[Study of the effects of laser irradiation (540 nm) on some components of blood enzyme antioxidant system]. / Izuchenie vliianiia lazernogo izlucheniia (540 nm) na otdel'nye zven'ia fermentativnoi antioksidantnoi sistemy krovi.

The influence of blood laser irradiation (lambda = 540 nm) in doses range 0.3-1.2 J/cm2 on the neutrophyles superoxide-dismutase and katalase activity has been studied. Correcting effect of laser light (0.6; 1.2 J/cm2) on the functional activity of studied enzymes has been found. The high degree of correlation (r = 0.6) between neutrophil superoxide dismutase and neutrophil catalase activity of the irradiated blood has been discovered. The close correlation between components of the antioxidant system and processes of active oxygen metabolite generation has been revealed. The scheme of free radical mechanisms of the laser irradiation influence on the several parts of the enzyme antioxidant system has been suggested.
