In this study, we investigated the antioxidant and protective properties of date fruit aqueous extract (DFAE) on trichloroacetic acid (TCA)-induced nephrotoxicity in rat. Oral administration of TCA as drinking water (0.5 and 2 g/L) daily for 2 months caused nephrotoxicity as evident by elevated levels of plasma creatinine, urea, and uric acid. Activity of antioxidant enzymes, catalase (CAT) and glutathione peroxidase (GPx), was decreased, whereas superoxide dismutase (SOD) activity and malondialdehyde (MDA) level wereincreased along with histopathological injuries. The oral administration of DFAE (4 mL/kg/day) to TCA-treated groups proved some significant correction by increasing the antioxidant activity of the CAT and GPx enzymes and normalizing the SOD activity and the MDA level (p < 0.05). It also protected kidney's histology and normalized the functions of this organ. It could be concluded that DFAE has a protective role against TCA-induced oxidative stress in rat, thereby protecting the renal tissue from TCA-induced damage.
