Objective. The objective of the present study is to investigate the effect of rosiglitazone, metformin, ezetimibe, and valsartan (alone or in combinations) on paraoxonase (PON) activity and PON-mRNA expression in nonalcoholic fatty liver disease (NAFLD). Methods. 54 Male Sprague-Dawley rats were divided to 9 groups: chow diet group (15 weeks); methionine-choline-deficient diet (MCDD) group (15 weeks); MCDD-treated groups for the last 6 weeks with either metformin (M), rosiglitazone (R), metformin plus rosiglitazone (M+R), ezetimibe (E), valsartan (V), or a combination of R+M+V or of R+M+V+E for a total period of 15 weeks. Results. PON activities in serum and liver were decreased in MCDD rats. PON activity in serum increased significantly in all treatment groups. PON activity in liver was also increased significantly, except only in groups R, E, V, R+M+V, and R+M+V+E. Liver PON3 mRNA expression increased significantly in groups R+M, E, V, R+M+V, and R+M+V+E whereas liver PON2 mRNA expression increased significantly in MCDD, R+M, E, V, R+M+V, and R+M+V+E. Conclusions. PON activities in serum and liver were decreased in NAFLD. Treatment with insulin sensitizers, ezetimibe, and valsartan increased PON activity and reduced oxidative stress both in serum and liver.

To investigate the protective effects and possible mechanism of pomegranate flowers polyphenols (PFP) on liver function of rats with diabetes combining non-alcoholic fat liver diseases, diabetes combining nonalcoholic fat liver disease model rats were established with high calorie feeding and small dose intraperitoneal injection of streptozotocin (STZ). Model rats were randomly divided into: model group, metformin group, pomegranate flowers polyphenols low, medium and high dose group (75, 150 and 300 mg x kg(-1)). After four weeks treatment, the levels of FPG, blood fat profiles and serum insulin, ALT, AST levels, SOD and MDA in the liver and serum separately were analyzed with biochemical methods. Paraoxonase (PON1 and PON3) mRNA and protein expression in liver were checked by RT-PCR and immunohistochemical method. Pathological changes of the liver were observed. FPG, IRI, non-HDL-C and transaminase significantly reduced and HDL-C raised in the each PFP dose group; Furthermore, compared with model group, fat drops in liver cells significantly reduced, antioxidant ability enhanced, PON1 mRNA and protein expression level in liver increased significantly. The protective effects of PFP against diabetes combining non-alcoholic fat liver diseases rats might through the increase liver PON1 mRNA and protein expression further enhanced the body antioxidant capacity and reduced IRI so as to ameliorate the rat hepatic steatosis.
