Study on cognition disorder and morphologic change of neurons in hippocampus area following traumatic brain injury in rats.

To explore the correlation between cognition disorder and morphologic change of hippocampal neurons after traumatic brain injury (TBI).Wistar rat models with severe TBI were made by Marmarou's method. The histopathological change of the neurons in the hippocampus area were studied with hematoxylin-eosin (HE) staining and terminal deoxynucleotidyl transferase-mediated X-dUPT nick end labeling (TUNEL), respectively. The cognitive function was...
