title: Serum paraoxonase 1 status and its association with atherogenic indexes in gentamicin-induced nephrotoxicity in rats treated with coenzyme Q10.
abstract: Coenzyme Q10 is a natural antioxidant and scavenger of free radicals. In the present study, we examined the effect of coenzyme Q10 on paraoxonase 1 (PON1) activity, lipid profile, atherogenic indexes and relationship of PON 1 activity by high-density lipoprotein (HDL) and atherogenic indexes in gentamicin (GM)-induced nephrotoxicity rats. Thirty Sprague-Dawley rats were divided into three groups to receive saline; GM, 100 mg/kg/d; and GM plus coenzyme Q10 by 15 mg/kg i.p daily, respectively. After 12 days, animals were anaesthetized, blood samples were also collected before killing to measure the levels of triglyceride (TG), cholesterol (C), low-density lipoprotein (LDL), very low density lipoprotein (VLDL), HDL, atherogenic indexes and the activities of PON1 of all groups were analyzed. Data were analyzed by non-parametric Mann-Whitney test (using SPSS 13 software). Coenzyme Q10 significantly decreased TG, C, LDL, VLDL, atherogenic index, atherogenic coefficient and cardiac risk ratio. HDL level and PON1 activity were significantly increased when treated with coenzyme Q10. Also, the activity of PON 1 correlated positively with HDL and negatively with atherogenic coefficient, cardiac risk ratio 1 and cardiac risk ratio 2. This study showed that coenzyme Q10 exerts beneficial effects on PON1 activity, lipid profile, atherogenic index and correlation of PON 1 activity with HDL and atherogenic index in GM -induced nephrotoxicity rats.
