泥鳅消化道6种内分泌细胞的免疫组织化学定位(英文) 总被引：1，自引：0，他引：1
[Objective] The study was to immunohistochemical localize the endocrine cells from digestive tract of Misgurnus anguillicaudatus.[Method] Using six gastrointestinal hormone antisera, the endocrine cells from digestive tract of M.anguillicaudatus was immunohistochemical localized.[Result] The 5-hydroxytryptamine immunoreactive(5-HT-IR) cells distribute in oesophagus, foregut and midgut; the distribution density was determined to be forepart of foregut> oesophagus and hindpart of foregut>gut, and the differences in the three density gradients reached significant level. Like PP-IR, SS-IR cells were observed mostly in oesophagus, followed by hindpart of foregut, least in forepart of foregut, but never found in gut and hindgut. The three kinds of immunocompetent cells Gas-IR, Glu-IR and SP-IR were not detected in each part of digestive tract. [Conclusion] This study may provide basic data for studying the nutritional and digestive physiology, as well as the preparation of meridic diets for M.anguillicaudatus. 相似文献

[目的]对泥鳅胃肠道内分泌细胞进行免疫组织化学定位研究。[方法]应用6种胃肠激素抗血清对泥鳅（Misgurnus anguillicaudatus Cantor）消化道内分泌细胞进行了免疫组织化学定位。[结果]5-HT-IR细胞分布在泥鳅消化道的食管、前肠和中肠。以前肠前段密度最高,食管和前肠后段其次,中肠最少,分布差异显著;SS—IR和PP—IR细胞相同,主要分布于食管和前肠,食管段最多,前肠后段较少,前肠前段最少,中肠和后肠中未见分布;Gas—IR、Glu—IR和SP—IR3种免疫活性细胞在消化道各段均未分布。[结论]泥鳅消化道内这6种内分泌细胞分布和其他鱼类比较,既显示了鱼类消化道内分泌细胞分布的共性,又显示了一定的种间差异。 相似文献
