For the purpose of comparing the number of enterochromaffin cell (EC cell) between the prehypertensive stage of SHR and normotensive WKY, the EC cell of the intestine was examined under the light and electron microscopy. The number of argyrophil cells of SHR were higher than that of WKY at each age of 3, 10, 30 days old. Moreover, the number of endocrine cell and the percentage of EC cells amang endocrine cells of the intestine increased gradually after birth in SHR.
