title: [Antioxidant effects of L-arginine in the rat heart in experimental rhabdomyolysis].
abstract: The glycerol administration in a dose of 1 ml of 50% water solution/100 g b. w. was found to cause considerable accumulation of the total heme in the rat blood serum that is accompanied by an increase of TBA-reactive products and protein carbonyl derivates contents and by changes of protein level. Heme entering in the heart tissue is observed in the first hours after glycerol injection. The breaches of heart antioxidant-prooxidant balance are noted in twenty-four hours: TBA-reactive products and protein carbonyl derivates accumulation, heme oxygenase and catalase activation, superoxide dismutase activity lowering and reduction of glutathione content elevation. Pretreatment by L-arginine (0.5 h before glycerol administration) almost did not affect the blood serum changes caused by glycerol injection. However in the rat heart L-arginine administration prevents from TBA-reactive products and protein carbonyl derivates accumulation and the breaches of superoxide dismutase and catalase activities. Besides L-arginine causes the ealier heme oxygenase induction. Possible mechanisms of L-arginine protective action in the rat heart under experimental rhabdomyolysis are discussed.
