[Assessment of an association between fatty acid structure of lipids in pulmonary surfactant and 137Cs content in the body of children, residents of radiation-contaminated areas].

: An evaluation of correlation between fatty acid composition in pulmonary surfactant lipids and 137Cs content in the body of children, residents of radiation-contaminated areas revealed that a increased incorporation of 137Cs promotes a disruption of fatty acid balance towards an increase in the saturation of the surfactant lipid complex, a destruction of lecithin fraction of surfactant, a decrease in antioxidant properties of surfactant system, an activation of lipid peroxidation processes in the respiratory area of lung by lipoxygenase type, a disturbance of polyunsaturated fatty acid metabolism on the stage of bioregulators-eicosanoid formation.
