  • Title: Effects of aspirin on gastric mucosal prostaglandin E2 and F2 alpha content and on gastric mucosal injury in humans receiving fish oil or olive oil.
    Author: Faust TW, Redfern JS, Podolsky I, Lee E, Grundy SM, Feldman M.
    Journal: Gastroenterology; 1990 Mar; 98(3):586-91. PubMed ID: 2298365.
    Abstract:
    Gastric mucosal prostaglandin E2 and F2 alpha content was evaluated in healthy human subjects who received either fish oil or olive oil (control) daily for 3 wk before exposure to aspirin or no aspirin. Two hours after aspirin administration, when mean serum salicylate concentration was approximately 12 mg/dl, gastric mucosal prostaglandin E2 and F2 alpha content was reduced by greater than 95% in the fundus and antrum (p less than 0.001) and there was endoscopic evidence of gastric mucosal damage (erosions, submucosal hemorrhages). Fish oil feeding had no significant effect on mucosal prostaglandin E2 or F2 alpha content or on the damaging effect of aspirin on the stomach, despite the fact that fish oil reduced serum triglyceride concentrations significantly. These studies indicate that the damaging effects of aspirin on the gastric mucosa are not influenced by dietary fish oil.
