Promotion of spinal cord recovery by active immunization with MBP. Six rats were immunized subcutaneously with MBP in IFA, and six were injected with PBS in IFA. One week later, the rats were deeply anesthetized, laminectomized, and subjected to spinal cord contusion at T7. At the indicated times, locomotor behavior in an open field was scored. The results are expressed as the mean values for each group (error bars indicate SEM). The differences, tested by repeated ANOVA, were significant (p < 0.05).
