Objective:To discuss the effects of yuxianling granule on brain-derived neurotrophic factor(BDNF)expression in hippocampus of epileptic rats and cognitive dysfunction.Methods:10 rats were taken as normal control from 150 rats,the other were given pentylenetetrazol(PTZ)to build models.Rats that consistent with the standard model were divided into 4 groups,yuxianling granule,lamotrigine,sodium valproate and model groups,applying opening experiment,experimental platform to test the study and memory capacity of rats;hippocampus BDNF expression was determined by immunohistochemical method.Results:T...
