Light microscopic investigation of quercetin's effects on kidney injury induced by doxorubicin in rats

Aim: The anthracycline antitumor drug doxorubicine causes severe nephrotoxicity in a variety of experimental animals and may be nephrotoxic to humans. This effect may be the consequence of oxidative stress. The aim of present study was to determine by light microscopy the doxorubicin-induced structural/histological changes and protective effects of co-administration of quercetin in doxorubisin induced kidney injury.Material and Methots: Forty adult, male Wistar albino rats were used and were divided into four groups: I, control (n=10); II, doxorubicin (n=10); III, doxorubicin + quercetin , (n=10); IV, quercetin (n=10). In the doxorubicin group; the animals were treated with single dose 20mg/kg/i.p doxorubicin. After administration of the drugs, the rats were decapitated and their kidneys were removed and fixed in 10% neutral-buffered formalin. Tissue samples were stained with H&E (Hematoxylin-Eosin) and histological examined with light microscopy.Findings: It was found that on the kidney of rats which was given doxorubicin, renal tubular dilation, tubular vakuoler changes, glomerular vakuolizasyon, a decrease in space bowman, bowman capsule thickening and interstitial infiltration on light microscope.Results: As a result of this study it was found that quercetine may decrease kidney damage, which was occured by doxorubicin.Key Words: Doxorubicin, Quercetin, light microscope, kidney injury, rat.
