In paraformaldehyde-fixed sections of healthy brain, glial cells at the light-microscope level do not contain measurable levels of NADPH-diaphorase. However, after a variety of lesions in the mouse brain, some reactive astrocytes express varying amounts of this enzyme. Following stab wounds, activated astrocytes or related glial cells surrounding the(More)
Photodynamic therapy uses nonthermal coherent light delivered via fiber optic cable to locally activate a photosensitive chemotherapeutic agent that ablates tumor tissue. Owing to the limitations of light penetration, it is unknown whether photodynamic therapy can treat large osseous tumors. We determined whether photodynamic therapy can induce necrosis in(More)
