Anticonvulsant effect of ceftriaxone sodium in temporal lobe epilepsy
摘要
Abstract
Objective To study the effects of ceftriaxone sodium(Cef) on the seizures and the expression of glutamate transporter (GLT-1) in kainic acid (KA) epilepsy model.Methods Firstly, a chronic spontaneous seizure mouse model was established by unilateral hippocampal injection of KA and monitored by vEEG technique to record seizures.The experimental group received intraperitoneal injection of Cef 200 mg/(kg·d) and the control group received normal saline.Seizure frequency, interictal spike waves and histological phenotypes were recorded to evaluate the function of Cef.Then we use the Western blot to detect the effect of expression for GLT-1.Results Unilateral hippocampal injection of KA 200 ng successfully established the mesial temporal lobe epilepsy model.Cef can reduce the seizures from 2.145 times/day to 1.597 times/day, decreased by 31.2% with a statistical significance(P<0.05).Cef treatment did not significantly enhance the expression of GLT-1.Conclusions Intraperitoneal injection of Cef partially inhibites the seizures of KA model, but the expression of GLT-1 in hippocampus is not enhanced.It is suggested that ceftriaxone may inhibit seizures through other mechanisms.关键词
