The animals with poisoning died due to respiratory failure caused by persistent tetanic convulsion .

中毒动物因持续 强直 性 惊厥导致呼吸衰竭死亡。

Method : The epileptic seizure of mouse were induced by PTZ as model the tentative seizure incubation period of seizure and the case of tetanic convulsion were recorded to study the antiepileptic effect of SSa on mouse induced by PTZ .

方法：采用PTZ诱导小鼠急性痫性发作来复制癫痫模型，通过记录小鼠痫性发作潜伏期和 强直 性 惊厥率的变化，研究SSa抗小鼠PTZ致痫作用。

Also intraperitoneal injection of SSa could prolong the incubation period of tetanic convulsion in the group of 60 min 90 min and 120 min ( P < 0.05 ) . The effect was especially evident in the group of 90 min ( P < 0.01 ) .

在60、90、120min组中，SSa腹腔注射也能明显延长 强直 性 惊厥潜伏期（P<0.05），其中尤以90min组作用显著（P<0.01）；
