Cirrhosis is the consequence of chronic liver injury Considering the crucial role of oxidative stress in the progression of liver cirrhosis, we aimed to investigate the ameliorative effect of NTX against oxidative stress in carbon tetrachloride (CCl4)-induced cirrhotic rats. Eighty-four male Wistar rats were randomly assigned into 4 groups (21 rats /group I) receiving CCl4; (II) NTX+CCl4; (III) mineral oil (M) (as the control); (IV) NTX+M. The animals in each group were sacrificed in 3 different time-points 2 weeks, 6 weeks (early cirrhosis) and 8 weeks (advanced cirrhosis). Liver function tests, NO metabolites, GSH level, as well as the activity of antioxidant enzymes including superoxide dismutase (SOD), catalase (CAT), glutathione peroxides (GPX), and hexokinase (HK) were assessed. NTX was able to ameliorate liver injury, revealed by attenuation of ALT activity, which was significantly enhanced due to cirrhosis induction, as well as pathological evaluation. HK was also increased significantly after treatment with CCl4 while NTX moderated this increase. Although CCl4 treatment did not have a significant effect on GSH levels, NTX was able to considerably increase GSH in blood. The activity of CAT and SOD as well as NO levels were all augmented by NTX in CCl4-treated rats. Naltrexone demonstrates antioxidative effects in liver cirrhosis and may confer a protective effect against hepatic cirrhosis through modulation of oxidative stress. [ABSTRACT FROM AUTHOR] |
