Abstract

Based on the model of the two calcium stores developed by Goldbeter, and the viewpoint that the cell membrane is a major site of interaction for extremely-low-frequency (ELF) electromagnetic fields, the permeability of ions can be changed by electromagnetic fields, a theoretical model of cytosolic calcium oscillations influenced by magnetic fields is presented. It is shown that, the field frequency condition will influence the pattern of calcium oscillation while the field strength was given, and the magnetic field strength will change the pattern of calcium oscillation when the frequency was 50Hz and 100Hz. Therefore, intracellular calcium oscillations can be influenced by ELF magnetic fields and then a series cellular response could be transformed.
