Comparative analysis of light effect generated by various light sources on the capacity of neutrophils

Using the whole blood of 60 healthy volunteers the effect of light generated by incandescent lamps, luminescent lamps and light-emitting diode carriers on the capacity of neutrophils considering the indices of lysosomal, phagocytic and NBT-reducing activities after 10, 20 and 30 minutes of influence at the temperature of 37 °С has been studied. The light temperatures were 4000-5000 K, the radiation intensity was 0,03 W/m 2, the wave length was 320-400 nm. It's stated that the light generated by incandescent and light-emitting diodelamps doesn't have a statistically significant effect on the capacity of neutrophils. The increase of cells number has been recorded in the spontaneous and induced NBT-test after the effect of luminescent lamps.
