Effect of KRG on neurological deficits. Neurological deficits were evaluated in the saline and KRG group immediately before and 1, 3, and 7 days after MCAO/R using (A) the modified neurological severity scores (mNSS) graded on a scale of 0 to 18 (0, no neurologic deficit; 18, maximal deficit) and (B) the corner test. The values are reported as the means ± SEM.; n=8–12. *p<0.05, **p<0.01 vs. saline group. KRG, Korean red ginseng; MCAO/R, middle cerebral artery occlusion/reperfusion.
