探讨正常妊娠中微量元素的变化,对妊娠早、中、晚期孕妇体内的微量元素进行测定,并与育龄非孕期妇女进行对照。结果提示:血清Zn孕期呈明显下降趋势,而红细胞Zn在妊娠早、中期与对照组一致,孕晚期明显上升;血清Cu和CP随着孕周增加而升高,分别为对照组的1.99倍和1.46倍;血清Fe孕早期明显下降,孕中期晚期有回升但仍低于对照组(P<0.05),而铁蛋白高于对照组,以孕早期为最高。结果说明孕期必须注意补充必需的微量元素。
To explore the changes of trace elements in normal pregnancy, to measure the trace elements of pregnant women in early, middle and late pregnancy, and to compare with non-pregnant women of childbearing age. The results showed that the serum Zn decreased significantly in the first trimester of pregnancy, while the red cell Zn was consistent with the control group in the early and middle third trimester of pregnancy and significantly increased in the third trimester. The levels of serum Cu and CP increased with gestational weeks increasing, which were 1.99 and 1.46-fold; serum Fe decreased significantly in early pregnancy, pregnant in late pregnancy but still lower than the control group (P <0.05), while the ferritin higher than the control group, the highest in the first trimester. The results show that during pregnancy must pay attention to the necessary trace elements.
