Abstract |
Administration of indomethacin (250 mg/kg) to mice was followed by the formation of severe ulcerative and erosive injury to the gastric mucosa, inhibition of DNA synthesis, and development of oxidative stress. Fivefold pretreatment with sedatin (100 microg/kg) decreased the area of indomethacin-induced ulcers and erosions, stimulated DNA synthesis, and reduced the severity of oxidative stress. Non- arginine dermorphin analogue did not stimulate DNA synthesis and had no effect on the degree of oxidative stress. After pretreatment with L-NAME, sedatin did not modulate the synthesis of DNA under conditions of indomethacin-induced injury to the gastric mucosa.
