[The effect of agmatine on L-arginine metabolism in erythrocytes under streptozotocin-induced diabetes in rats].

The effects of agmatine on oxidative and nonoxidative metabolic pathways of L-arginine were investigated both in plasma and erythrocytes under experimental diabetes mellitus. It was indicated, that agmatine prevents the development of oxidative-nitrosative stress in diabetic rats. After treatment of animals by agmatine NO-synthase methabolic pathway of L-arginine is depressed whereas arginase one increases in erythrocytes of rats with experimental diabetes mellitus.
