[Effect of an alternating magnetic field of industrial frequency on the lipid composition of the rat liver].

Multiple application (15 runs for 5 hours a day) of an alternative magnetic field of industrial frequency causes changes in lipid spectrum and phospholipid fractional composition of mitochondria and postmitochondrial fraction in rat liver. A decrease in the level of free fatty acids, triglycerides and cholesterol esters in mitochondria is registered, which presumably indicates an increase of the fats use in the cell's energetics. Changes in the phospholipid composition of mitochondria are negligible. In contrast to mitochondria, accumulation of lipids--triglycerides, cholesterol and its esters against a background of disbalance in phospholipid composition is established, which may presumably be one of the reasons for development of destructive infringements in the liver parenchyma during application of the alternating magnetic field.
