Efficacy of N-acetylcysteine on neuroclinical, biochemical, and histopathological parameters in experimental spinal cord trauma: comparison with methylprednisolone
Abstract
N-acetylcysteine (NAC) is an antioxidant agent that has been shown to have beneficial effects when treating various diseases. The aim of this study was to investigate the effects of NAC on spinal cord injury in an experimental rat model. A total of 48 adult male wistar albino rats were divided into six groups. Group C included the control rats, group L included the rats that underwent laminectomy, and group T included the rats in which spinal cord trauma was induced by the weight-drop method after laminectomy. Groups M (the methylprednisolone group), N (the NAC group), and MN (the methylprednisolone + NAC group) were the treatment groups. In the fourth group (group M), 30 mg/kg methylprednisolone (MP) was administered as a bolus intraperitoneally (IP), and a standard MP treatmentat a dose of 5.4 mg/kg was applied for 24 h. In the fifth group (group N), only 300 mg/kg NAC was administered as a bolus IP. In the sixth group (group MN), the standard MP treatment and a single 300 mg/kg dose of NAC were administered as a bolus IP. The motor functions of the rats were evaluated on the 1st, 7th, and 14th days using the inclined plane test defined by Rivlin and Tator and the motor scale defined by Gale et al. Spinal cord samples were ob...Continue Reading
