【摘要】 本文用免疫组织化学方法（ＰＡＰ法）对１０种ＧＩＥＣ在中华竹鼠（Ｒｈｉｚｏｍｙｓｓｉｎｅｎｓｉｓ）１５个胃肠段中的分布作了观察和统计分析，以探讨中华竹鼠胃肠内分泌细胞与其特殊食性的适应关系．结果表明：中华竹鼠胃肠中可能至少有７种免疫反应活性内分泌细胞。与大熊猫相比，尽管都以竹类为主食，但由于取食行为不同，它们ＧＩＥＣ的分布型不尽相同．这些结果从一定程度上表明ＧＩＥＣ的分布不仅与食物组成相关。也可能与取食行为有关。更多还原

【Abstract】 Somatostatin, gastrin, cholecystokinin, neurotensin, motilin, gastric inhibitory polypeptide, glucagon, vasoactive intestinal peptide, endorphin and 5-hydroxytryptamine immunoreactive cells in the mucosae of 15 segments of the gastrointestinal tract of each of the 5 Chinese bamboo rats(Rhizomys sinensis)were studied in order to delineate their adaptation to the special feeding behavior. 7 kinds of endocrine cells were found except motilin, vasoactive intestinal peptide and endorphin immunoreactive cells.The distribution of these cells was compared with that of the giant panda. Although both the bamboo rat and the giant panda live on bamboos, yet the kind and distribution of endocrine cells in their gastrointestinal mucosa are different because of the differences in feeding behavior, i. e.the bamboo rat grinds its food into dust while the giant panda does not. These data indicate that the distribution of gastrointestinal endocrine cells related not only to the composition of what the animals live on but aslo to how the animals process their feed before swallowing down.更多还原
