Objective: The main objective of this study is to investigate the antioxidant and nephroprotective efficacy of moringa oleifera seed extract (MOSE) against cisplatin which induced acute renal injury.
Methods: Forty male Wister rats were equally segregated into 4 groups (10 rats per group): group I (0.5 ml of sterile saline orally), group II (200 mg MOSE/kg b. wt orally for 10 consecutive days), group III (7.5 mg cisplatin/kg b. wt/intraperitonially as a single dose on the 5th day of the experiment) and group IV (200 mg moringa oleifera seed extract (MOSE)/kg orally for 10 d followed by 7.5 mg cisplatin/kg body weight/intraperitonially once as a single dose on the 5th day of the experiment. Serum biochemical analysis of renal biomarkers (urea, uric acid, and creatinine), oxidative stress markers (malondialdehyde [MDA]), a crucial antioxidant enzyme (catalase) and the expression of renal activity interleukin (IL)-6, (IL)-10 and Tumor necrotic factor (TNF-α) mRNA were determined. Histopathological examination of renal tissue was done.
Results: Cisplatin induced renal damage, increased renal biomarkers (urea, creatinine and uric acid)(375.87±1.65, 5.238±0.25, 4.47±0.25). Tissue concentrations of malondialdehyde, IL-6 and TNF-α. (387.56±0.97, 2.188±0.20, 3.06±0.27)compared to control group(140.58±1.25,0.938±0.017, 1.24±0.17), (163.99±1.34, 1.008±0.05, 0.982±0.026) Moreover, cisplatin induced significantly down-regulation of anti-inflammatory (IL-10) and catalase (0.780±0.47, 1.62±0.06) compared to control one (1.010±0.02, 3.12±0.11),. The histopathological examination showed renal tissue damage and degeneration of tubules in the cortical portion in cisplatin group. However, interestingly concurrent adminsteration of the MOSE with cisplatin can alleviated the renal damage, oxidative stress and renal toxicity caused by cisplatin.
Conclusion: These results suggest that the antioxidant and the anti-inflammatory effects of MOSE alleviate the cisplatin-induced nephrotoxicity.
