This present study was designed to investigate by light microscope the morphologic changes in the uterine and vaginal epithelium of postpartum Korean native goats. Tissues were obtained for study on days 1, 3, 10 and 21 postpartum. The results obtained in this study were as followed; 1. Light microscopically, the height of the uterine epithelium was gradually decreased with the intervals and secretory profiles of apocrine were observed at between 1 and 10 days postpartum. The frequency of the light and dark cells with Masson’s trichrom stain was high at 1 day postpartum an low at 21 days. A few of PAS positive cells were generally observed at 1 day postpartum, while PAS positive cells were not seen at 21 days. Numerous globule leucocytes were found between the epithelium and in the subepithelium at 1 day and thereafter moderate globule leucocytes were also found in the other periods. The intraepithelial vacuoles with crystalline structure appeared at 10 days postpartum. 2. The height of the vaginal mucosa was gradually decreased with the intervals but the highest layer was found at 3 days postpartum. The frequency of the mast cells was increased with times. At 3 and 10 days postpartum the shape of the surface-epithelium was cuboidal and the vacuolation of the epithelium was observed at 10 and 21 days.
