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.

摘要

在持续15天暴露于1000奥斯特的恒定磁场中时,观察到角膜上皮和骨髓有丝分裂指数出现双相变化。该指数最初下降,随后恢复并出现超再生。组织中的细胞计数变化不显著,且在磁场关闭后迅速恢复正常。每天改变磁场方向相对于实验动物身体的位置,并未导致有丝分裂活性抑制增加;然而,适应性过程的有效性明显下降。这些暴露并未在受试组织细胞中诱发染色体畸变。
