Abstract:
Objective To explore the mechanisms and the significance of compatibility of Heixiaoyao Powder by observing the effect of Heixiaoyao Powder on mice model of senile dementia induced by scopolamine. Methods Kunming mice were randomly divided into five groups including control group, model group, Heixiaoyao Powder group, Xiaoyao powder group and streamlined formula group, with 10 mice of each group. Scopolamine hydrobromide intraperitoneal injection was adopted to make memory impairment in mice model, and followed by drugs treatment with corresponding decoction of the crude drug 2.314 g /(kg·d). Control group and model group were given normal saline orally once a day, all groups were treated for 10 days continuously. After 6 and 8 days of the administration, water maze test, stair jumping test and darkness avoidance test were conducted to test behavior proficiency, and the activity of acetylcholinesterase (AchE) activity and choline acetyltransferase (ChAT) in brain tissue were tested also. Results Compared with model group, Heixiaoyao Powder group, Xiaoyao Powder group and streamlined formula group could significantly reduce the error number and shorten latency in the water maze test, decrease the time of electrical shocks and prolong the incubation period of time in both stair jumping test and darkness avoidance test, and could increase ChAT activity and lower AchE activity in brain tissue of mice (P<0.01 or P<0.05), especially the effects of Heixiaoyao Powder group. Conclusions Heixiaoyao Powder and its analogous formula have the function of preventing and treating senile dementia.
