Abstract

Objectives : In this study, aged BCAO rats were used to observe the effect of Bupleuri Radix on brain ischemic injury because aging is an important factor in storke. Methods : The brain ischemic injury was induced by temporary closing carotids on both sides in a low blood pressure state, and Bupleuri Radix was orally administered to 18 month-old BCAO rats. The ischemic damaged hippocampus and c-Fos and c-Jun expression were analyzed by the immunohistochemical staining. Result and Conclusions : Results are summarized as fellows; 1. The c-Fos expression after inducing a brain ischemic injury in the hippocampus was more inhibited in the experimental group than in the control group. 2. The normalized optical density of c-Fos expression was more reduced in cornu ammonis(CA)1, dentate gyrus(DG) areas in the experimental group than in the control group. 3. The c-Jun expression after inducing a brain ischemic injury in the hippocampus was more inhibited in the experimental group than in the control group. 4. The normalized optical density of c-Jun expression was more reduced in CA1 and DG areas in the experimental group than in the control group.
