| 中文摘要: |
| 为了探讨极北鲵(Salamandrella keyserlingii)消化道嗜银细胞的胚后发生及其形态和分布,试验采用Grimelius银染法对其进行了研究。结果表明, 嗜银细胞在食管、胃、小肠各部分的发生时间不同,出现最早的是胃中的嗜银细胞,在胚后发育的第41期首先出现,其次是小肠中的,在第42期开始出现,最晚的是食管中的,在第43期才开始出现。嗜银细胞形态多样,有圆形、椭圆形、梭形和锥体形,大多分布在消化道粘膜上皮之间。根据嗜银细胞的形态,认为其具有内分泌和外分泌的功能。 |
| 英文摘要: |
| Morphology and distribution of Argyrophil cells in the digestive tract in the postembryonic development of Salamandrella keyserlingii were investigated by means of silver nitrate method of Grimelius. The result showed: Argyrophil cells first appeared between mucous epithelial cells in the stomach of Salamandrella keyserlingii at stage 41 in round, oval, as well as conical shapes, with their processes extending to nearby cells. Argyrophil cells were first observed in the intestine at stage 42. They mainly distributed between epithelial cells in cone-shape or shuttle-shape. Argyrophil cells appeared in the esophagus as late as stage 43. They mainly distributed between epithelial cells in various forms. According to the morphology of the argyrophil cells, they have endocrine and exocrine functions. |
