Figure 3: Effect of CEGI on the cerebral infarction induced by MCAO detected by MRI. (A) Differences in residual infarct volume revealed by MRI T2-weighted images on day 7 and 14 post-MCAO. (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 were 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.
