| Research Abstract |
CHRONOLOGICAL CHANGES OF GASTRIC MUCOSAL NERVES OF MICE AND DENSITY OF MUCOSAL NERVES OF OF HUMAN GASTRIC MUCOSA WITH INTESTINAL METAPLASIA WERE STUDIED BY TRANSMISSION ELECTRON MICROSCOPY. NO REMARKABLE CHANGE OF GASTRIC MUCOSAL NERVES OF OLD MICE WAS OBSERVED REGARDLESS OF MILD MUCOSAL ATROPHY WITHOUT INTESTINAL METAPLASIA. REMARKABLE NERVE DEPLETION WAS FOUND IN HUMAN ATROPHIC GASTRIC MUCOSA WITH INTESTINAL METAPLASIA. FROM THESE OBSERVATIONS, IT WAS SHOWN THAT MUCOSAL NERVES MIGHT PARTICIPATE IN DIFFERENTIATION AND ITS MAINTENANCE OF GASTRIC MUCOSAL EPITHELIUM.
NO DEFINITE PARTICIPATION OF MUCOSAL NERVES IN DIFFERENTIATION AND ITS MAINTENANCE OF COLONIC MUCOSAL EPITHELIUM WAS DEDUCED BY COMPARING MUCOSAL NERVE DENSITY OF HYPERPLSATIC POLYP, ADENOMATOUS POLYP AND COLONIC CANCER.
