| Abstract | This study deals with the histochemical identification of the changing patterns of glycogen in the uterus of the early pregnant and lactating golden hamster (Mesocricetus auratus Waterhouse). The uterus of the hamster representing days one through five of gestation, and one through ten, twelve, and fourteen of lactation, provided the data for this study. Diastase digestion was used on alternate sections of the uterus prior to staining with periodic acid-Schiff, and these sections were compared with adjacent stained sections (untreated with diastase) for assessing the glycogen pattern. The presence and amounts of glycogen in the uterine tissues of both the pregnant and lactating animals are inconsistent. The outer longitudinal myometrium of the pregnancy uteri generally contains more glycogen than the inner circular myometrium, whereas these two layers in the lactation uteri usually contain equal amounts. Granular glycogen in the endometrium was seen only during gestation and solely on the fifth day, on which it is restricted to the locular level of the uterus and in very dense deposits. The uterine epithelium proper contains granular glycogen in small amounts on some days of gestation, but none occurs in the lactation uteri. Although the associated basement membrane never contains granular glycogen, the diffuse form is present but rather inconsistently. The epithelial border of the pregnancy uterus contains patches of glycogen granules with greater frequency than does that of the lactation uterus. Seldom does glycogen occur in the uterine lumen but when it does, it is always in patches. The epithelium and lumen of the uterine glands contain small amounts of granular glycogen on some days of pregnancy whereas, with one exception, neither of these areas in the lactation uteri have granules. Diffuse glycogen in varying amounts commonly occurs in the basement membrane associated with the uterine glands. Whereas the tunic of the veins during pregnancy contains more granular glycogen than does the tunica media of the arteries, only diffuse glycogen was noted in these tunics of the lactation uteri and in equal amounts. A comparison is made between current observations on the hamster and those made by others not only in the hamster but also on other species. |
