Özet

Benzo(a)pyrene (BaP) is a polycyclic hydrocarbon with carcinogenic and DNA damaging properties. Curcumin, primary yellow pigment in turmeric, has a wide range of biological, pharmacological properties in addition to being a powerful antioxidant. The aim of this study was to investigate protective effects of curcumin against benzo(a)pyrene damage in rat kidney. Thirty-six male Wistar albino rats were divided into six groups (n = 6) as: control, corn oil, Dimethyl sulfoxide (DMSO), BaP (10 mg/kg/day), Curcumin (100 mg/kg/day), Curcumin+BaP (100 mg/kg/day+10 mg/kg/day). Agents were daily and orally administered for six weeks. Kidney tissues were removed and examined ultrastructurally. Glomerular and tubular structures in control, corn oil, and DMSO groups demonstrated normal features. Glomerular capillary dilation, thickening, and folding of basement membrane and disruption of organelle contents were distinguished in BaP group. Deletion of podocyte cell and pedicels also sponge-like appearance of glomerular surface were remarkable in this group. Tissue components were protected in curcumin treated group. Proximal tubules and glomerular basement membrane exhibited normal features in Curcumin+BaP group. The abnormalities that accompanied BaP administration clearly revealed the detrimental effects of this agent. Therefore, this study provided substantial evidence that curcumin protects against benzo(a)pyrene nephrotoxicity.
