摘要
用S P免疫组织化学的方法对无斑肥螈消化道五 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、纺锤形或烧瓶形细胞有较长的胞突 ,有时胞突可见明显分叉。同时讨论了 5 HTIR细胞的分布特点、形态与功能的关系。
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.
