Abstract

Aim: To examine the effect of eradication of Helicobacter pylori prior to usage of NSAIDs, by investigating gastric inflammatory activity, myeloperoxidase (MPO) activity, prostaglandin (PG) E2 synthesis in H pylori-infected, and H pylori-eradicated gerbils followed by administration of indomethacin and rofecoxib. Methods: Six-week-old male gerbils were orally inoculated with H pylori. Seven weeks later, anti-H pylori triple therapy and vehicle were given to gerbils respectively and followed by oral indomethacin (2 mg/kg·d) or rofecoxib (10 mg/kg·d) for 2 wk. We examined the area of lesions, gastric inflammatory activity, PGE2 synthesis and MPO activity in the stomach. Results: In indomethacin and rofecoxib-treated gerbils, the following results were obtained in H pylori-infected group vs H pylori-eradicated group respectively: hyperplasia area of the stomach (mm2): 82.4±9.2 vs 13.9±3.5 (P2): 14.4±4.9 vs 0.86±0.5 (P2O2/min/g tissue): 104.7±9.2 vs 9.0±2.3 (P2 synthesis (pg/mg wet weight/min): 299.2±81.5 vs 102.8±26.2 (P
