Background and aims: Treatment of acute fulminant liver damage arising as a result of various origins (ischemia-reperfusion injury, toxic shock, an infectious cause or cholestasis) still remains a major clinical problem. We currently do not have available clinically proven, pharmacologically effective and universal compound for the treatment of acute liver injury. The main aim of my research work was, therefore, to test the potential hepatoprotective effect of selected cytoprotective drugs and try to find out or suggest their mechanism of action, which we have examined in the systems for the intracellular gaseous signaling molecules NO and CO, where the key enzymes for their formation are NOS / HO respectively. My PhD study had two main directions: 1) Experimental study of the relationship between HO / CO and NOS / NO systems in the environment of hepatotoxic substances on isolated primary rat hepatocytes and in rat model, 2) Evaluation of ameliorative effect of selected substances in the hepatotoxicity models and to test the relationship of this effect on changes in some parameters of cytotoxicity / cytoprotection, antioxidant parameters, gene expression of mRNA for selected genes and histological changes in the state of cells / tissues / organs. Methods: We measured urea, bilirubin and liver...
