Popis: OBJECTIVE: To compare the gastric mucosal damage induced by a COX-2 inhibitor, celecoxib, and a conventional NSAID, indomethacin. METHODS: A rat model of NSAID-induced gastric mucosal damage was prepared for indomethacin and celecoxib separately (n = 8). After gastric damage was induced by 100% ethanol, celecoxib was administered by gastric gavage (n = 8). Gastric mucosal concentrations of 6-keto-PGF1α and TXB2 and the lesion index (LI) were measured. Morphological changes of the gastric mucosa were assessed under light and scanning electron microscopy. RESULTS: Indomethacin caused marked gastric damage (LI: 13.38 ± 2.06) and significant reduction of the concentrations of 6-keto-PGF1α and TXB2 (P
