[Role of lipids in adaptive responses of the body to extreme exposure].
Experiments were conducted on 250 male albino rats to study the blood serum lipid spectrum in total-body dehydration, adrenalin-induced necroses of the myocardium, under the effect of transport noise with an equivalent level of 80-95 decibels and ultrashort-wave range electromagnetic field of 5-6 V/m intensity. In the early stages of exposure to the effect of extreme factors the change in lipid metabolism was monotypic in character and was manifested by hypercholesterolemia at the cost of the free fraction, increase of the level of triglycerides, free fatty acids and activity of lecithin-cholesterol acyltransferase, and reduction of the content of total phospholipids and disorders of their composition. These changes are associated with disturbed neurohumoral regulation and reflect the unspecific response of the organism to damage in the form of mobilization of lipids from the depot and switching metabolism from the carbohydrate to the lipid type.
