Abstract
The current experiment aimed to identify the possible protective role of rivastigmine (RIVA) in gentamicin (GNT)-induced acute kidney injury (AKI) in rats. RIVA was administered in the presence and absence of GNT. Kidney function markers and serum and renal GNT concentrations were measured. Renal oxidative stress parameters as well as inflammatory and apoptotic biomarkers were evaluated. Renal histopathological assessment and nuclear factor kappa-B (NF-κB) immunohistochemical study were performed. GNT administration increased serum creatinine, urea, and cystatin C concentrations. RIVA ameliorated these changes via mitigating GNT-induced increases of renal oxidative stress, inflammation, and apoptotic parameters. RIVA showed a prompt improvement in the histopathological renal damage and a decrease in NF-κB immunoexpression. In conclusion, RIVA protective effects against GNT-induced AKI are mediated by decreasing GNT concentration in renal tissue and other effects like antioxidant and antiapoptotic effects possibly through its cholinergic anti-inflammatory action.
