P. copri treatment attenuated oxidative stress after TBI. A-E. The changes of oxidative stress markers in the brain lesion area after TBI were detected by spectrophotometer. A. SOD activity. B. CAT activity. C. ROS level. D. GSSG level. E. GSH/GSSG ratio. *, p < 0.05 vs. sham; #, p < 0.05 vs. TBI. n = 6 per group. One-way ANOVA was used to compare the means of different groups followed by a Tukey post hoc multiple-comparisons test
