BACKGROUND

Gentamicin (GEN) is considered as a main aminoglycoside antibiotic medicine. The top therapeutic side effect of GEN is nephrotoxicity. The current research was proposed to determine the protective effect of thymoquinone (TQ) on GEN-induced acute renal failure (ARF).

METHODS

The rats were divided into 6 groups: sham group, control group, GEN-treated group and the TQ-treated groups. At the end of the research period, the serum blood urea nitrogen (BUN) and creatinine (Cr) were measured. The kidneys were then removed for evaluating malondialdehyde (MDA), reduced glutathione (GSH), interleukins IL-6, IL-10, IL-18 and IL-1β, tumor necrosis factor α (TNF-α), superoxide dismutase (SOD) and glutathione peroxidase (GPx) levels.

RESULTS

GEN induced a raise in the levels of serum Cr, BUN and also the levels of MDA, IL-6, IL-18, IL-1β and TNF-α with decease in GSH, SOD, GPx and IL-10 in the kidney (p < 0.05). The data illustrated that the significant elevation in the levels of serum Cr, BUN, MDA, IL-6, IL-18, IL-1β, TNF-α and also the reduction of GSH, SOD, SOD, GPx, IL-10 in the kidney were ameliorated in the TQ-treated groups versus the untreated group, in a dose-dependent manner (p < 0.05).

CONCLUSION

The present investigation proposes that TQ may be ameliorated ARF through modulation of the oxidative stress and inflammatory responses.
