This study aimed to evaluate the effects of dantrolene (DAN) and mesenchymal stem cells (MSCs) in acute spinal cord injury (SCI). Sixty Wistar rats were divided into groups MSCs, MSCs + DAN, DAN, trauma and placebo (TP) and no trauma and placebo (STP). Laminectomy was performed at T12 level in all animals, followed by a weight-drop model of SCI, except for the STP group. An hour later, the MSCs + DAN and DAN groups received 10mg/kg of DAN. After seven days, the MSCs and MSCs + DAN groups received 1x106 cells intravenously. Behavioral tests were performed to assess functional recovery for 28 days. Traumatized animals showed paraplegia. There was a significant improvement in groups MSCs, DAN and MSCs + DAN compared to TP (p<0.05). It was concluded that DAN and MSCs for the treatment of SCI in rats have neuroprotection effect and promote functional neurological improvement. |
