Paper Abstract

It has been shown that NO is released under the exposure of the aqueous solutions of S-nitrosocompounds as well as blood plasma proteins and whole blood of healthy donors to UV and visible light. In addition to NO, thyil radicals which dismutate to disulfides, are formed under anaerobic conditions. In the presence of oxygen, peroxide compounds, cysteine acids derivatives are formed apart from disulfides, and NO is mainly converted to NO2-. It is suggested that NO released under the action of UV and visible light from physiological depots induces vascular relaxation, which enhances the blood flow.
