ABSTRACT
This study was aimed to investigate the effect of Radix Bupleuri extract (RBE) on 5-HT3R channel currents of primarily cultured hippocampal neurons in depression emotion rats.Depression emotion model ratswere duplicated.RBE was used for drug intervention.And then,the rats were evaluated by the open-field test (OFT) and the sucrose preference test.Serum of rats in each group was collected and then added into the primary cultured hippocampal neurons for 24 h.The 5-HT3R channel currents were recorded by the whole-cell patch clamp.The results showed that compared with the normal group,the total score of OFT in the model group was significantly decreased (P < 0.01); the sucrose preference ratio decreased obviously (P < 0.01); and the current density value of primary cultured hippocampal neurons in serum of the model group was significantly higher (P <0.01).Compared with the model group,the total scores of OFT in the RBE group and fluoxetine group increased significantly (P < 0.05,P < 0.01); the sucrose preference ratio also increased obviously (P < 0.05,P < 0.05); and current density value of the primary cultured hippocampal neurons in serum of the RBE group and fluoxetine group decreased significantly (P < 0.01,P < 0.01).It was concluded that RBE can effectively correct the abnormal 5-HT3R channel currents of rats with depression emotion,which may be one of the central mechanisms in the treatment of depression emotion.
