Results for cortical GFAP reactivity proportional area at PID 3 and PID 7 are shown graphically on the left. REGCCI and DHACCI are shown in solid black and white bars, respectively, while corresponding SHAM groups are shown as spotted gray and latticed white for SHAMREG and SHAMDHA rats. CCI significantly increased GFAP reactivity in the cortex at both PID 3 and 7 relative to SHAM controls (&p=0.001 main effect of injury, adjusted p value p<0.01 at PID3 and p<0.05 at PID7). DHA treatment did not affect increased GFAP reactivity at either time point (p>0.25 main effect of treatment. On the right, representative images of cortical GFAP reactivity are shown for SHAMREG, REGCCI and DHACCI. The scale bar is 100 microns.
