The influence of hepatoprotector phospholipid nature Essentiale and Essenciale combination with succinic acid on the metabolism of liver injury caused by Paracetamol in rats has been investigated. As a result of therapy was decreased Paracetamol hepatotoxicity — in the blood reduced the aminotransferases, alkaline phosphatase activity, bilirubin content, in liver homogenates decreased production of diene conjugates, Schiff bases and malondialdehyde. Essentiale improved the oxidative phosphorylation conjugacy without influence on liver mitochondria respiratory activity kinetic parameters. Combined application of Essentiale and succinic acid normalized the liver mitochondria respiratory function.
