[Mitogenic effect and acceleration of stabilization process in the renal glomeruli of hypertrophied kidney after exposure to magnetic field].
Experiments designed to investigate the effects of magnetic fields of different nature, induction, exposure duration and multiplicity, have established a stimulating action of alternating magnetic field of 15 mT applied 2-5 times for 30 min daily on mitotic division of proximal tubule epitheliocytes. The degree of renal glomeruli capillary lumina distention (CLD), defined as the ratio of the total area of glomerular capillaries to glomerular area, was found to be variable, indicating the asynchronism of their filling with blood. Elevated filtration volume in a single kidney left after nephrectomy, was provided by a synchronization of blood filling of renal glomerular capillaries, that was manifested by the shift of their major part to the groups with high CLD and the appearance of glomeruli with extremely dilated capillaries. These changes were more significant and were detected earlier following exposure to alternating magnetic field.
