Fig. 9From: Electroacupuncture at different frequencies (5Hz and 25Hz) ameliorates cerebral ischemia-reperfusion injury in rats: possible involvement of p38 MAPK-mediated anti-apoptotic signaling pathwaysExpression of p-CREB/DAPI doubled-labeled cells in the ischemic cortical penumbra. Representative photographs show p-CREB-immunoreactive cells and DAPI-stained nuclei. The merged image shows p-CREB immunoreactivity and DAPI-stained nuclei in the ischemic cortical penumbra 7 days after reperfusion. N, negative control. The white arrows indicate intense p-CREB (red) immunoreactivity and p-CREB/DAPI staining (merged image). Scale bar = 5 μmBack to article page
