Delayed increase in labeling of (A) [4-13C]glutamate(GLU C4) and [3-13C]glutamate (GLU C3), (B) [4-13C]glutamine (GLN C4) and [3-13C]glutamine (GLN C3) and [2-13C]GABA (GABA C2) and (C) [3-13C]GABA (GABA C3) in ipsi and contra sides of the brain from young TBI rats at 15, 30 and 60 min after i.p. injection of [1,6-13C]glucose. These time points represent 5h15min, 5h30min and 6h post TBI injury. Values are mean ± S.E. of data for nmol 13C incorporated/mg protein from 6 TBI and 5 sham rats at each time points. Data were analyzed using one-way ANOVA. *p<0.05 significant difference between ipsi and contra sides of TBI and sham brain as indicated the horizontal lines over the bars.
