Background and Aim: The aim of this study was to compare the effects of hydro-alcoholic extract of Curcuma longa (C.L E) and Nigella sativa (N.S E) with Vitamin C on renal-oxidative damage in rats.
Methods: 40 male Wistar rats were randomly divided into five groups (n=8) as follows: A Control group with plain drinking water and intervention groups including positive control groups with Vitamin C (100 mg/kg), the N.S E (200 mg/kg) group, the C.L E (1000 mg/kg) group and N.S E and C.L E group (receiving 200 and 1000 mg/kg, respectively), all dissolved in drinking water and fed during the 35 days of the experiment. At the end of this period, the renal tissues were removed and oxidation-reduction markers were investigated.
Results: N.S E (P <0.001), C.L E and vitamin C (P <0.01) decreased serum creatinine and BUN levels in comparison to the control group. Not only were the levels of total thiol higher in the Vitamin C (P <0.001), N.S E, C.L E (P <0.05) and N.S E and C.L E (P <0.01) groups compared to the control group, but also the superoxide dismutase (SOD) activity was more elevated in Vitamin C and N.S E and C.L E groups (P <0.01). Malondialdehyde (MDA) concentrations in the N.S E and C.L E, N.S E (P <0.001) and Vitamin C (P <0.05) groups were lower than those in the control group.
Conclusion: In the current study, it was found that N.S E and C.L E have a significant effect on the improvement of renal oxidative stress; which is comparable to Vitamin C. A higher synergistic effect of N.S E and C.L E suggested that they are more effective combined than when used separately.
