To evaluate the effect of Bangpungdangkwi-eum extracts on reperfusion following the middle cerebral artery occulsion in Sprague Dawley rats, the neuron protection effect were investigated through examining the size of cerebral infarction, cerebral edema, and the morphologic change of neuron. The results were obtained as follows; 1. The size of cerabral infarction in sample group is significantly decreased compared with that in control group. Sample group has approximately 17% cerebral infarction parts induced by ischemia in cerebrum while control group has approximately 22%. 2. The volume of cerebral edema in sample group is significantly decreased compared with that in control group. The volumn in sample group is increased by approximately 4.4% compared with that in normal group while that in control group is increased by approximately 7.7%. 3. The optical microscopic examination reveals that the damage of neurons in the ischemic parts and CA1 and CA3 region of hippocampus in the same side of the ischemic parts was the most high and the damage in sample group is decreased compared with that in control group.
