[Histochemistry of proteins and their functionally active groups in the skin of the neck and mucous membrane of the oral cavity of white rats in the zone exposed to a helium-neon laser].

The author made experiments on 49 white rats exposing their cervical skin ano oral cavity mucous membrane to the irradiation beam of a 40 mvt helium-neon laser (lambda 6328A) during 10-15 minutes. The reactive capacity of proteins was found to have intensified and the content of functionally active groups, especially SH. to have increased as well as well as the activity of the cytochromozydase. When the exposition to laser irradiation was raised to 30 minutes pronounced morphohistochemical lesions were noted in the cervical skin and oral cavity mucous membrane. The data received may be useful in clinical practice for the application of low-power laser irradiation of 6328A wave length for stimulation of metabolic processes.
