In an attempt to elucidate the role of granulation vessels in the healing of gastric ulcer, healing and angiogenesis in granulation tissue of acetic acid ulcers were studied in rats. In addition, the effects of prednisolone and synthetic human epidermal growth factor (EGF) on angiogenesis and ulcer healing were investigated. The newly formed granulation vessels in the ulcer base were measured by means of a carmine dye infusion method. Prednisolone, administered subcutaneously at 40 mg/kg/day, significantly decreased angiogenesis in the ulcer base on the 10th day after ulcer production, and on the 30th day ulcer healing was found to be significantly delayed. In contrast, angiogenesis was significantly increased, and ulcer healing was enhanced by intragastric administration of 100 micrograms/kg/day of EGF. With combined administration of prednisolone and EGF, angiogenesis was significantly increased compared to that observed with prednisolone treatment alone. The authors conclude that suppression of angiogenesis by prednisolone is a delaying factor in gastric ulcer healing and that exogenous EGF promotes ulcer healing, partly through restoration of angiogenesis.
