Amikacin is a commonly used antibacterial drug that can cause significant nephrotoxic effects in both humans and experimental animals. It has been reported that one mechanism of the toxic effects of aminoglycoside antibiotics are the result of oxidative reactions. The aim of this study is to examine the effects of N-acetylcysteine, a thiol-containing antioxidant, on renal function (serum creatinine) and morphology (renal tubular damage) in mice subjected to amikacin-induced nephrotoxicity. A total of 32 mice were equally divided into four groups that were injected with either saline, amikacin (1.2 g/kg intraperitoneally), N-acetylcysteine (150mg/kg intraperitoneally for three days) plus amikacin (1.2 g/kg intraperitoneally on the third day as a single dose), or N-acetylcysteine (150mg/kg intraperitoneally). Amikacin administration led to granulovacuolar tubular degeneration in light microscopic examination and myeloid bodies. mitochondrial electron-dense material deposition, and mitochondrial swelling in the proximal tubule epithelium in the electron microscopic evaluation. N-acetylcysteine administration before amikacin injection caused significant decreases in myeloid body and mitochondrial swelling and granulovacuolar tubular degeneration formation. Serum creatinine levels did not change as a result of any treatment. The results show that N-acetylcysteine has a protective effect on nephrotoxicity induced by amikacin. Higher doses of amikacin should be tried to observe biochemical effects.
