Ischemic pathological changes in rats 72 hours after cerebral ischemia (hematoxylin-eosin staining, × 1,000; scale bars: 20 μm).

(A) Sham surgery group: normal neurons, blood vessels, gliocytes, and nerve fibers. (B) Model group: neuronal damage, angioedema, and disor-dered nerve fibers. (C) Wind-dispelling drug group: neuronal loss, gliocyte proliferation, and vascular edema. (D) Deficiency-nourishing drug group: decreased neuronal loss and reduced vascular edema. (E) Houshiheisan group: reduced necrosis. Arrows indicate neurons.
