Objective: The objective of this study is to examine the effects of the alpha-tocopherol on rats with spinal cord injury (SCI). Setting: Research Center, Sultan Bin Abdulaziz Humanitarian City, Riyadh, Kingdom of Saudi Arabia. Method: Female Sprague-Dawley rats weighing 180-220 g were anesthetized with chloral hydrate (450 mg kg À1 body weight) by intraperitoneal injection and laminectomy was performed at the T 7-8 level leaving the dura intact. A compression plate (2.2 Â 5.0 mm) was loaded with a weight of 35 g placed on the exposed cord for 5 min to create SCI. The subjects were divided into three groups of eight rats each. Group 1 served as control (SCI þ saline); whereas groups 2 and 3 served as test groups, alpha-tocopherol was given orally in doses of 1000 mg kg À1 body weight for group 2 and 2000 mg kg À1body weight for group 3, respectively. Daily activities were recorded in the activity cage for 14 days post-operatively. Results: At day 1 (baseline, 24 h after the surgery), there was no significant difference between mean motor scores of all groups. After day 1, the three groups showed continuous improvement in motor score; such improvement was maintained throughout the duration of the study with different levels for each group. By the end of the study (day 14), groups 2 and 3 showed statistically significant improvement in the mean motor score compared with group 1 (Po0.05). However, no significant difference was observed between test groups 2 and 3 by the end of the study. Conclusion:The results suggest that the administration of alpha-tocopherol may have reparative effects for SCI because of its antioxidant effect.

These results suggest that 2 weeks of treadmill locomotor training and swimming training may have positive effects on functional recovery after partial SCI.
