本文采用火焰原子吸收分光光度法（ＦＡＡＳ）检测长春地区１１７例不同孕妇血清及其新生儿脐血清和胎盘组织中铁（Ｆｅ）、锌（Ｚｎ）含量，获得正常足月孕妇血清及其新生儿脐血清以及胎盘组织中铁、锌含量的正常范围；且证明妊娠后孕妇血清中铁含量较未孕妇女血清铁含量高，血清锌含量明显降低；而新生儿脐血清铁、锌含量均因胎盘主动转运明显高于孕妇血清铁、锌含量，且受病理妊娠所影响；而各组间胎盘组织中的铁、锌含量无显著差异。
In this paper, FAAS was used to detect the contents of iron (Fe) and zinc (Zn) in umbilical serum and placenta from 117 pregnant women and their newborns in Changchun area, Serum and placental tissue iron and zinc content of the normal range; and pregnant women after pregnancy proved iron serum iron levels higher than the serum of pregnant women, serum zinc levels decreased significantly; neonatal umbilical cord serum iron and zinc levels were significantly due to the placenta was actively transported Which was higher than that of serum iron and zinc in pregnant women and was affected by pathological pregnancy. There was no significant difference in the content of iron and zinc in placenta between groups.
