Objective : The purpose of this study was to investigate the effect of Jukryuk and Saengkang-juices on cerebral vascular ischemia (CVI) of the middle cerebral artery (MCA). Method : By admiuistration Jukryuk and Saengkang-juices, we compared treated groups with untreated groups, in view of five points as follows: 1) cerebral damage; 2) damaged area of ischemia; 3) cerebral edema; 4) the number of neuronal cells adjacent to the areas damaged by ischemia; and 5) the number of neuronal cells adjacent to the areas damaged by ischemia Results : In this experiment, the effect of Jukryuk and Saengkang-juices was determined by inducing cerebral vascular ischemia after occluding the middle cerebral artery (MCA) in mice, and making observations and comparisons such as alterations in damaged areas and neuronal cellular changes in the brain. Conclusions : According to the above results, Jukryuk and Saengkang-juices can protect the cerebral vascular ischemia.

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.
