黄羊胃肠组织形态学研究

采用石蜡切片方法对健康成年黄羊胃，肠进行了组织形态学观察。结果表明，瘤胃，网胃和瓣胃的胃壁构造基本相同。粘膜上皮都是复层扁平上皮，浅层细胞角化，瘤胃粘膜上形成许多大小不等的舌状乳头。无粘膜肌层；网胃粘膜形成许多皱襞。在皱襞上和网孔底上有许多圆锥状乳头。

Study on Gastrointestinal Tissue Morphology for Procapra gutturosa Paclas

The tissue morphology of stomach and intestine for healthy adult Procapra gutturosa Paclas wereobserved by means of paraffin section. The results show that the structure of stomach wall of firststomach. reticulo-rumen and omasum are approximately similar, their membrana mucosa are all multistratified squamous epithelium with keratinised cell. Maly linguiform Papillas in different size areformed on the first stomach mucosa, without muscularis mucosa; the mucosa of reticulo-rumen forms alot of folds. on which there are many Papillas conicae. vertically patched crests exist on both sides ofreticulo-rumen fold. manifold mucosa forms many folds in different length. coarse and short papilla canbe seen on both sides of folds. muscularis mucosa of omasum is well-developed. central muscularislayer and muscularis mucosa are vertical in large fold. There is no glandular secretion in membranapropria of these three stomaches. Abomasum mucosa is smooth, 13 ~ 16 spiral big fold in fundus glandregion mucosa. membrana mucosa is composed of simple columnar epithelium, membrana propria is well-developed hold by concentrated fundus gland. but the glandular vessel is very short. There is smallintestinal glade and lymphoid tissue in membrana Propria, duodenum mucosa sublater is duodenalgland. large intestine mucosa is smooth without circular folds and villus intestinalis. There is largeintestine gland in membrana propria. the intestinal gland is composed of simple columnar cell and beaker cell.
