[Status of the lipid phase of plasma membranes of the rat heart after repeated exposure to an alternate magnetic field of 50 Hz frequency].
The concentration of lipids and spectrum of phospholipids in plasma membranes of hearts of rats exposed for 15 times to intermittent (1:2) alternative magnetic field of 50 Hz and 9.4 mT were measured. This exposure lead to accumulation of lipids and increase of free fatty acids, triacylglycerides, cholesterol esters and phospholipids (although to a smaller extent). The cholesterol/phospholipids ratio decreased significantly. The spectrum of phospholipids was similar to that in the controls, except for phosphatidyl inositol whose content grew.
