Latency time by PAT in the vehicle-sham, vehicle-fIRI, 1 mg/kg aucubin-sham, 1 mg/kg aucubin-fIRI, 5 mg/kg aucubin-sham, 5 mg/kg aucubin-fIRI, 10 mg/kg aucubin-sham, and 10 mg/kg aucubin-fIRI groups 1 day before and 4 days after fIRI. In the vehicle-fIRI, 1 and 5 mg/kg aucubin-fIRI groups, the latency times are significantly shortened when compared with the vehicle-sham group. On the other hand, in the 10 mg/kg aucubin-fIRI group, the latency time is similar to that evaluated in the sham-vehicle group. Values are expressed in mean ± SEM (n = 7, respectively; * p < 0.05 vs. each sham group, # p < 0.05 vs. vehicle-fIRI group).
