Abstract

Background

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.

Methods

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 obtained on the 14th day. The samples were evaluated using pathological and biochemical analysis.

Results

In the neuroclinical assessment, no differences were observed between groups T and M in terms of motor improvement. However, statistically significant differences were observed between group T and groups N and MN (p < 0.001, p = 0.01, respectively). Statistically significant differences were also seen between group M and groups N and MN on the 1st and 7th days (p < 0.017, p < 0.01, respectively). Additionally, when groups N and MN were compared with groups T and M,the pathological and biochemical analyses were found to be statistically different (p < 0.05, p < 0.001, respectively).

Conclusion

It was concluded that NAC treatment and the combined NAC + MP treatment may be more useful for healing in rats with experimental spinal cord injury in terms of neuroclinical, pathological, and biochemical results than MP-only therapy.
