Scalp Electroacupuncture Promotes Angiogenesis after Stroke in Rats by Activation of Wnt/β-Catenin Signal Pathway

Figure 1

Effect of scalp electroacupuncture on cerebral infarction area and blood flow after cerebral ischemia-reperfusion injury. (a) Cerebral tissues from each group were sectioned into 2-mm slices and then processed for triphenyl tetrazolium chloride (TTC) staining. Normal areas of the brain were stained deep red, and the infarct areas remained unstained. (b) Infarct volume was quantified using the Motic Med 6.0 system and is presented as a percentage of the total brain volume vs. the sham group; ^★ vs. the model group. (c) Color-coded perfusion images of cerebral cortex were taken by laser Doppler perfusion imaging system. The density of red color represented the tissue perfusion, which can be used to calculate the areas of ischemic cortex. (d) The relative quantity of the areas of ischemic cortex. vs. the sham group; ^★★★ vs. the model group.
