| Research Abstract |
We have evaluated the hypothesis that apoptosis can cause hippocampal cell death induced by intra-amygdaloid injection of kainic acid (KA) in rats, which is an animal model of the hippocampal sclerosis in human temporal epilepsy. With in situ end labeling method, we have examined as early as 18h post KA injection nuclear staining located in the CA3 area of the hippocampus ipsilateral to the injection site. By the seventh day post KA injection, most of the ipsilateral pyramidal cells were positive. It is suggested that the distant brain damage originated from the amygdala by KA injection could induce apoptoic cell death in the ipsilateral hippocampus.
