title: [Effect on mitotic activity of prolonged exposure to constant and alternating 1000 oersted magnetic fields].
abstract: During a prolonged (15 days) exposure to a constant magnetic field of 1000 oersted two-phasic changes in the mitotic index of the corneal epithelium and bone marrow were noted. The initial decrease of the index was replaced with its recovery and hyperregeneration. The cell count of the tissues varied insignificantly and rapidly returned to normal when the field was switched off. The every day change in the field direction with respect to the body position of the test animals induced no increase in the inhibition of the mitotic activity; however, the effectiveness of adaptive processes declined noticeably. These exposures did not induce chromosome aberrations in the cells of the tested tissues.
