Published in: Cell Mol Biol 2001; 47: OL115-OL117

Aim of study (acc. to editor)

To study the effects of a 50 Hz electromagnetic field on cell proliferation of the human leukemic monocyte cell line U937.

Investigated system:
Time of investigation:
  • before exposure
  • during exposure
  • after exposure

Main outcome of study (acc. to author)

The data showed no difference between exposed cells and control cells in the range of 0.3-2 mT. However, stronger fields (≥2.5 mT) inhibited cell division. Magnetic fields of ≥3.5 mT killed ≥80% of the cells at the beginning.
