Effects of AG extract on the brain infarction in MCAO-induced ischemic rats. After MCAO for 90 min and reperfusion for 24 h, brain tissues were coronary sectioned (2 mm thick) and then stained with TTC. (A) Representative photographs of TTC staining of coronal brain sections. (B) The histogram of brain infarction volumes (n = 6 per a group). (C) The histogram of brain edema (n = 3 per a group). Values are expressed as mean ± SD of each group. **P < 0.01 vs. sham, and ##P < 0.01, and ###P < 0.01 vs. vehicle.
