Effect of electroacupuncture (EA) preconditioning on neuronal histopathological structure in the ischemic penumbra of rats with focal cerebral ischemia/reperfusion (IR) injury (hematoxylin-eosin staining).

Representative stained images in the ischemic penumbra at 6, 24 and 48 hours post-reperfusion or sham surgery. Shrunken cell bodies and nuclear pyknosis (arrows) were observed in the EA and IR groups, but not in the sham group. The degree of histopathological changes in the IR group was more obvious than that in the EA group. Scale bars: 50 μm (n = 4 rats)
