Protective role of citronellol on antioxidant enzymes and oxidative damage induced by gentamicin in experimental nephrotoxic rats.

BACKGROUND

Gentamicin leads to nephrotoxicity with increasing oxidative stress. In the present research the role of citronellol on oxidative damage induced by gentamicin in nephrotoxic rats was evaluated.

METHODS AND

RESULTS

Forty-twomale Wistar rats were randomly divided into seven equal groups; healthy control, gentamicin, DMSO, citronellol 50, citronellol 100, citronellol 200 and vitamin E. The animals were anesthetized after 12 days of treatment. Kidney and serum samples were received for biochemical, histological changes, and gene expression assessments. The levels of serum glutathione (GSH), serum and kidney glutathione peroxidase (GPX) and the expression of GPX gene against gentamicin group were increased in citronellol treatment groups. The levels of serum and kidney malondialdehyde (MDA), urine protein, serum creatinine and the gene expression of inflammatory factors including tumor necrosis factor-alpha (TNF-α) and Interleukin 6 (IL-6) against gentamicin group were decreased in these groups. Moreover, recuperation in histological alterations was shown in three groups receiving citronellol compared to the gentamicin group.

CONCLUSIONS

Citronellol with its antioxidant and anti-inflammatory properties can decrease kidney damage caused by nephrotoxicity induced by gentamicin.
