Twenty mice were killed 1-6 days after parturition, and the uterine contents were examined grossly and microscopically. Uteri of 10 animals had retained one or more placentas, each of which was firmly attached to the uterus and usually exhibited fetal membranes and an umbilical cord. Histologic preparations revealed that the fetal blood channels in the labyrinth region were collapsed and fibrosed while some maternal blood channels were open and contained blood cells. In the junctional zone and decidua, necrosis and leukocytic invasion were evident. In median sections, a stalk of fibrous tissue extended from the uterus to the placenta.
分娩后1至6天处死20只小鼠，对子宫内容物进行大体和显微镜检查。10只动物的子宫内残留有一个或多个胎盘，每个胎盘均牢固附着于子宫，通常可见胎膜和脐带。组织学切片显示，迷路区的胎儿血窦塌陷并纤维化，而一些母体血窦开放并含有血细胞。在交界区和蜕膜，坏死和白细胞浸润明显。在正中切片中，可见纤维组织束从子宫延伸至胎盘。
