Changes of learning and memory and calmodulin dependent protein kinase Ⅱ expression in hippocampal neurons of pentylenetetrazole-kindled rats / 基础医学与临床

Objective To observe the effect of pentylenetetrazole(PTZ)-kindled epliepsy on rat's learning and memory and the expression of calmodulin dependent protein kinaseⅡ(CaMKⅡ)in hippocampal neurons.Methods The rats were injected intraperitoneally with PTZ to establish the kindled models.The changes of behavior were evaluated through Morris water maze and the expression of ?-CaMKⅡ in hippocampal neurons was observed by immunohistochemistry technique.Results The Morris water maze test showed that the escape latency and the swimming distance in PTZ-kindled rats increased significantly(P
