  • Title: [Antioxidant properties of UV-irradiated blood plasma as determined by the photochemiluminescence method].
    Author: Udilova N, Popov IN, Levin GI, Vladimirov IuA.
    Journal: Biofizika; 1997; 42(1):187-90. PubMed ID: 9181790.
    Abstract:
    UV-irradiation of human serum albumin, tryptophan, and histidine resulted in products formation showing antiradical activity, as detected by increased latent period in development of luminol photochemiluminescence. UV-irradiation of ascorbic acid decreased its antiradical activity. Under UV-illumination, antiradical activity of blood plasma decreased rapidly followed by a gradual increase of antiradical activity. Apparently, the former effect (decrease of antiradical activity) is a result of photolysis of natural blood antioxidants, while subsequent increase of antiradical activity is a consequence of the accumulation of plasma protein photolysis products.
