Fig. 1From: Electroacupuncture at different frequencies (5Hz and 25Hz) ameliorates cerebral ischemia-reperfusion injury in rats: possible involvement of p38 MAPK-mediated anti-apoptotic signaling pathwaysFocal cerebral infarct areas (S1-S6) in the experimental groups after 30 min of ischemia followed by 7 days of reperfusion. 2,3,5-Triphenyltetrazolium chloride staining shows noninfarct (red) and infarct (white) regions.
