Abstract
Endocrine cells in the cardiac and fundic regions of the Korean hedgehog were studied ultrastructurally. Five types of endocrine cells classified as EC, ECL, $D_1$. G and A-like cells were identified in these regions. EC cells contained pleomorphic granules, 170~500nm in diameter, with high electron density and highly dense bodies in a dense matrix. ECL cells were characterized by the presence of round or oval granules, 220~450nm in diameter, with high electron density. Some granules of ECL cells showed a small amounts of contents or empty. $D_1$ cells contained round and relatively small granules, 140~400nm in diameter, with low to moderate electron density. G cells were characterized by the presence of round or oval granules, 200~400nm in diameter, with moderate electron density. Some granules of these cells showed a narrow halo between the limiting membrane and the granular matrix. A-like cells contained round granules, 170~260nm in diameter, With high electron density. The granules of these cells showed homogeneous matrix surrounded by the tight membrane.
Key Words: endocrine cell, Korean hedgehog, fundic and cardiac regions, gastrointestinal tract
