Total number of oligodendrocytes in the corpus callosum (CC). (a)
(A-F), Representative images of haematoxylin-stained corpus callosum
(CC) in each group. a(A), sham-std; a(B), sham-3 h; a(C), sham-full;
a(D), BCAS-std; a(E), BCAS-3 h; a(F), BCAS-full. Scale bar
represents 25 µm. (b) Histogram showing total number of
oligodendrocytes in the entire CC. BCAS-3 h showed increased number
of oligodendrocytes in the entire CC compared with BCAS-std and
BCAS-full (both **P < 0.01). BCAS-full showed
increased number of oligodendrocytes compared with BCAS-std
(*P < 0.05).
