Vibration effects on fatty acid composition of organ and cell membrane lipids. 1991

Institute of Hygiene and Occupational Health, Medical Academy, Sofia, Bulgaria.

The influence of middle and high frequency vibrations (50 and 150 Hz) on the fatty acid pattern of structural lipids in white rat liver, kidney, heart, aorta and muscular tissue was studied in a 3-month experiment. The study also examined the fatty acid composition of phospholipids in erythrocyte cell membranes of workers occupationally exposed to vibrations and of patients suffering from vibration disease. Statistically significant changes in the per cent distribution of fatty acids were observed, which were more evident in the liver and kidney of experimental animals, and also after high frequency (150 Hz) vibration exposure. Changes in human subjects were greater in workers exposed to hand-arm vibrations and in patients suffering from vibration disease. Routine and more precise methods are needed to assess occupational risk via determination of the lipid metabolism state in workers exposed to vibrations and in patients suffering from vibration disease.

UI	MeSH Term	Description	Entries
D008297	Male		Males
D008563	Membrane Lipids	Lipids, predominantly phospholipids, cholesterol and small amounts of glycolipids found in membranes including cellular and intracellular membranes. These lipids may be arranged in bilayers in the membranes with integral proteins between the layers and peripheral proteins attached to the outside. Membrane lipids are required for active transport, several enzymatic activities and membrane formation.

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.	Phosphatides,Phospholipid
D002849	Chromatography, Gas	Fractionation of a vaporized sample as a consequence of partition between a mobile gaseous phase and a stationary phase held in a column. Two types are gas-solid chromatography, where the fixed phase is a solid, and gas-liquid, in which the stationary phase is a nonvolatile liquid supported on an inert solid matrix.

D005227	Fatty Acids	Organic, monobasic acids derived from hydrocarbons by the equivalent of oxidation of a methyl group to an alcohol, aldehyde, and then acid. Fatty acids are saturated and unsaturated (FATTY ACIDS, UNSATURATED).

D000328	Adult	A person having attained full growth or maturity. Adults are of 19 through 44 years of age. For a person between 19 and 24 years of age, YOUNG ADULT is available.	Adults
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.
