초록
Objective : In this study old BCAO rats were observed for effects of 'Dea-Hwang' on brain ischema injury, because risk of stroke increases with age. Method : The brain ischema injury was induced by temporarily closing carotids on both sides in a low blood pressuer state and Dea-Hwang was administered orally to 18 month-old BCAO rats. Results and Conclusions : The ischemically damaged Hippocampus and c-fos and c-jun expression were analyzed by immunohistochemical staining and results are summarized as follows: 1. The c-fos expression after inducing a brain ischema injury in the hippocampus was more inhibited in the dosed group than in the control group. 2. The normalized optical density of c-fos expression was more reduced in the CA1, CA2, and DG areas of the dosed group than in those of the control group. 3. The c-jun expression after inducing brain ischema injury in the hippocampus was more inhibited in the dosed group than in the control group. 4. The normalized optical density of c-jun expression was more reduced in the CAI area of the dosed group than in that of the control group.
