脐血及母血10种元素的测定分析

目的了解脐血及母血中微量元素水平。方法采用原子吸收光谱法对532名健康新生儿脐血及其母血进行10种元素测定。结果不同性别新生儿脐血中Fe、As含量不同，男高于女（P＜0．05）；脐血中Fe、Ca含量明显高于母血，而Zn、Cu含量明显低于母血（均为P＜0．01）；Mg、P、K、Mn、Se、As含量相差无显著性（P＞005）。结论不同性别胎儿对微量元素需求不同，且新生儿体内微量元素分布与母体并不完全一致；胎盘有其独特的主动转运功能；脐血检测具有实用性。

THE DETECTION AND ANALYSIS OF THE TEN TRACE ELEMENTS IN FETAL AND MATERNAL BLOOD

In order to study the amount of the trace elements in fetal blood and maternal blood. Method Detection and analysis were performed on the ten elements in fetal blood of 532 normal neonates and their maternal blood by using atomic spectrometry. Result A difference was shown in the amount of Fe and As between male and femal neonates, with the formor greater than the latter (P<0. 05); the amount of Fe and Ca in fetal blood was much more greater than that in maternal blood (P<0. 001); the content of Zn and Cu in the fetal blood was less greater than that in the maternal blood (P<0. 001); there was no significant difference in Mg, P, K Mn. Se. and As between fetal blood and maternal blood (P>0. 01). Conclusion It demonstrates that the need for trace elements is different between male fetus and femal ones. The ampunt of trace elements in fetal blood is not all consistent with that in maternal blood. The placenta has specific active transport function, so it is useful to detect fetal blood.
