[Effect of an alternating magnetic field of industrial frequency on the lipid composition of the rat liver]. 1987

O N Chernysheva

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.

UI	MeSH Term	Description	Entries
D008055	Lipids	A generic term for fats and lipoids, the alcohol-ether-soluble constituents of protoplasm, which are insoluble in water. They comprise the fats, fatty oils, essential oils, waxes, phospholipids, glycolipids, sulfolipids, aminolipids, chromolipids (lipochromes), and fatty acids.

D008099	Liver	A large lobed glandular organ in the abdomen of vertebrates that is responsible for detoxification, metabolism, synthesis and storage of various substances.	Livers
D008297	Male		Males
D008930	Mitochondria, Liver	Mitochondria in hepatocytes. As in all mitochondria, there are an outer membrane and an inner membrane, together creating two separate mitochondrial compartments: the internal matrix space and a much narrower intermembrane space. In the liver mitochondrion, an estimated 67% of the total mitochondrial proteins is located in the matrix.

D010743	Phospholipids	Lipids containing one or more phosphate groups, particularly those derived from either glycerol (phosphoglycerides see GLYCEROPHOSPHOLIPIDS) or sphingosine (SPHINGOLIPIDS). They are polar lipids that are of great importance for the structure and function of cell membranes and are the most abundant of membrane lipids, although not stored in large amounts in the system.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
