Sodium flourescein (NaFl) leakage as a marker of BBB disruption in RT and HAT hypoxic animals. Sections from control rats injected with NaFl show no leakage in the brain tissue of the frontal (top) and parietal (bottom) cortexes. In contrast, sections from the brain of 1 or 2 days of RT-hypoxic rats show moderate monofocal leakages in the frontal and parietal cortexes. Sections from the brain of 1 or 2 days of HAT plus hypoxia show multiple focal regions of NaFl in the brain tissue. Scale bar, 100 μm.
