摘要
本工作首次利用声源发作大鼠动物模型,以其行为表现分Ⅴ级,观察氯硝基安定短期处理组、长期处理组和对照组大鼠对铃声刺激后的行为表现,并对脑组织谷氨酸脱羧酶进行测定。结果显示:铃声刺激使对照大鼠全部惊厥;氯硝基安定短期处理后对铃声刺激无反应;而在氯硝基安定长期处理后,铃声刺激使大鼠的表现与对照组相似;而上述三组大鼠的脑组织谷氨酸脱羧的活性各组之间无显著性差异。提示:氯硝基安定能明显拮抗大鼠的声源性发作;但长期应用使抗痫作用明显下降,表现为耐受;这种耐受与谷氨酸脱羧酶无关。
To investigate the behavior and the ability of glutamic acid decarboxylase(GAD).the audiogenic seizure rats in control.short time and long time-clonazepam pretreated groups were used. The results showed that(1) The bell-stimulation made control rats convulsion;(2) short time- CZP pretreated rats did no response to bell;(3) Long time-CZP pretreated rats resembled with the control rats.The activities of GAD were not significant differences among control, short time-and long time-CZP pretreated gtoups The results suggested (1) CZP inhibit the convulsion of audiogenic seizure significantly, but long time CZP used ,the antiepileptic effects were diminished significantly,e.g.tolerance;the mechanisms of tolerance were not associated with GAD.
