Histopathological characterization of photochemical damage in nervous tissue

Abstract

This paper discusses histological and ultrastructural changes produced by dye-sensitized photoreactions in the central and peripheral nervous system. Particular attention has been given to morphological outcome in experimental models which reproduce widespread clinical pathologies, e.g. stroke, spinal cord injury and peripheral neuropathy. Evaluation of structural alterations may not only help to characterize the evolution of these disease processes but also allow us to study possibilities of therapeutic intervention
