[Mammalian cell culture reaction to the action of a constant magnetic field of 1000 and 3000 Oe intensity].

The effect of a constant magnetic field of 1000 and 3000 oersted on mammalian cell cultures was examined. The effect of prolonged (12 days with three successive subcultures) and short-term intermittent action (repeated 6 times 60 min exposures with a 60 min interval) was studied. The magnetic effect was evaluated with respect to variations in the cell population density, mitotic activity and cytogenetic parameters. The experimental findings indicated that the magnetic fields of the above strength did not change significantly the rate of cell division and cell morphology neither did alter the genetic apparatus at the chromosomal level.
