|Title:||Thymoquinone and curcumin attenuate gentamicin-induced renal oxidative stress, inflammation and apoptosis in rats|
|Abstract:||The present study was aimed to investigate the possible protective effects of thymoquinone (TQ) and curcumin (Cur) on gentamicin (GM)-induced nephrotoxicity in rats. Rats were divided into four groups as follows: group 1 received normal saline and served as normal controls, group 2 received GM only, group 3 concurrently received GM and TQ and group 4 concurrently received GM and Cur. At day 21, rats were sacrificed and samples were collected for assaying serum tumor necrosis factor alpha (TNF-α), urea and creatinine levels, and renal lipid peroxidation, glutathione (GSH) content as well as glutathione peroxidase (GPx) and superoxide dismutase (SOD) activities. In addition, kidneys were collected for histopathological examination and immunohistochemical determination of the antiapoptotic protein, B-cell lymphoma 2 (Bcl-2). The biochemical results showed that GM-induced nephrotoxicity was associated with a significant increase in serum TNF-α, urea and creatinine as well as renal lipid peroxidation. On the other hand, renal GSH content and GPx and SOD activities were significantly declined. Concomitant administration of either TQ or Cur efficiently alleviated the altered biochemical and histopathological features. In conclusion, both TQ and Cur showed more or less similar marked renoprotective effect against GM-induced nephrotoxicity through their antioxidant, anti-inflammatory and anti-apoptotic efficacies.|
