Figure 2

Effects of PLex and PF on cerebral infarction induced by ischemia/reperfusion injury. Coronal section of brain after ischemia for 90 min and followed by reperfusion for 24 h. Then staining with TTC, the infarction areas appeared white and noninfarction areas appeared red-purple in color. S1→S6: slices from frontal lobe. (a) Treatment with PLex and PF. (b) Statistic percentage of cerebral infarction area of PLex and PF. Scale bar = 1 cm. * , ** , and ** compared with the control group ( ).
