Representative spinal cord sections stained with hematoxylin and eosin showing the cavities at 2 weeks after T9 clip compression injury taken at the epicenter and at 2 mm increments rostral and caudal in a rat receiving saline vehicle and a rat treated five times with valproic acid (VPA). Larger cavitation is evident in saline-injected group than the VPA-injected group, a progressive diminishment with distance from the epicenter of the lesion. Scale bar=500 µm; 5× magnification. SCI : spinal cord injury.
