Fig. 3. Infarct size 2 days after reperfusion. (A ) Infarct volume (cubic millimeters, mean ± SD). (B ) Percentage of the contralateral hemisphere (mean ± SD). Infarct volumes were measured from 2,3,5-triphenyltetrazolium chloride (TTC)–stained sections and corrected for the effect of brain edema (see Materials and Methods). *P < 0.01 compared with the vehicle group.
