Tissue samples from a therapeutic curettage performed in a woman with acquired immunodeficiency syndrome and a semen sample of the husband were studied with the electron microscope. The samples were processed according to routine technique for electron microscopy. Calcifications, basement membrane thickening and hyperplasia of Hofbauer cells were seen in the placenta villi. Electron-dense particles of unknown nature, probably of viral origin, were found on the fetal red blood cell membranes, virus-like particles were identified in the endothelial cell nucleus of the brain and lung. Retrovirus-like particles were found in the protein of the seminal plasma. These results suggest that the retrovirus pass through the placenta during early pregnancy.
对一名患有获得性免疫缺陷综合征的女性进行治疗性刮宫获取的组织样本以及其丈夫的精液样本进行了电子显微镜研究。样本按照电子显微镜的常规技术进行处理。在胎盘绒毛中可见钙化、基底膜增厚和霍夫鲍尔细胞增生。在胎儿红细胞膜上发现了性质不明的电子致密颗粒，可能起源于病毒，在脑和肺的内皮细胞核中鉴定出病毒样颗粒。在精浆蛋白中发现了逆转录病毒样颗粒。这些结果表明逆转录病毒在妊娠早期穿过胎盘。
