title: Mechanisms for the effect of arginine-containing dermorphin analogue on proliferative processes in the gastric mucosa of albino rats.
abstract: Treatment with synthetic arginine-containing dermorphin analogue sedatin (100 mg/kg, 5 intraperitoneal injections) stimulated DNA synthesis in the gastric mucosa and decreased spontaneous and induced chemiluminescence in homogenates of the stomach from albino rats. Non-arginine sedatin analogue in the same dose had little effect on DNA synthesis and free radical oxidation. Fivefold treatment with NO synthase inhibitor L-NAME (9.3 x 10(-5) mol/kg) suppressed DNA synthesis in the gastric mucosa. Sedatin did not modulate DNA synthesis against the background of L-NAME administration.
