Immunofluorescence quantification of myelin basic protein to assess myelin sheath damage after 16 days post MOG induction. A, Myelin sheath marker MBP (red). The myelin damage in the subcortical white matter of spinal cord was alleviated in PCB group at 16 days of MOG induction; B, Caspase 3 activity to asses apoptotic marker in CNS. Significant improvement of cell damage observed at PCB treated groups. For each group values were presented as mean ± SD. One way ANOVA followed by post hoc t-test were used for statistical analysis (significant at p. ≤ 0.05).
