Effects of Baixiangdan capsule on learning and memory in PMS rat model with liver-qi invasion syndrome / 中国药理学通报

Aim To explore the effects of Baixiangdan capsule on learning and memory in PMS rat model with liver-qi invasion syndrome. Methods Liver-qi inva-sion rat model was prepared using foot-shock and noise stimulation, and then the model was treated with drugs, finally all the group of rats were evaluated using open-field test. We also detected learning and memory function of PMS liver-qi invasion rats model using Y-maze, new-object recognition and Morris water maze test. Results Compared with the normal group, the total distance increased significantly, number of crosses into the central area and duration of movement in the central area decreased significantly in model group. The total distance decreased significantly, number of crosses into the central area and duration of movement in the central area increased significantly in Baixiang-dan treatment group compared to the model group, and the total distance decreased significantly in fluoxetine treatment group compared to the model group. Com-pared with the normal group, DI decreased significant-ly in model group, and DI increased significantly in Baixiangdan treatment group. During place navigation training, the model group’ s escape latency was obvi-ously delayed on 2nd, 4th day. Compared with the model group, Baixiangdan and fluoxetine treatment group’ s escape latency was obviously reduced. During spatial probe test, compared with the normal group, the escape latency was obviously delayed, and the number of crossing platforms was significantly reduced in the model group. Compared with the model group, the number of crossing platforms significantly increased in Baixiangdan treatment group. Conclusion PMS liver-qi invasion rat model presents learning and memo-ry damage, which could be improved by Baixiangdan capsules, and the treatment effect may be superior to that of fluoxetine.
