[Pathomorphological reactions of the cerebral cortex nerve elements during treatment with an alternating magnetic field].

The results of investigations of certain aspects of the effect of magnetic fields on the nervous tissue are presented. The time course of pathomorphological reactions of the nerve cells and neuropile of the parietal cerebral cortex of rats receiving a single 61/2-hour treatment with alternating magnetic field (induction 20 mT, frequency 50 Hz) was studied. Changes in the microcirculatory bed of the cortex were observed manifested mainly by hydropic disorders in the cellular and fibrous components of the vessel wall. The effect of magnetic fields may be probably characterized by various hydropic changes in the cells, glial elements, and dendritic apparatus realized through disorders in the water-salt balance in cells.
