[Morphological characteristics of skeletal muscle after damage by a laser scalpel].

Changes in the skeletal muscles provoked by carbon dioxide laser in white rats were studied histologically, biometrically and electron microscopically. The laser wound is characterized by coagulation necrosis, vacuolization, the absence of hemorrhages, decrease of edema and leukocytic infiltration. Laser hyperthermia produces local submicroscopic alterations in the muscle tissue. Histologically the borders of the zone affected are formed 3 days later. Preliminary administration of the liquid into the muscle results in a considerable decrease of the necrotic zone size.
