（P〈0.05）;Cd、Pb、Ni水平明显高于对照组及巨大儿组;其中,巨大儿组母血清Fe含量亦明显低于对照组（P〈0.05）Ca、Ti、Co、Li三组问无明显差别。IUGR组脐血清Se、Mn、Cd、Fe、Cu、Mg明显低于对照组;Pb、Ni明显高于对照组;Zn、Ca、Ti、Co、Li三组间无明显差别。IUGR组羊水中Zn、Se、Mn、Fe明显低于对照组及巨大儿组,Ca、Co三组问无明显差别。结论：某些常、微量元素与胎儿发育关系密切,其中Zn、Se、Mn、Fe、Mg、Cu、Cr缺乏可致胎儿宫内发育迟缓,而Cd、Pb、Ni升高亦可致低体重儿。

TELATIONSHIP BETWEEN MACRO-AND MICRO-ELEMENTS AND IUGE

Objective:To explore relationship between macro-and micro-elements and intrauterine r growth retardation.Methods:Microelements were analyzed in maternal blood,fetal serum,and amniotic fluid of 71 gravidasd during late pregnancy,of which IUGR group 21,normal birth weight group 35(control group),and macro-somia group 15.Results:In maternal blood of IUGR group.the levels of Zn,Se,Mn,Fe,Mg,and Cr were significantly lower than those in control group.The levels of Cd,Pb,and Ni were significantly higher than those...
