Abstract:
Objectives:Traumatic spinal cord injury (SCI) is a significant clinical problem with numerous secondary complications and perpetual deficits. No potent treatment is currently available to fully repair motor and other neurological functions. We studied the effects of dantrolene (DNT) at different time points, on the motor-evoked potentials (MEPs) and the apoptosis response in spinal cord injury. Methods:The study was conducted on a total of 38 rabbits divided into five main groups.These were group 1 (sham): only laminectomy (n = 6), group 2 (SCI): laminectomy and traumatic SCI (n = 8), group 3 (DNT 0h): just after the SCI, DNT 10 mg/kg I.P. (n = 8), group 4 (DNT 1h): 1 h after the SCI, DNT 10 mg/kg I.P. (n = 8), and group 5 (DNT 4h): 4 h after the SCI, DNT 10 mg/kg I.P. (n = 8). Results: DNT, which was administered as the treatment, had a therapeutic effect on the motor function. This effect was observed by recording neural transmission obtained via the Tarlov test and a transcranial magnetic stimulator by using the values of the MEPs. A significant decrease was histopathologically observed in the apoptotic cell count. Discussion: The electrophysiological efficacy of our model of trauma as SCI has been complemented with the significant differences between the control group and the SCI group. This creates a need for electrophysiological studies to be conducted in the future because effects, even at a minimum level, may play an important role in finding an applicable medicine for SCI.
