title: Combined effect of X-ray radiation and static magnetic fields on reactive oxygen species in rat lymphocytes in vitro.
abstract: The aim of this study was to investigate the effect of static magnetic fields (SMF) on reactive oxygen species induced by X-ray radiation. The experiments were performed on lymphocytes from male albino Wistar rats. After exposure to 3 Gy X-ray radiation (with a dose rate of 560 mGy/min) the measurement of intracellular reactive oxygen species in lymphocytes, using a fluorescent probe, was done before exposure to the SMF, and after 15 min, 1 and 2 h of exposure to the SMF or a corresponding incubation time. For SMF exposure, 0 mT (50 µT magnetic field induction opposite to the geomagnetic field) and 5 mT fields were chosen. The trend of SMF effects for 0 mT was always opposite that of 5 mT. The first one decreased the rate of fluorescence change, while the latter one increased it.
