EFFECT OF RED LED RADIATION ON BIOAMINSINFLOWING SKIN STRUCTURES
Monochrome red LED light daily affects the person, as red monochrome LED lamps are a popular element of interior design of living and entertainment spaces. The influence of monochromatic radiation has not been studied sufficiently, in connection with the recent commencement of their production on an industrial scale. This work is devoted to revealing structural changes in the skin of experimental mice after irradiation with their LED light at a wavelength of 690 nm (red light). The authors detected biogenic amines in the granular luminescent (GLC) and mast cells (MC) of the dermis, as well as in the epidermis, hypodermis, and in the hair follicles during a luminescence-histochemical study of the skin of the control group mice. It was revealed that irradiation of mice with red LED light reduced the content of histamine, serotonin (ST) and catecholamines (CA) in the studied structures. In the intercellular environment of GLC and MC, a decrease in biogenic amines was also detected. The greatest decrease in neuroamines after exposure to red light was observed in the epidermis and hair follicles. It was revealed that the serotonin index in the mice of the experimental group did not change in comparison with the control group.
