TIME DYNAMICS OF PRODUCTION OF REACTIVE OXYGEN SPECIES BY NEUTROPHILS AFTER TREATMENT UNDER HYPOMAGNETIC CONDITIONS

Abstract

. It was shown that incubation of a suspension of mouse peritoneal neutrophils for 30 minutes under hypomagnetic conditions obtained using permalloy magnetic screens (a constant magnetic field of not more than 20 nT, the level of variable man-made noise is reduced to a few nT) causes a significant decrease (about 48%) signal intensity of lucigenin-dependent chemiluminescence measured immediately after incubation. 20 minutes after magnetic treatment (followed by incubation in a geomagnetic field during this time, induction 44 μT, the level of magnetic interference at a frequency of 50 Hz was 15-50 nT), the differences between the control and experimental groups remain completely (the difference was about 49%). In 40 and 60 minutes after exposure to the "zero" field, followed by keeping the samples in the geomagnetic field for the specified time intervals, the difference between the control and experimental samples decreased to 32% and 22%, respectively. This effect was registered without additional activation of neutrophils by chemical agents initiating respiratory burst, such as N-formyl-Met-Leu-Phe formylated peptide or phorbol-12-meristat-13-acetate phorbol ester, and was not associated with effects on cellular systems, providing this explosion.
