FIG. 4.

The extracellular N-acetylaspartate (eNAA) concentrations in microdialysis samples from six non- traumatic brain injury (TBI) patients vs. those measured in 30 non-TBI patients at time-points taken after 96 h post-injury. The 30 TBI patients are divided into two groups; the TBI patients of which four received non-supplemented perfusion fluid and 15 received perfusion fluid supplemented with 4 mM glucose, and the time-course TBI patients who received non-supplemented perfusion fluid. Graphs were plotted from 24 h pooled samples for the non-TBI and TBI patients (n = 6 and 22, respectively), and 8 h pooled samples from the TBI time-course patients (n = 8).
