The present study was designed to investigate the morphological developments of the stomach in the prenatal and postnatal rats. The gastric fundus of 16- to 22-day-old fetuses, neonates, 7-day-old, 14-day-old, 21-day-old, and adult rats were observed by light and scanning electron microscopy. Light microscopic studies. 1. In the 16-day-old fetuses, the walls of the gastric fundus were differentiated into epithelium, lamina propria, muscle layer, and serosa. The lamina propria was composed of mesenchymal connective tissue cells with sparse nucleus and their fibers. 2. In the 17-day-old fetuses, the muscular layer were differentiated into the circular and longitudinal muscle layers. 3. The epithelium on the fundus of stomach was stratified columnar cells at 16-, 17- and 18-day-old fetuses, but partly converted into simple columnar epithelium at 19-day-old fetuses. 4. The mucous cells were positive by PAS reaction at the 19-day-old fetuses and then these developed rapidly within 1 or 2 days before birth. 5. In the 20-day -old fetuses, the parietal cells were distinguished from other type cells and these cells were chiefly crowded in the middle parts of the gastric glands after 7-day-old. Scanning electron microscopic studies. 6. The surface of gastric mucosa was covered with forms of the various protrusions by forming villi at the last few days before birth and these protrusion forms were fused and folded each other. 7. The mucosal surface was closely packed by polygonal mucous cells. The openings of gastric glands were seen as slit-like round invagination and were more numerous and increased gradually in depth after the postnatal life. The above findings indicate that prominent changes occurred in the pattern of cellular proliferation in the stomach fundus at the end of gestation. The gastric epithelium had well-defined glands composed of parietal, chief and mucous cells just before the birth. The stomach fundus, therefore, were developed morphologically as those of normal adult at fourteen days after birth.

The present study was designed to investigate the morphological developments of the stomach in the prenatal and postnatal rats. The gastric fundus of 16- to 22-day-old fetuses, neonates, 7-day-old, 14-day-old, 21-day-old, and adult rats were observed by transmission electron microscopy. 1. In the 19-day-old fetuses, the gastric pits and the parietal cells were the primitive state, but the parietal cells contained numerous microvilli and mitochondria. 2. In the 20-day-old fetuses, the intracellular canaliculus appeared in the parietal cells, and glycogen granules were localized mainly in the basal part of the epithelial cells and parietal cells. 3. In the 20-day-old fetuses, the mucous granules and zonular occludens appeared in the gastric glandular cells adjacent to the parietal cells. 4. In the 21-day-old fetuses, the chief cells were identified in the lamina propria and these cells contained granular endoplasmic reticulum and zymogen granules. 5. In the 20- to 22-day-old fetuses, the definitive parietal cells were firstly appeared in pairs or groups within the lamina propria. These cells tended to be placed near the basement membrane and blood capillary, and frequently tended to be extruded into lumen of gland. 6. The endocrine cells were appeared at the basal areas of the gastric gland after the 14-day-old.

A 2-year-old male pseudohermaphrodite in Korean native cattle was observed macroscopically and microscopically. The results were summarized as follows. In the female reproductive organs, the vulva and vestibule were normal size, but the vagina and uterus were shorter and smaller abnormally. The uterine tube and ovary were absent, but the small testes was located in the abdominal cavity.
Histamine이 개의 자궁 평활근 운동성에 미치는 영향

The responses of motility to histamine were investigated with canine uterine longitudinal muscle. The results were summarized as follows: 1. Histamine has been shown to induce contractility with dose-dependent between 10_-7 M and 10_-5 M in canine uterine longitudinal muscle. 2. The contraction induced by histamine was completely blocked by Hi-receptor blocker, chlorpheniramine, at a concentration of 10_-6 M; but was not blocked by H_2-receptor blocker, cimetidine, at a concentration of 5×10_-7 M. 3. The contraction induced by histamine was not blocked by the cholinergic receptor blocker, atropine, at a concentration of 10_-6M. 4. The contraction induced by histamine did not affect adrenergic o-receptor blocker, phenoxybenzamine(10_-6M), and adrenergic β-receptor blocker, propranolol(10_-6M). From these results, it was concluded in dog that the contractility of uterine smooth muscle by histamine was only through H_1-receptor, and that it may not be related to the cholinergic and adrenergic receptor.
