The aim of the research was evaluate the features of composition of fatty acids of lipid in plasma erythrocytes of blood in patients with pulmonary tuberculosis (in particular, caseous pneumonia).
The comparative analysis of the content of individual fatty acids and total level of saturated, unsaturated and polyunsaturated fatty acids in plasma and erythrocytes of blood in patients with caseous pneumonia (affected and not affected by the consequences of the Chernobyl accident) determines a greater sensitivity to the erythrocyte lipid peroxidation and indicates a possible better use of erythrocytes of blood for the study of lipid metabolism, determining the severity of disease and correction of treatment.
