细胞凋亡是在各种不同生理和病理条件下发生的一种十分重要的生物学现象。对胎盘细胞凋亡过程的研究虽处于早期阶段,但进展很快。本研究首先假设子宫内生长迟缓(IUGR)的胎盘细胞凋亡的发生率较高,可能是引起IUGR的一个原因。本文目的在于探索胎盘细胞凋亡在IUGR发病机制中的可能作用。方法:胎盘标本取自43例无宫内感染无并发症的晚期妊娠妇女和26例晚期妊娠合并IUGR患者,随机选择正常对照 Apoptosis is a very important biological phenomenon that occurs under a variety of different physiological and pathological conditions. Although the research on the process of placental apoptosis is at an early stage, it has progressed rapidly. This study first assumed that a high incidence of placental apoptosis in intrauterine growth retardation (IUGR) may be one of the causes of IUGR. The purpose of this paper is to explore the possible role of placental apoptosis in the pathogenesis of IUGR. Methods: The placenta specimens were obtained from 43 pregnant women without complications of intrauterine infection and 26 with IUGR in late pregnancy. Randomly selected normal controls
