ABSTRACT
Aim To investigate the hippocampal neuronal injury induced by ?-amyloid peptide ( A?) in rats and the candidate contribution of JNK signal transduction pathway to A? toxicity. Methods Rats were bilaterally injected with A?1 -40 into hippocampi CA1 area. The pathological changes,survival and apoptosis,and ultrastructure of hippocampal neurons,as well as p-JNK positive cells were observed by HE staining,Nissl staining,TUNEL staining,immunohistochemistry and transmission electron microscopy,respectively. Results Thepyramidal cells in hippocampus arranged loosely with decreased cell number. The gliacytes significantly proliferated. Significant apoptotic features were observed in CA1 ultrastructure. TUNEL-positive cells and p-JNK-positive cells significantly increased ( P
