| 摘 要： | 目的:应用5-羟色胺(5-HT)抗血清研究非洲爪蟾消化道内的5-HT免疫活性细胞的分布密度及形态,并探讨其分布型的成因及细胞形态与功能的关系。方法:免疫组织化学ABC法。结果:5-HT细胞在非洲爪蟾消化道的各个部位均有分布,分布密度近似呈M形,其中以空肠分布密度最高,胃贲门部次之,食管最低。5-HT细胞的形态多样,呈圆形、椭圆形、锥体形等,主要分布于消化道黏膜上皮细胞之间、上皮基部、同有膜以及腺泡上皮细胞之间等。结论:非洲爪蟾消化道5-HT细胞具有内、外分泌2种功能。

| Abstract: | Objective:To study the distribution and density of 5-HT cells in the digestive tract of XenopusLaeuis with anti-5-HT-serum,and the relations between morphology of endocrine cells and function and origins of distributive mode.Methods:ABC(avidin-biotin complex method)immunhistochemical technique was used.Results:From the e- sophagus to the rectum 5-HT cells distributed universally,with an"M"pattern in density.The density of 5-HT cells was the highest in the jejunum,the second in the cardiac part and the lowest in the esophagus.Round,ellipse or cone- shaped 5-HT cells were distributed between the epithelial cells,at the basal region of epithelial cells,in the lamina pro- pria,and between the glandular epithelial cells.Conclusion:5-HT cells in the digestive tract of Xenopus Laeuis have both endocrine and exocrine functions. |
