| Abstract: | Zhenxuanyin symbol: see text] is composed of pure Chinese medicinal herbs, such as gastrodia tuber, poria cocos, ligusticum wallichii etc. 4-verssel occlusion (4VO) model rats were reperfused after 30 minutes' complete occlusion, and Zhenxuanyin was administered 3 times a day. 24 hours later, 123I-IMP uptake in the brain was evaluated as an index of cerebral blood flow (CBF). The results show that Zhenxuanyin (0.03 g/kg, 0.3 g/kg, 1 g/kg, or 3 g/kg a day) can greatly improve the blood flow in the main cerebral regions, and 0.3 g/kg can increase cerebral blood flow (CBF) to the normal level. |
