Percent increase in water content in tissue from the peri-contusion (rostral cortex) area compared to non-injured, distal cortical area from the same animals at 24 (A) and 48 (B) hours post-TBI in young (clear bars) and aged (gray bars) rats with cortical injury (L), sham surgery (S) followed by vehicle (SV and LV) or progesterone (LP) injections. Two-way ANOVA results are represented as mean ± SEM. Asterisk (*) indicates significant difference from other treatment groups within the same AGE group. Pound (#) denotes significant difference between young and aged subjects within the same treatment.
