Gastric Antral Ulcers Induced by a Combination of Acid, Indomethacin and Ischemia in Rats

[摘要] References(14)Cited-By(8)Gastric antral lesions were produced with hemorrhages by vascular ligation-induced ischemia in the prepyloric regions in rats. Additional treatments with intraluminal acid application and indomethacin markedly aggravated the lesions. Histological examination showed that the incidence of ulcers which penetrated the muscularis mucosae was nearly 100% upon treatment with a combination of acid, indomethacin and ischemia. This model provides a useful tool for studying gastric ulcer etiology.
