Aims: Bladder toxicity is one of the major toxicity effects associated with cancer chemotherapeutic treatments with Cyclophosphamide (CP) and Buthionine-SR-Sulfoximine (BSO). In the current study, we utilized a Swiss albino mouse model to investigate the effects of Nigella sativa seeds (NSE) pre-treatment on the urotoxicity produced by acute concentrations of CP and Buthionine-SRSulfoximine (BSO).
Methods: To evaluate the toxicity modulation, we carried out several measurements such as Lipid Peroxidation (LPO), Peroxide Hydrogen production (H2O2), and antioxidants in the urinary bladder of the mice. Results: The findings revealed that NSE pre-treatment induced a protective effect in terms of LPO, H2O2 and enzymatic antioxidant activities. The levels of Glutathione S-Transferase (GST), Glutathione Reductase (GR), Glutathione Peroxidase (GP), and Catalase (CAT) in mice exposed to CP were significantly lower than in controls. The data obtained also show a decrease in Glutathione (GSH) levels and an increase in LPO activity in the CP-treated mice group. BSO treatment has shown an additive toxic impact in CP-treated mice. Our findings emphasize NSE's ability to restore enzymatic activity and hence provide protection against CP and BSO.
Conclusion: From the outcome of our investigation, it is possible to conclude that NSE has a powerful preventive effect against CP and BSO urotoxcicity. As a pre-treatment, NSE restores GSH which might contribute to the CP-induced apoptosis reversal and the free radical-mediated LPO.
