用水牛9头,黄牛、猪、狗各3头,顺序取消化道12个部位,切片观察结果,水牛消化道嗜银性内分泌细胞比其他动物多,草食动物的胃和直肠细胞数比杂食动物和肉食动物都多。草食动物从胃和小肠这两个部位开始,嗜银性内分泌细胞都多,向后逐渐减少。胃肠道内分泌细胞多为单个,分散的夹杂在腺上皮细胞之间。此项内分泌细胞分布于每个腺管的中部或基部,向腺管顶端渐少,胃的内分泌细胞多为圆形,嗜银颗粒均匀分布于核周围;而肠的内分泌细胞多为锥形,颗粒集中于细胞基部,顶端逐渐稀疏。
9 buffaloes, 3 cattle, 3 pigs and 3 dogs were randomly divided into 12 parts. The results showed that there were more argyrophilic endocrine cells in buffalo gastrointestinal tract than those in other animals. The numbers of stomach and rectum cells in herbivores were higher than those in omnivores And carnivores are more. Herbivore from the stomach and small intestine in these two parts began, more than the silver-rich endocrine cells, backward gradually reduced. Gastrointestinal endocrine cells are mostly single, scattered between the glandular epithelial cells. The endocrine cells are located in the middle of each duct or base, to the top of the duct diminished, mostly gastric endocrine cells round, uniform distribution of argyrophilic granules around the nucleus; and intestinal endocrine cells mostly conical, Particles concentrated in the base of the cell, the top gradually sparse.
