FIG. 2.

ABCC1 immunoreactivity in control cases (A–E) and patients with TBI (F–K). ABCC1 was identified colorimetrically using diaminobenzidine (brown), and sections were counterstained with hematoxylin. A, B. Control 6. C–E. Control 7. F. TBI patient 8. G. TBI patient 9. H–J. TBI patient 10. K. TBI patient 6. Images were taken at 40×; highlighted are ABCC1 immunoreactive cells with the morphologic appearance of neurons (black block arrows) or astrocytes (white block arrows), and other nonvascular immunoreactive cells (arrows).
