Fig. 3.

Luxol fast blue-Cresyl violet stain of spinal cord tissue samples obtained from the level of the hemisection (Hemisection) and at sites 5 mm caudal to the hemisection (Hemisection-5 mm). The right column shows tissue from the dotted areas in the left column at higher levels of magnification. At the level of hemisection, the ipsilateral half of the spinal cord was completely destroyed, with necrotic tissue and glial nuclei observed. At spinal cord sites 5 mm caudal to the hemisection location, a vacuolation and infiltration of inflammatory cells (arrow) was observed in both dorsal and lateral funiculi. No obvious findings of neuronal necrosis were noted in the gray matter.
