柴胡皂甙对癫痫大鼠脑电的影响

目的 观察柴胡皂甙对癫痫大鼠脑电的影响,探讨柴胡皂甙抗癫痫作用。方法 用8周龄健康SD大鼠,随机分为6组,正常对照组(A)、癫痫模型组(B)、拉莫三嗪组(C)、柴胡皂甙小剂量组(D)、柴胡皂甙中剂量组(E)和柴胡皂甙大剂量组(F),每组10只。后5组动物用青霉素致痫,在成功造模及用药物治疗后,分别检测脑电图和观察痫性发作行为。结果 A组脑电图正常,B组脑电图显示明显癫痫放电,C组和F组癫痫大鼠脑电图恢复正常,D组大鼠脑电图有少量癫痫放电,E组大鼠脑电图基本恢复正常。C、D、E、F组与B组脑电图相比较有显著性差异(P<0.001)。结论 柴胡皂甙对癫痫大鼠脑电图及痫性发作有明显改善作用。

Effect of saikosaponins on epileptic rat electroenciphalogram

Objective To study the effect of saikosaponins on the electroencephalogram (EEG) of epileptic rats to evaluate its therapeutic effect against epilepsies. Methods Sixty 8-week-old healthy SD rats were randomized into normal control group (A), epileptic model group (B), lamotrigine group (C), and 3 saikosaponin groups of small, moderate and high doses (D, E, and F groups, respectively), with 10 rats in each group. Penicillin was used to induce epilepsy in the latter 5 groups, and the EEG and onset of epileptic seizures were observed in each group. Results In group B, the EEG contained obvious epileptic discharges, which were not found in that in group A. After treatment with saikosaponins and lamotrignie, the EEG of group C and F became normal, whereas the EEG in group D still contained epileptic discharges at a low level, and that in group E was basically normal. The EEGs of group C, D, E, and F were significantly different from that in group B (P<0.001). Conclusion Saikosaponins can obviously alleviate the severity of epileptic seizure in epileptic rats.
