Effects of GCP II KO on GSH (a), MDA (b), SOD (c), GPx (d). TBI caused significant decreases of GSH level, SOD, GPx activities, and an increase in the MDA level. GCP II KO significantly moderated these changes while not altering the levels in sham controls. Data were represented as mean ± SEM (n = 6 per group); *p < 0.05, versus sham control of the same genotype; ^# p < 0.05, versus injured WT mice
