Methods: 37 male Wistar rats were randomly divided into normal control group (n= 10), sham-operationgroup (n= 10), acute cerebral ischemia (ACI) + drug group (model group, n=8)and ACl+drug+acupuncture group(acupuncture group, n=9). Rat ACl model was established by using photochemical method. "Neiguan"(PC 6) and"Shuigou"(GV 26) were punctured and stimulated with both hand manipulation and electroacupuncture, 30 min and16hrs after ACI. TMP was given to the rats of the later 2 groups using gastric perfusion method. High pressure chro-matography (HPLC) was used to detect the target absorption level of TMP in the brain. Results: The content of TMP inthe brain in acupuncture group was significantly higher than that in model group (P＜0.01), suggesting that acupunc-ture can strengthen the brain-taxis of TMP in ACl rats, and combined administration of acupuncture and Chinese drugmaybe work better for treatment of acute cerebral infarction. Conclusion: Acupuncture can strengthen the chano-taxisof TMP to the brain in ACl rats. 收起
