Abstract:
Objective To investigate the mechanism of presynaptic protein (Munc18) antibody in inducing epilepsy on rat. Methods Munc18 antibody was continuously micro-injected into CA1 area of hippocampus in Sprague-Dawley (SD) rat (the injection times were nine). The potential epileptic seizure was evaluated according to both electroencephalogram (EEG) and behaviors. HE, Nissle and TUNEL staining were applied on rat brain sections as to detecting the cell damage and apoptosis after tenth week. Results Ten of twelve rats produced epileptic EEG, five cases among these ten rats maintained abnormal EEG after the sixth week since injections. Nine of the above twelve rats had epileptic seizure according to Racine grade one to four, four cases among these nine rats kept seizure after the sixth week since injections. The number of neurons decreased (155?20,P
