title: [THE EFFECT OF ACTH-(4-7)-PGP PEPTIDE ON LIPID PEROXIDATION IN LIVER AND ACTIVITY OF SERUM TRANSAMINASES IN RATS UNDER ACUTE AND CHRONIC IMMOBILIZATION STRESS CONDITIONS].
abstract: The effect of ACTH-(4-7)-PGP (semax) intraperitoneal injection at doses of 5, 50, 150 and 450 μg/kg b.w. on the free-radical oxidation and the activity of serum transaminases in Wistar male rats subjected to acute and chronic immobilization stress has been studied. It was found that the peptide administration in the entire dose range studied produced antioxidant effect in hepatocytes and significantly increased the activity of serum ALT and AST at a dose of 450 μg/kg under chronic stress conditions. On the contrary, prooxidant effects were observed at a drug dose of 150 mg/kg under acute stress conditions, and the direction of changes in the ALT and AST values activity depended on the semax dose. The ALT activity was decreased at doses of 5 and 50 μg/kg, but increased at a dose of 450 μg/kg. The AST activity was already reliably increased at a dose of 5 μg/kg.
