Analysis of MAP2 immunopositive areas in GCL. (a) Typical images of the slices taken at 30 weeks after MCAO. Scale bar indicates 20 μm. (b) Time course changes of MAP2 immunopositive areas after MCAO in GCL. Symbols used are as follows: open square, sham; closed triangle, ipsilateral MCAO; open triangle, contralateral MCAO. Statistical significance was evaluated with two-way ANOVA followed by Tukey-Kramer test at each time point (; ; ; versus sham). (c) Analysis of the effect of IMP on MAP2 immunopositive areas at 30 weeks after MCAO. Vehicle [IMP(−)] or 20 mg/kg/day of IMP for 29 weeks [IMP(+)] from 1 week after the surgical operation was administered. Statistical significance was evaluated with one-way ANOVA followed by Tukey-Kramer test (; versus sham [IMP(−)]; versus ipsilateral MCAO [IMP(−)]; /group).
