[Tissue specificity of changes in mitotic activity induced by strong magnetic fields].

The mitotic index, frequency of chromosomal aberrations, and the cell count in the bone marrow, corneal and intestinal epithelium of mice exposed for one hour to a magnetic field (MF) with a period of 30 sec and intensity of 2.9-127 kOe have been examined. The mitotic activity of the corneal epithelium was inhibited during the exposure, and began to recover immediately after its terminations.

[Effect of strong, infralow-frequency magnetic fields on bone marrow cell division].

The effect of an infralow frequency magnetic field of 3-127 kOe applied for 1 hr on mitotic activity, frequency of chromosomal aberrations and number of bone marrow cells of mice was studed. The exposure of mice to fields of 3 and 8 kOe stimulated and to fields of 54 and 127 kOe inhibited mitotic activity. No increase in the frequency of aberrant mitoses in bone marrow cells was noted.
