Abstract
The article reveals that a decrease in the background production of reactive oxygen species (ROS) in the peritoneal neutrophils of mice after a short-term (40 minutes) stay in hypomagnetic conditions (residual field 10 nT) at physiological temperatures, detected by the method of lucigenin-dependent chemiluminescence, is not accompanied by a violation of chemiluminescent response to respiratory burst activators: formylated peptide N-formyl-Met-Leu-Phe (fMLF) and phorbol ester of phorbol-12-meristat-13-acetate (PMA). These results were obtained by activated chemiluminescence using lucigenin or luminol and various combinations of ROS production activators (PMA and/or fMLF). In contrast, the action of combined parallel constant (induction 60 μT) and alternating (amplitude range 60-180 nT, frequency 49.5 Hz) magnetic fields (CMF) leads to a decrease in the chemiluminescent response to these activators. These data indicate different sources of ROS that respond to certain modes of CMF and hypomagnetic field in neutrophils. The conducted research and the previously obtained results enable to exclude the systems that control the respiratory burst in neutrophils from the main targets and acceptors that respond to short-term deprivation of the magnetic field.
