Modulation with bupleurum root on brain electrical activities in epileptic model

Aim: To study the effect of bupleurum root on epileptic seizure. Methods: The rabbits and rats were injected by pilocarpine as epileptic models, and observed the effect of bupleurum on the electroencephalogram(EEG) and hippocampal slice by electroencephalograph and glass microelectrode extracellularly. Results: The seizure time and duration of each major seizure of epilepsy were significantly shortened and the interval of seizure significantly prolonged ( P <0.05)after intraabdominal injection of bupleurum root.After instilling the injection of bupleurum root onto the slices could reduce the amplitude of evoked field potential in epileptic hippocampal slices remarkably, the average of fall is 20.41% ,and restore in 6.86 minutes on average( P <0.001).Conclusion: Bupleurum root can inhibit the brain electrical activities in epileptic model, it is suggest that bupleurum has the distinct effect of antiepilepsy.
