Ninety-two placentas from patients with late toxaemia of pregnancy were studied by means of histologic, stereologic and enzyme histochemical methods. 32 placentas were from live births and 60 from stillbirths. In the stillbirth series, 31 placentas were from cases of fetal antepartum deaths and 29 from cases of fetal intrapartum deaths. The increase of the microcirculation volume in placental villi and the increase of oxidative enzyme activity in the syncytiotrophoblast, stroma and villi vesel wall are considered as structural and metabolic mechanisms of placenta adaptation. The role of structural and metabolic placenta insufficiency in the pathogenesis of the intrauterine fetal death is discussed.
采用组织学、体视学和酶组织化学方法对92例妊娠晚期中毒症患者的胎盘进行了研究。32例胎盘来自活产，60例来自死产。在死产组中，31例胎盘来自胎儿产前死亡病例，29例来自胎儿产时死亡病例。胎盘绒毛微循环量的增加以及合体滋养层、间质和绒毛血管壁氧化酶活性的增加被认为是胎盘适应的结构和代谢机制。讨论了胎盘结构和代谢功能不全在胎儿宫内死亡发病机制中的作用。
