ABSTRACT
Objective To explore the changes of Nogo-A mRNA and Nogo receptor(Ng-R) mRNA expressions in hippocampus of immature rats after febrile seizures(FS).Methods One hundred and twenty-seven male SD rats(15 days) were randomly divided into control group(immersed in 37 ℃ water,n=40)and hyperthermia treated group(immersed in 44.5 ℃ water,n=87).The latter was further divided into febrile control group(n=42) and FS group(n=45) according to whether seizures occurred or not.Each group was further divi-ded into 5 groups according to different therapies(1,3,5,7,10 times treatment).Then 5 cases of the 8 rats were randomly used to observe the expressions of Nogo-A mRNA,Ng-R mRNA in hippocampus by using reverse transcriptase polymerase chain reaction(RT-PCR).Three of the 8 rats were randomly used to observe the changes of neurons and mossy fiber sprouting(MFS) in hippocampus by Nissl and Timm staining.Results 1.No seizures occurred in normal control group.Seizures occurred in 2 rats of febrile control group.In FS group,various seizures occurred such as nodding spasms,tonic seizures,clonic seizures and tonic-clonic seizures,2 rats died of drowning and 3 rats died of status epilepticus.2.The expressions of Nogo-A mRNA,Ng-R mRNA in the immature rats′ hippocampus became up-regulated after the 7th and 10th seizure,significantly higher than those of the other 2 control groups(Pa
