Abstract

A study was made of the 0.5--24 hour effects of the stable magnetic field (SMF), with 9.9--42.4 kOe strength and 0.2--3.5 kOe/cm strength gradient, on the mitotic activity and bone marrow cell number in mice. Short-term treatments were shown to stimulate, and prolonged ones to inhibit mitotic activity, the degree of inhibition correlating with the strength and strenght gradient of SMF. The rate of mitotic index recovery was the smaller the longer the treatment and the higher the strength of SMF. With the most pronounced inhibition of the mitotic activity, the number of bone marrow cells was seen reduced. No increased frequency of aberrant mitoses in bone marrow cells has been noticed following the effect of SMF.

摘要

研究了强度为9.9 - 42.4 kOe、强度梯度为0.2 - 3.5 kOe/cm的稳恒磁场(SMF)对小鼠有丝分裂活性和骨髓细胞数量的0.5 - 24小时效应。结果表明,短期处理可刺激有丝分裂活性,而长期处理则抑制有丝分裂活性,抑制程度与SMF的强度和强度梯度相关。处理时间越长、SMF强度越高,有丝分裂指数恢复率越低。在有丝分裂活性受到最显著抑制时,可见骨髓细胞数量减少。在SMF作用后,未观察到骨髓细胞异常有丝分裂频率增加。
