ABSTRACT

Objective To explore the effect of antiepileptic drugs on rats' cognitive function. Methods 70 adolescent male SD rats, weighing (201?29)g, were randomly divided into seven groups: normal control group (NS), status epilepticus group (Pentylenetetrazole, PTZ), carbamazepine group (CBZ), valproate sodium group (VPA), phenytoin group (PHT), topiramate group (TPM) and lamotrigine group (LTG). All animals except those in NS group were kindled by PTZ, then they were treated with antiepileptic drugs (AEDs). Rats of all the seven groups were subjected to Morris water maze test two weeks later. Results The average time spent by the rats of TPM group was longer than that by other groups in each test (P

ABSTRACT

Objective To observe the effects of interical epileptiform discharges (IED) on emotional behavior and spatial learning and memory of rats.Methods 76 male Wistar rats were divided randomly into 4 groups. Group HK/SE (n=23) for kindling with rapidly recurring hippocampal seizure followed by subconvulsive electrical stimulation to hippocampus 13 days later. Group HK (n=20) for hippocampal kindling. Group SE (n=17) for control of electrode implanted in hippocampus without stimulation, and Group NC (n=16) for normal control. The emotional behaviors of experimental animals were tested by the activity in an unfamiliar open field and resistance to capture from the open field, as well as their spatial learning ability in the Morris watermaze.Results The IED rats in Group HK/SE tested 14 days after hippocampal kindling displayed substantial decreases in open-field activity (scale: 17.3?3.6 for NC group, and 4.6?1.3 for IED rats, P
