The Morphology of Endocrine Cells in the Gut Mucosa of the Giant Panda

YANG Guibo CHEN Maosheng DENG Zipei WANG Ping(College of Life Sciences , Peking University , Beijing , 100871 )  
Endocrine cells containing 5-hydroxytryptamine,somatostatin , gastrin,cholecystokinin ,neurotensin ,motilin ,gastric inhibitory peptide, glucagon,vasoactive intestinal polypeptide ,and endorphin in the mucosae of the fundus,pylorus ,duodenum,jejunum , ileum, colon ,and rectum of 2 giant pandas were studied by PAP method to gain an insight into the adaptive characteristics for the special feeding habit. The former 8 kinds of endocrine cells were detected in themucosae of the 2 giant pandes.The distribution of cell types categorized by thecytoplasmic process indicated that in the 7-year old giant panda ,the fundicendocrine cells were mostly round or ovoid , apical and basal cytoplasmic processeswere rarely seen; many pyloric endocrine cells pocessed both apical and basalprocesses; while endocrine cells in the small intestine only pocessed apical process.In the 75-day old giant panda, the cell types of the gut endocrine cells are few thanthose of the 7-year old one. These results indicate that the structure and thedistribution of the morphological types of the endocrine cells in the mucosa of thegiant panda might be related to their specific feeding habit.
