RT - Journal Article T1 - Effect of Coenzyme Q10 Supplementation on Liver Total Oxidant/Antioxidant Status in Streptozotocin-induced Diabetic Rats JF - HBI_Journals YR - 2019 JO - HBI_Journals VO - 22 IS - 4 UR - http://jams.arakmu.ac.ir/article-1-6045-en.html SP - 28 EP - 39 K1 - Coenzyme Q10 K1 - Diabetes mellitus K1 - Total oxidant status K1 - Total antioxidant capacity K1 - Oxidative stress index AB - Background and Aim Oxidative stress is the main factor in the development and progression of diabetes and its related complications. There is growing evidence that antioxidants supplementation can improve oxidative stress induced in diabetes. The present investigation was conducted to study the effects of Coenzyme Q10 (CoQ10) on the Oxidative Stress Index (OSI) in diabetic rats. Methods and Materials A total of 30 male rats were divided into five groups: saline, sesame oil (as a vehicle), CoQ10-treated (10 mg/kg/day), diabetic (induced with streptozotocin: 55 mg/kg), and CoQ10-treated diabetic (10 mg/kg/d). Then, we measured the Malondialdehyde (MDA), Total Oxidant Status (TOS), and Total Antioxidant Capacity (TAC) levels in the rats’ liver homogenate. Additionally, the OSI was calculated. Ethical Considerations The Research Ethics Committee of Arak University of Medical Sciences approved this study (Code: IR.ARAKMU.REC.1397.119). Results results showed a significant decrease in the level of liver MDA (P=0.022), TOS (P=0.03), and OSI (P=0.028) in the CoQ10-treated diabetic group compared to the diabetic rats. No significant change was observed in the total thiol group (P=0.25) and TAC (P=0.77) level in diabetic rats’ livers treated with CoQ10 compared to diabetic rats.
