FIG. 7.

(A) Immunostaining for rat immunoglobulin G (IgG) as an indicator for compromised blood-brain barrier. (B) Relative optical density (OD) of full coronal sections from the brain of a single rat exposed at 190 kPa. The OD of each section was divided by average OD of three controls (two naïve and one sham). Inset illustrates brain region covered in this study. (C) Average relative OD of IgG across the brain parenchyma for rats exposed to primary blast and sacrificed 24 h post-exposure. Error bars are standard deviation.
