Abstract

Lesions induced by aspirin in the small intestine of the rat were visualized after 4 hours by the intravenous administration of a 5 percent solution of pontamine sky blue, 6 BX dye. Dose-response curves in fasted and fed rats indicated that the fed rat was about eight times more susceptible to aspirin-induced intestinal damage than was the fasted rat, while the fasted rat was about 13 times more susceptible to aspirin-induced gastric damage than was the fed rat.
