妊娠贫血与胎盘重量

Pregnant Anemia and Placental Weight

用相关与回归分析的方法研究647例妊娠末期孕妇血液中血红蛋白浓度与胎盘重量之间的关系，并对贫血与非贫血孕妇的胎盘平均重量进行了比较。结果显示女婴组血红蛋白浓度与胎盘重量呈负相关，而男婴组两者却无显著性相关关系。表明在妊娠贫血时，女性胎儿可通过胎盘肥大进行代偿，男性胎儿的胎盘无明显肥大，可能主要通过增强胎盘功能进行代偿。

Prepartal blood hemoglobin (Hb) level and placental weight from 647 cases were put to correlation and regression analysis,and the average placental weight of anemic and nonane-mic gravidas were compared by u test- The results showed that the Hb level of gravidas was negatively correlation with placental weight in female newborn group,but there is no signifi-cant correlation in male newborn group. It indicates that the female fetus may be compensat-ed by placental hypertrophy and the male fetus may be compensated by strenthening placen-tal function,as mother anemia.
