【摘要】 本文报道70例妊高征胎盘床活检的组织形态学,并与110例正常妊娠胎盘床活检进行对照。结果显示妊高征胎盘床蜕膜段与蜕-肌段螺旋动脉的病理性改变较正常组增高;妊高征组蜕-肌段螺旋动脉的生理性变化较正常组减少,P<0.001。但国外某些学者认为妊高征普遍存在的特有的急性动脉粥样化却罕见,提示妊高征胎盘床不一定具有特征性的动脉病变。其次,妊高征组半数以上肌层内血管周围有灶性淋巴细胞浸润,与正常组比较有显著差异,可能与细胞免疫有关。更多还原

【Abstract】 The histomorphology of 70 cases of placental bed biopsy in pre-eclampsia andeclampsia was examined,and compared with 110 cases of placental bed biopsy in normalpregnancy.The data demonstrated the frequency of pathological changes of spiral arteriesin decidual segment and decidual-myometrial segment in pre-eclampsia and eclampsiawas higher than that of the control group,and the frequency of the physiologicalchanges of spiral arteries in decidual-myometrial segment was less than that of thecontrol group(P<0.001).However,the so called characteristic acute atherosis wasrare,indicating that the characteristic arteriopathy of placental bed in pre-eclampsiaand eclampsia was infrequent.There was perivascular lymphocyte infiltration in myo-metrium in more than half of pre-eclampsia and eclampsia cases,which showed a significantdifference as compared with the control group.Probably it is related to cell-mediatedimmunity.更多还原
