|
The morphological changes of the enterochromaffin cells in the gastrointestinal mucosae of Rana amurensis were observed during pre-hibernating, hibernating, post-hibernating and active period. The results of the observation are as follow: 1. The relative values of the enterochromaffin cell numbers in the pre-hibernating, hibernating and post-hibernating groups as compared with the active group are 1.50, 0.36 and 0.90, respectively. 2. In active and pre-hibernating groups, the enterochromaffin cells are large and middle-amount granulated cells and the sparse granulated cells increase significantly during hibernating and post-hibernating periods. 3. It is concluded that the morphological changes of enterochromaffin cells are due to lowered metabolic acitvities especially lowered endocrine activity during hibernation.
