[Functional and structural changes in the surface of human erythrocytes after irradiation with UV rays of various wave lengths. II. Alcian blue sorption by the outer membrane components].

Irradiation of erythrocytes with UV light (254 nm) in doses, which increased the activity of ABO and Rh system antigens followed by a photochemical destruction of the cell surface coat (outer perimembraneous layer) and the release of its components, which were stained in situ with alcian blue vital dye to be presumably glycoproteins. The role of this phenomenon in the therapeutic effect of UV light is discussed.
