To investigate characteristics of injury potentials after different degrees of spinal cord injury in rats the present study established models of spinal cord contusion with severe, moderate, and mild degrees of injury. Injury potential was measured in vivo using a direct current voltage amplification system. Results revealed that in the first 4 hours after acute spinal cord injury, initial amplitude of injury potential was greatest after severe injury, followed by moderate and mild injuries. Amplitude of injury potential decreased gradually with injury time, and the recession curve was logarithmic. Under the same degree of injuries, amplitude of rostral injury potential was generally less than caudal injury potential. Results suggested that injury potential reflected injury severity, because large initial amplitude of injury potential during the early injury stage implied severe injury. 展开更多
