[Effects of ultraviolet irradiation on structural and functional condition of T- and B-lymphocytes of human blood].
The influence of ultraviolet (UV) radiation on structural and functional condition of membranes T- and B-lymphocytes of human blood is investigated. It is shown, that intergral flow of UV-light (240-390 nm) in doses 151-1359 J/m2 leads to the increase of the expression of some HLA-antigen (DR1, DR2, DR5, DR7) and Fc-receptors on membranes of B-lymphocytes. The level of HLA-antigen was increased by 20-500% from the initial state after exposure to different doses. The growth of the expression of Fc-receprots was registered in 80% of the donors in the range from 20 up to 540%. The minimum dose of UV-light (151 J/m2) caused the maximum effect. The reduction of the level of Fc-receptors by 10-90% relatively to the native condition was registered for T-cells in 80% of the donors. Groups of the donors were revealed, T-lymphocytes of which differed by the sensitivity to UV-radiation. The effect of "strengthening--weakening", resulting to the reduction of the initially high parameters and to increase in the initially low ones was found.
