[EFFECT OF ACETYLCYSTEINE, CORVITIN AND THEIR COMBINATION ON THE FUNCTIONAL STATE OF LIVER IN RATS WITH PARACETAMOL INDUCED TOXIC HEPATITIS].

Abstract

Nowadays drug-induced hepatotoxicity is urgent problem worldwide. Currently more than 1000 drugs are hepatotoxic and most often are the reason of acute fulminant hepatitis and hepatocellular failure, the states requiring liver transplantation. The paracetamol induced liver toxicity is related with accumulation of its toxic metabolite N-acetyl-p-benzoquinone imine (NAPQI), which is the free radical and enhances peroxidation of lipids, disturbs the energy status and causes death of hepatocytes. During our research we investigated and assessed the efficacy of acetylcysteine, corvitin and their combination in rat model of paracetamol induced acute toxic hepatitis. The study was performed on mature white male Wistar rates with body mass 150-180 g. 50 rats were randomly divided into 5 groups (10 rats in each group). To get the model of acute toxic hepatitis single intraperitoneal injection of paracetamol solution was used (750 mg/kg). Toxic hepatitis was treated with intrapertoneal administration of 40mg/kg acetylcysteine or 100mg/kg corvitin, as well as with combination of these drugs. Monotherapy with acetylcysteine and corvitin of paracetamol induced toxic hepatitis improved the liver function, decreased relative mass of the liver and animal mortality. The treatment of toxic hepatitis was most effective in the case of simultaneous administration of acetylcysteine and corvitin. The normal value of laboratory tests (ALT, ACT, alkaline phosphatase, total and unconjugated bilirubin) was reached and mortality was not more observed. On the bases of obtained data was concluded that acetylcysteine and corvitin have almost equal hepatoprotective activity. The combination of two drugs actually improves the liver function. The most pronounced hepatoprotective effect may be due to synergic action of acetylcysteine and corvitin and such regime can be recommended for correction of liver function.
