Fig. 6. The number of intact neurons in the ischemic penumbra and the ischemic core 7 days after ischemia. Intact neurons were counted in an area of 0.22 mm²on hematoxylin and eosin stained sections at ×250 magnification using a light microscope. The histologist was blinded to the treatment. The primary somatosensory cortex was defined as the ischemic penumbra and the secondary somatosensory cortex as the ischemic core. Values are mean ± SD. *P < 0.01, #P < 0.05 versus  the vehicle group.
