Light and electron microscopy were used to study the morphology of uterine luminal epithelium from 4 or 5 gilts slaughtered on each of days 10, 13, 16, and 19 of the estrous cycle. Ultrastructural evidence indicated that metabolic activity and accumulation of glycogen by the uterine epithelium increased between days 10 and 16 of the estrous cycle. This phase of high synthetic activity had been terminated by day 19, as evidenced by the reduction or absence of glycogen deposits and decreased incidence of organelles associated with synthetic activity. Diffuse degeneration of epithelial cells occurred throughout the period of study but was maximal between days 16 and 19. Mitotic activity indicated that cell replacement also occurred between day 16 and day 19.
利用光学显微镜和电子显微镜研究了发情周期第10、13、16和19天屠宰的4或5头后备母猪子宫腔上皮的形态。超微结构证据表明，发情周期第10天至16天期间，子宫上皮的代谢活性和糖原积累增加。到第19天，这种高合成活性阶段已经结束，糖原沉积减少或消失以及与合成活性相关的细胞器发生率降低证明了这一点。在整个研究期间，上皮细胞均发生弥漫性变性，但在第16天至19天最为明显。有丝分裂活性表明，细胞更替也发生在第16天至19天之间。
