Abstract
The damaged areas in the cerebral tissue exposed to CO2 laser irradiation in experimental animals and human cerebral tumors were investigated with light and electron-microscopy (LM & EM). After CO2 laser irradiation, a damaged area composed of a charred zone, a coagulation zone, and an edematous zone was observed under LM. However, at the ultrastructural level another zone 60 - 100 micrometers in width surrounding the edematous zone was found. Mitochondria swelling, dilatation of rough endoplasmic reticuli, and degeneration of synapses appeared in that zone which we named `periedema zone.'
