Experimental evidences suggest a role of reactive oxygen species in gentamicin-induced nephropathy in rats. Therefore, we investigated if diallyl disulfide, a garlic-derived compound with antioxidant properties, has a renoprotective effect in this experimental model. Four groups of rats were studied: (1) control, (2) gentamicin treated subcutaneously with gentamicin (70 mg/kg/12 h/4 days), (3) diallyl disulfide treated intragastrically with diallyl disulfide (50 mg/kg/24 h/4 days), and (4) gentamicin + diallyl disulfide treated with gentamicin + diallyl disulfide. Gentamicin induced (a) nephrotoxicity, (b) increase in renal oxidative stress, and (c) decrease in the activity of manganese superoxide dismutase, glutathione peroxidase, and glutathione reductase. Diallyl disulfide ameliorated these changes induced by gentamicin. The mechanism by which diallyl disulfide has a renoprotective effect in gentamicin-induced acute renal failure in rats may be related, at least in part, to the amelioration in the oxidative stress and the preservation in the activity of the antioxidant enzymes in kidney.

D007668 Kidney Body organ that filters blood for the secretion of URINE and that regulates ion concentrations. Kidneys
D007674 Kidney Diseases Pathological processes of the KIDNEY or its component tissues. Disease, Kidney,Diseases, Kidney,Kidney Disease

D001806 Blood Urea Nitrogen The urea concentration of the blood stated in terms of nitrogen content. Serum (plasma) urea nitrogen is approximately 12% higher than blood urea nitrogen concentration because of the greater protein content of red blood cells. Increases in blood or serum urea nitrogen are referred to as azotemia and may have prerenal, renal, or postrenal causes.
