目的：观察复方石菖蒲颗粒（CSCP）对戊四唑（PTZ）致痫小鼠行为及海马结构的影响。方法：昆明种小鼠60 只，雌雄各半随机分为6 组：空白组，模型组，苯妥英钠组，CSCP 高（4 000 mg·kg-1）、中（2 000 mg·kg-1）、低（1 000 mg·kg-1）剂量组，空白组和模型组给予等体积生理盐水除外，其他组别给予对应药物，连续灌胃7 天，末次给药1 h 后，按80 mg·kg-1 剂量腹腔注射PTZ（空白组除外），造成急性癫痫模型，观察CSCP 对PTZ 致痫小鼠的发作潜伏期、行为分级、发作次数等的影响；采用脑组织切片HE 染色观察海马结构的改变。结果：CSCP 可以改善癫痫小鼠的发作程度，延长轻度发作潜伏期，减少郁、吁级癫痫发作次数；观察HE 染色切片可见PTZ 致痫小鼠海马结构发生改变，细胞数量减少，苯妥英钠和CSCP 可有效保护小鼠海马神经元。结论：CSCP 对PTZ 致痫小鼠有一定抑制作用及减少海马神经元细胞的损伤，其抗癫痫机制有待进一步探讨。

This study was aimed to observe the effect of Compound Shi -Chang-Pu (CSCP) granula on behavior, structure changes of hippocampus with epileptic seizure of mice induced by pentyenetetrazole (PTZ). Sixty Kunming mice, which were half male and half female, were randomly divided into 6 groups, which were the blank control group, animal model, phenytoin (PHT) group, high-dose CSCP (4 000 mg·kg-1) group, middle-dose CSCP (2 000 mg·kg-1) group and low-dose CSCP (1 000 mg·kg-1) groups. The blank group and model group were given intragastric administration the same volume of saline, the others animals treated with continuous oral administration of drugs for 7 days. Intraperitoneal injection of PTZ (80 mg·kg-1) was given 1 h after the last medication to establish the acute epilepsy model (expect the blank control group). Observation was made on the influence of CSCP on incubation period, behavior degree and times of epileptic seizure among PTZ induced epilepsy mice, the structure changes of mice were detected by the brain tissue HE staining. The results showed that CSCP can improve the degree of seizure attack, prolong the incubation period of mild attack, and decrease Ⅳand Ⅴdegree epileptic seizure, the PTZ induced epilepsy mice could damage the structure of hippocampus, reduce the number of cells, PHT and CSCP could ameliorate these changes. It was concluded that CSCP had certain inhibition on epileptic seizure mice induce by PTZ and ameliorate the damage of hippocampus. The antiepileptic mechanism still requires futher study.
