Mouse neuroblastoma 2a (N2a) cells were treated by Kunnuetang, Duchang and Daejo. Result : 1. Kunnuetang, was effective on LDH assay of hypoxia and reoxygenation. 2. Duchang and Daejo were generally effective on LDH assay of hypoxia and reoxygenation. 3. In MTT assay of hypoxia Kunnuetang was not effective. Duchung and Daejo were not generally effective on MTT assay, but in certain condition Herbs were effective. 4. In MTT assay of reoxygenation Kunnuetang and Daejo were not effective. But Duchung was effective in certain condition. Conclusion : The results suggest that Kunnuetang, Duchang and Daejo may have protective effect on vascular dementia and ad patient.
