Abstract

We investigated the effect of Vitamin C (Vit C) on the changes of activity of the enzymes of NO-synthase system, nitric oxide content, lipoperoxidation processes, activity of SOD and catalase in gastric mucosa (GM), and concentrations of L-arginine, Vit C and Vit E in the blood of rats under conditions of experimental ulcer of the stomach caused by adrenaline injection. Vit C displayed a pronounced antioxidant action, reduced the degree of destructive affections, diminished the activity of iNOS and lipoperoxidation processes, decreased the NO content and SOD activity. Furthermore, the concentration of L-arginine and Vit C in the blood was in­creased. Combined action of Vit C with L-arginine reduced the degree of GM lesions, activity of eNOS and the content of NO in GM whereas the concentration of L-arginine in blood was increased. Under conditions of Vit C action and iNOS and COX-2 blockage, the activity of NO-synthases and lipoperoxidation processes were slightly decreased, indicating on dominant action of Vit C.

Keywords: ascorbic acid, nitric oxide, NO-synthases, COX-2, L-arginine, lipoperoxidation, experimental ulcer
