Magnetotherapy in clinical and ambulatory practice
The results of experimental research into the physical, physiological and biological effects on the tissues of electromagnetic fields are analysed. The research was conducted on 354 patients either hospitalised or treated in outpatients departments for orthopaedic conditions. These patients were treated with electromagnetic currents for a period of 10 days and the effects mainly on oedema, pain and inflammation were evaluated. The effects were distinctly positive especially in the case of acute lesions. In addition, no unpleasant or harmful topical or systemic side effects were observed.

Electroendocytosis: exposure of cells to pulsed low electric fields (PEMF) enhances adsorption and uptake of macromolecules
This study demonstrates alteration of cell surface, leading to enhanced adsorption of macromolecules (bovine serum albumin (BSA), dextran, and DNA), after the exposure of cells to unipolar pulsed low electric fields (LEF). Modification of the adsorptive properties of the cell membrane also stems from the observation of LEF-induced cell-cell aggregation. Analysis of the adsorption isotherms of BSA-fluorescein isothiocyanate (FITC) to the surface of COS 5-7 cells reveals that the stimulated adsorption can be attributed to LEF-induced increase in the capacity of both specific and nonspecific binding. The enhanced adsorption was consequently followed by increased uptake. At 20 V/cm the maximal binding and subsequent uptake of BSA-FITC attached to specific sites are 6.5- and 7.4-fold higher than in controls, respectively. The nonspecific LEF-induced binding and uptake of BSA are 34- and 5.2-fold higher than in controls. LEF-enhanced adsorption is a temperature-independent process, whereas LEF-induced uptake is a temperature-dependent one that is abolished at 4 degrees C. The stimulation of adsorption and uptake is reversible, revealing similar decay kinetics at room temperature. It is suggested that electrophoretic segregation of charged components in the outer leaflet of the cell membrane is responsible for both enhanced adsorption and stimulated uptake via changes of the membrane elastic properties that enhance budding and fission processes.

Effect of infrared radiation and combination of it with constant and alternating magnetic fields (PEMF) on the recuperative processes in the thymus, liver, and blood of stressed rats
Changes in thymic cells activity in stressed animals were compared to the level of 11-oxycorticosteroids in the blood and antioxidant hepatic activity in exposure of the hepatic projection region and solar plexus to varying doses of infrared radiation and its combination with constant or alternating magnetic fields. It was shown that combined action of constant or variable (pulsed with negative semiperiods) magnetic fields and infrared radiation in the above exposure promotes optimal conditions for regeneration in stressed rats.
