Hippocampal Bcl2 mRNA Levels in EPOCCI and VEHCCI rats obtained at post injury days (PID) 1, 2, 3, 7, and 14, presented as a percentage of corresponding Sham mRNA. Contralateral and Ipsilateral hemispheres are abbreviated as contra and ipsi, respectively. EPOCCIcontra and ipsi are shown as light gray and white bars, respectively. VEHCCI contra and ipsi are shown as dark gray and black bars, respectively. Results are presented as percent Sham mRNA±SEM, n=6–8/group. *p<0.05 relative to VEHCCI; &p<0.05 relative to SHAM. Bcl2 mRNA increased relative to VEHCCI at PID2 (in contralateral hippocampi) but decreased relative to VEHCCI in both hippocampi at PID3.
