Abstract

The present study investigated the effects of co-administration of aspirin, metformin, atorvastatin and captopril on serum lipid profile and oxidative stress in the heart and kidney of streptozotocin-induced diabetic rats. In this study, rats were randomly divided into the following eleven groups: control (Cont.), and diabetic (D), as well as 9 groups that were treated with metformin (M, 300 mg/kg) or aspirin (ASA, 120 mg/kg) alone or in different combinations with captopril (C, 50 mg/kg), or atorvastatin (AT, 40 mg/kg), as follows: (D + M), (D + ASA), (D + M + ASA), (D + M + C), (D + M + AT), (D + M + C + ASA), (D + M + C + AT), (D + M + AT + ASA), and (D + M + C + AT + ASA). The rats in treatment groups daily received drugs by gavage for six weeks. Finally, serum lipid profile and levels of oxidative markers in the heart and kidney tissues were evaluated.In diabetic rats, blood levels of glucose, cholesterol, TG (triglyceride), LDL (low-density lipoprotein), MDA (malondialdehyde) and AIP (atherogenic index of plasma) significantly increased but those of HDL (high-density lipoprotein) and total thiol as well as SOD (superoxide dismutase) and CAT (catalase) activities significantly decreased. Treatment with different combinations of C, ASA, AT and M significantly ameliorated these parameters. This study showed that co-administration of ASA, M, C and AT, could improve glucose and lipid metabolism and oxidative stress markers in the kidneys and heart tissues of diabetic rats more markedly than the administration of these drugs alone.
