Objective : The purpose of this study was to investigate the neuroprotective effect of Jukryuk on 4-vessel occlusion(4-VO) and middle cerebral artery (MCA) ischemia. Method : After administration of Jukryuk, we compared the Jukryuk-treated group, the control, and the sham groups, in view of several points as follows 1) We evaluated the damage characterized by coagulative cell change of pyramidal neurons and pronounced gliosis in each group 2) We counted the number of normal pyramidal shapes after ischemia in each group 3) Immunohistochemistry (cyclooxygenase-2) 4) In focal ischemic injury model, we measured the volume of ischemic area Results : In this experiment, the effect of Jukryuk was determined to be protecting neuron cell shape, reducing the number of neuron cells damaged by ischemia and the volume of the ischemic area. In immunohistochemistry, Jukryuk reduced cyclooxygenase-2 expression Conclusions : According to this study, Jukryuk can protect neuron cells from injury by cerebrovascular ischemia.
