Objective To observe the effect of vagus nerve stimulation(VNS)on expression of Connexin 43(Cx43)of astrocytes in hippocampus of rat with epilepsy induced by kainic acid(KA),and investigate the relationship between Cx43 and epilepsy as well as role of Cx43 in treatment of epilepsy by VNS. Methods SD rats were randomly divided into control,KA and VNS + KA groups,10 for each. The rats in KA and VNS + KA groups were injected with 3 μl of0. 05% KA into lateral ventricle to establish the model of epilepsy,while ...
