Abstract
Changes in gastric mucosal blood flow during the healing process of gastric artificialulcer caused by endoscopic mucosal resection were investigated by laser doppler flowmeter. In 191esions (19 cases), we examined mucasal bland flaw at the edge of artificialulcer and surrounding mucosa. In the course of ulcer healing, mucosal blood flow of ulcermargins increased significantly at the scarring stage compared with active stage(p<0.05).Put the surrounding mucosal blood flow was not significantly changed. In the early healedgroup, mucosal blood flow at the ulcer margins and surrounding mucosa is higher than inthose of the protracted group at the healing stage(p<0.05). This results is suggested thatthe speed of ulcer healing is depend on the supply of mucosal blood flow in the healingprocess of acute gastric ulcer.
