Abstract：The distributed density and morphology of argentaffine cells in the digestive tract of Gloydius shedaoensis Zhao were studied using the silver nitrate method of Grimelius. The results indicated that argentaffine cells distributed widely in the digestive tract, from esophagus to rectum. The distributed density of argentaffine cells was the highest in cardiacpart of stomach, the second in body of stomach part and the lowest in esophagus. They were found in between epithelial cells, at the basal region of epithelial cell, between glandular epithelial cells, and a few in lamina propria. The shape of argentaffine cells was diverse, such as cone-shape, spindle, round and ellipse. According to its morphology, argentaffine cells in the digestive tract is suggested to have endocrine and exocrine functions.
