magnified endoscopic observations on the healing process of experimental ulcers.
Experimental gastric ulcers in the canine stomach were observed and followed up using a magnifying endoscope. There were differences in the healing processes between antral ulcers and ulcers on the corpus. Antral ulcers were healed linearly by epithelization with a glandular structure, and ulcers on the body were healed by covering with a singly layer of epithelium without pit-formation and the scar resembled a shallow depression. These differences were thought to be caused by differences in blood flow, mucosal regenerability and glandular structure.
