Abstract: The potential protective effects of taurine and quercetin against gentamycin (GM)/diclofenac (DC) combined nephrotoxicity were investigated in rats. The results showed that administration of DC alone at an oral dose of 5 mg/kg b.wt/day for 28 days had no significant effect on the measured parameters, except for marked increase in urinary uronic acid excretion. Administration of GM alone at a dose of 100 mg/kg b.wt/day i.p. for 8 days resulted in obvious nephrotoxicity. Combined GM-DC treatment led to the most pronounced nephrotoxicity, as indicated by greater elevations in serum urea, creatinine and urinary N-acetyl-β-D-glucosaminidase (NAG), together with severe depression of renal cortical Na⁺, K⁺- ATPase, compared to GM-treated group. Moreover, only combined treatment resulted in significant decrease in urinary potassium and renal cortical glutathione peroxidase (GSHPx), together with an increase in renal cortical lipid peroxidation products (LPOs). Co-administration of taurine or quercetin normalized creatinine clearance and ameliorated the elevations in urinary proteins, uronic acids, NAG and renal cortical LPOs in GM/DC treated rats. The study justifies the use of taurine and quercetin as renoprotective agents against the nephrotoxicity caused by GM/DC therapy.
