Sodium salicylate (SA) has been reported to inhibit the formation of gastric ulcerations induced by aspirin, indomethacin, and absolute ethanol. In this study, SA dose-dependently inhibited gastric ulcers induced by three hours of cold-restraint stress (CRS); SA-induced cytoprotection was prevented by both acetylsalicylic acid (aspirin) and indomethacin pretreatment. Neurotensin (NT), which has previously been demonstrated to prevent the development of CRS-induced gastric ulcerations after intracisternal administration, was found to be ineffective in animals pre-treated with aspirin, and with indomethacin, as previously described. These data suggest that in the CRS model both NT- and SA-induced gastric cytoprotection require a functionally intact gastrointestinal prostaglandin synthetic pathway.
