title: [Modification of damaging effect of ultraviolet radiation on peritoneal macrophage membranes in mice].
abstract: Different factors modificating damaging effect of middle-wave ultraviolet radiation (lambda max = 306 nm) on mice peritoneal macrophage plasma membranes were studied. It was shown that damaging effect of ultraviolet declined when the cells were simultaneously treated by red light (lambda max = 713 nm). This protective effect increased when a red component of light became greater and achieved almost 100% when it consisted 28.6%. It was also found that the decrease in intra- and extracellular pH led to the decrease in damaging effect of UVR. The increase of pH bring to an elevation of UVR destructive effect.
