摘要
目的探讨不良妊娠胎儿的发生与其母亲体内部分必需营养素及重金属含量的关系。方法分析5～8个月龄先天性畸形胎儿和难免流产胎儿大脑、臀肌、胸腺、枕骨、肝脏组织及与其相关的母亲血、脐血、胎盘中钙、锌、铜、铁、硒、铅、镉、汞以及其母亲血、脐血中维生素A的含量,并与正常对照组比较。结果除先天性畸形胎儿组中的铁偏高外,其余血液及各组织中必需营养元素钙、锌、铜、铁、硒和维生素A含量普遍偏低,在母血、脐血和胎盘及胎儿肝脏中差异显著(P<0.05);重金属铅、镉、汞含量普遍较高,在胎盘、胎儿肝脏和枕骨等组织中差异显著(P<0.05)。结论不良妊娠胎儿的发生与部分必需营养素的缺乏及重金属的积蓄有关。
Objective To study on the relationship between contents of partial necessary nutrition elements, heavy metals in fetus, monther and occurrence of ill pregnancy. Methods The contents of many kinds of elements such as Ca,Zn,Cu,Fe,Se,Pb,Cd, Hg were respectively detected in cerebra, gluteu, thymus, occipital bone, liverof congenital malformed and inevitable abortion foetus at the age of five to eight months and correlative gravida＇s blood, umbilic blood, placenta, and the contents of vitamin A from gravida＇s blood and urnbilic blood. The results were compared with control group. Results In group of ill pregnanted fetus, the contents of necessary nutrition elements in blood and tissue were all lower except that Fe in the group of congenital malformed foetus was high. The variation was especially evident in gravida＇s blood, umbilic blood, placenta, and liver of fetus. The contents of heavy metals such as Pb, Cd, Hg were all higher, and the variation was evident in placenta, liver of fetus and occipital bone. Conclusion The delivery of fetus with ill pregnancy has a close relation with lack of partial necessary nutrition elements and accumulation of heavy metals.
