摘要: Liver cirrhosis is a critical stage of chronic liver diseases that can produce failure, portal hypertension and hepatocarcinoma. Sustained oxidative stress plays key role in cell damage fibrosis induced during cirrhosis. We evaluated the effect regulation by melatonin on development parenchymal destruction stellate activation experimental Melatonin was administered to rats with thioacetamide (TAA) for 1 or 3 months. injury assessed serological analysis, as well hematoxylin-eosin staining situ apoptosis detection assay sections. Oxidative lipoperoxide reduced glutathione levels, measurement catalase superoxide dismutase activities serum respectively. The cells alpha-smooth muscle actin expression Our results showed TAA extensive tissue enhanced liver. prevented stress-related changes associated toxicity. In conclusion, study prevents TAA-induced rats.
