Effects of electric stimulation on Nogo-A expression in hippocampus of rats / 中华物理医学与康复杂志

ABSTRACT

Objective To explore the effects of chronic electrical stimulation (ES) on Nogo-A expression in the hippoeampus of rats.Methods Thirty male Wistar rats were randomly divided into a control group and 4 exper- imental groups.The rats in the control group were given sham ES,while those in the experimental groups received 1, 3,6,or 9 days of ES before being sacrificed for the detection of Nogo-A expresson in the hippoeampus by immunohis- tochemistry and Western plotting.Results There was a positive correlation between the level of Nogo-A expression and the duration of ES,as shown by the immunohistochemistry technique.Western blotting showed the same result. Conclusion In general,seizure occurred 8 days after electrical stimulation began.Elevated Nogo-A expression in the hippocampus began earlier than seizures in the epilepsy model groups.
