Evaluation the Efficacy of Sodium Valproate and Low Frequency Stimulation During CA1 Hippocampal Kindling on Anxiety-Like Behavior in Adult Male Rat

Background and Aim: Emotional disorders are prevalent in many epileptic patients. So, in this research, we have studied the efficacy of two treatment methods of seizure on anxiety-like behavior during kindling in adult male rat. Materials and Methods: 42 male rats were randomly divided into 6 groups: Control, Sham operation, saline-kindled and drug-kindled groups which have received saline or drug 15 minutes before kindling stimulations, and saline-kindled-LFS or drug-kindled-LFS group which have received saline or drug 15 minutes before kindling stimulations and LFS applied after termination of kindling stimulations. Anxiety-like behavior was assessed on the 6th day by using elevated plus maze and open field apparatus. Findings: kindling significantly increased open arms (OAs) entries percentage, OAs exploration percentage, increasing jumping from elevated plus maze (p<0.001) and rearing frequency in open field apparatus (p<0.05) compared to the sham group. Sodium valproate increased OAs entries percentage and OAs exploration percentage in drug-kindled group compared to sham group (p
