ABSTRACT
OBJECTIVE: To study the effects of the active components of Xiaoxuming Decoction (XXM), a compound traditional Chinese herbal medicine, on chronic cerebral ischemia in rats.METHODS: Chronic cerebral ischemia was induced in rats by occlusion of bilateral common carotid arteries. Then, the rats with chronic cerebral ischemia were randomly divided into five groups: model group, extract of Ginkgo biloba group and low-, medium- and high-dose active components of XXM groups. Another 11 rats without occlusion of common carotid arteries were used as the sham-operation group. Memory behavior was investigated by Morris water maze test. The structure of hippocampus and cortex neurons was observed with Nissel staining. The white matter lesion was stained with Kl├╝ver-Barrera stain method to observe the pathological changes. The astrocyte activation was observed using immunohistochemical method with glial fibrillary acidic protein (GFAP) antibody. RESULTS: The active components of XXM could significantly improve the impairment of learning and memory induced by chronic cerebral ischemia in rats. Compared with the model group, the time to reach the platform for rats was shortened by treating with the active components of XXM in Morris water maze test, particularly in the medium-dose group (P
