利用大鼠脑内注血模型，观察比较了逐瘀化痰汤、三生饮、抵当汤对大鼠脑电不同时相频率、波幅、θ波指数的影响。结果显示，给药３组耐缺血缺氧程度显著优于造模加生理盐水组。给药组间比较，对频率和波幅的影响，三生饮组、逐瘀化痰汤组优于抵当汤组，而对θ波指数的影响，逐瘀化痰汤组优于抵当汤组、三生饮组。 The rat brain blood injection model was used to observe the effects of Zhuyu Huayu Decoction, Sanshengyin, and Biedang Decoction on the frequency, amplitude and theta wave index of EEG in rats. The results showed that the degree of tolerance to ischemia and hypoxia in the three groups was significantly better than that of the model plus saline group. In the comparison between the groups, the effect of frequency and amplitude, Sanshengyin group and Zhuyuhuayu decoction group was better than that of the Bidantang group, but the effect of the theta wave index was better in the Zhuyuhuayu decoction group than in the Bitangtang group. Sanshengyin group.
