One hundred sixty one placentae were examined grossly and microscopically, 131 specimens belonged to seropositive patients and 30 specimens belonged to seronegative patients and used as control. 63.3% of the placentae of seropositive patients were macroscopically normal, 9% were hydropic, 21% were of mixed or partially hydropic pattern, 6% had areas of infarction & 0.7% showed areas of calcifications. The most consistent microscopic finding was focal low grade chronic villitis with mononuclear inflammatory infiltrate. In hydropic placentae villous edema was of very variable degree from one placenta to another and from one area to another in the same placenta. Nucleated red blood cells were demonstrated in villous capillaries. The patients had Rh positive factor in their blood.
对161个胎盘进行了大体和显微镜检查，其中131个标本来自血清阳性患者，30个标本来自血清阴性患者并用作对照。血清阳性患者的胎盘中，63.3%大体正常，9%为水肿型，21%为混合型或部分水肿型，6%有梗死区域，0.7%有钙化区域。最一致的显微镜下表现是局灶性低度慢性绒毛炎伴单核细胞炎性浸润。在水肿型胎盘中，绒毛水肿程度在不同胎盘之间以及同一胎盘的不同区域之间差异很大。在绒毛毛细血管中发现了有核红细胞。这些患者血液中具有Rh阳性因子。
