An histological study of the postpartum period in 29 mares was carried out. Uterine biopsies were taken daily during the first 10 days postpartum in a total of 87 samples. At day 0, equine endometrium was characterized in the surface by the presence of regularly ordered microcaruncles; the stratum spongiosum was oedematous and contained distended and scarce glands. Degenerative changes in microcaruncles and endometrial glands were present on day 1 postpartum. The epithelium of the microcaruncles from 2 to 5 days postpartum showed cytoplasmic vacuolization, karyorrhexis and an inflammatory reaction with neutrophils and phagocitic cells. On day 7 postpartum, the histology of the endometrium was similar to the normal proestrus with cuboidal luminal epithelium and an oedematous stromal tissue. The changes are usually completed within days 9 and 10 postpartum with the histologically typical appearance of estrus in mares.
对29匹母马的产后时期进行了组织学研究。在产后的前10天每天进行子宫活检，共采集了87个样本。在第0天，马子宫内膜表面的特征是存在规则排列的微肉阜；海绵层水肿，含有扩张且稀少的腺体。产后第1天，微肉阜和子宫内膜腺体出现退行性变化。产后2至5天，微肉阜的上皮细胞出现细胞质空泡化、核固缩，并伴有中性粒细胞和吞噬细胞的炎症反应。产后第7天，子宫内膜组织学与正常发情前期相似，管腔上皮为立方形，间质组织水肿。这些变化通常在产后第9天和第10天内完成，此时母马子宫内膜呈现出组织学上典型的发情外观。
