The study of the potential importance of pravastatin in the prevention of the cholestatic liver impairment. Obstructive cholestasis is a clinical syndrome accompanying numerous liver diseases. Early diagnosis and appropriate treatment of obstructive jaundice is very important because untreated condition leads to irreparable changes in the liver. This gives rise to liver fibrosis, which later passes into biliary cirrhosis with all its consequences (portal hypertension, esophageal varices, liver failure). The causal therapy such as surgical removal of the obstruction is quite often impossible. Therefore it is necessary to search for pharmacotherapeutic approaches that can positively modulate the developing disease. In the present thesis, the effect of pravastatin on the liver damage during chronic obstructive cholestasis was investigated in rats. Pravastatin, belonging to a group of widely used inhibitors of HMG-CoA reductase, possesses not only lipid-lowering action but also anti-inflammatory and antioxidant effects, so called pleiotropic effects. The decisive fact for choosing pravastatin as a suitable substance for our study was that pravastatin has already shown positive effects in several patients with cholestasis and its hydrophilic nature does not require metabolism in impaired liver and allows... |
