Gentamicin (GM) is an effective and common antibiotic against severe gram-negative infections. However, its nephrotoxic action has limited the extent of its use. The aim of this study was to investigate the protective effects of hydroxytyrosol (HT) on gentamicin induced nephrotoxicity in mice.MethodsMale mice (n = 27) were randomly assigned to three groups: (1) Sham, (2) GM (100 mg/kg for 7 days) (3) GM + HT (2 mg/kg BW; gastric gavages, for 7 days). 24-h urine samples were collected on day 8 and then animal were anesthetized. The blood and kidney tissue samples were collected.ResultsGentamicin led to increase in plasma BUN and creatinine, fractional excretion of sodium and potassium and decrease in creatinine clearance and urine flow rate. SOD and GSH levels were reduced and MDA was increased in the GM group compared with the sham group. In GM + HT group, plasma BUN and creatinine, fractional excretion of Na, creatinine clearance and urine flow rate were decreased in contrast to GM group. Increase in SOD and GSH activity and decrease in MDA compared to GM group were seen.ConclusionsFindings suggest that HT partly protected the kidneys from gentamicin induced nephrotoxicity and it is partly due to antioxidant effect of HT.
