Figure 4: Effect of CEGI on the infarct volume of MCAO rats detected by TTC staining. (A) Cerebral infarction in the representative coronal brain slices. (B) Quantitative analysis of infarct size in brain tissues. The percentage of infarction in the MCAO + 4 mL/kg/d CEGI group was significantly decreased compared with that in the MCAO group on days 7 and 14 post-MCAO (P < 0.05). Data are presented as the mean ± SEM (n = 6 per group at each time point). *P < 0.05, vs. MCAO group (Kruskal-Wallis one-way analysis of variance followed by Dunn's post hoc test). CEGI: Cattle encephalon glycoside and ignotin; MCAO: middle cerebral artery occlusion; TTC: 2,3,5-triphenyltetrazolium chloride.
