| 摘 要： | 用S－P免疫组织化学的方法对无斑肥塬消化道五－羟色胺（5－HTIR）免疫活性细胞的分布及形态进行了观察。结果表明，5－HTIR细胞从食道到直肠的消化道各段均有分布。其中，幽门部密度最高，十二指肠次之，直肠最低。5－HTIR细胞形态多样，有圆形、梭形、纺锤形或烧瓶形，梭形、纺锤形或烧瓶细胞有较长的胞突，有时胞突可见明显分叉。同时讨论了5－HRIR细胞的分点特点、形态与功能的关系。

| Abstract: | Distribution and morphology of 5-Hydroxytryptamine immunoreactive(5-HTIR) cells in the digestive tract of Pachytriton labiatum were investigated by immunohistochemical method.The result showed:5-HTIR cells distributed throughout the digestive tract, from esophagus to rectum,with the highest density in the stomachus pyloricus, the second highest in the duodenum and the lowest in the rectum.5-HTIR cells assume various forms, such as round, spindle or flask-shaped.Spindle and flask-shaped cells have processes in one or both ends,some process forks in the end.The characteristic of distribution and the relationship between morphology and function were discussed. |
