title = "Photochemically induced spinal cord injury in the rat",
abstract = "We have developed in the rat a minimally invasive model of reproducible spinal cord injury initiated photochemically. With the exposed spinal column intact, 560 nm irradiation of the translucent dorsal surface induces excitation of the systemically injected dye, rose Bengal, in the spinal cord microvasculature. The resultant photochemical reaction leads to vascular stasis. Histopathological changes at 7 days include hemorrhagic necrosis of the central gray matter, edematous pale-staining white matter tracts and vascular congestion. At the level of cord irradiation (T8) the entire cord thickness is necrosed except for the periphery of the anterior funiculus. Voluntary motor function is consistently lost in the subacute phase of injury.",
