[Alteration of intracellular pH of macrophages after UV-irradiation].
It was shown that in vitro exposuse of mice peritoneal middle-wave ultraviolet radiation (lambdamax = 306 nm) in doses which don't damage to cause plasma membrane caused dose-dependent decreasing of their intracellular pH. After exposure of cells to 0.5 J/cm2 it was detected an acidification of intracellular contents followed by an increase of intracellular pH up to control level (after 40 min of incubation) and then above it (on 45 min of incubation). An increase of irradiation dose was accompanied by more evident reduction of intracellular pH and lack of its restoration on 45 min of postradiational incubation under irradiation with a dose of 3 J/cm2.
