title: [New method for diagnosis of lipid metabolic disturbances].
abstract: A new analytical procedure for determining the fraction composition (FC) of lipoproteins (LP) is developed on the basis of the physical method small-angle X-ray scattering (SAXS). This method quantitatively determines the levels of the basic fractions of LP and their subfractions in plasma or serum to analyze LP FC and to diagnose lipid metabolic disturbances. The results obtained by this procedure were compared with those of gel-electrophoresis, biochemistry, and medical diagnosis. There was a good agreement of SAXS and routine methods. The new procedure shows extremely rapid (1.0-1.5 hr) analysis, uses a single reagent (such as the saccharose type), has a high accuracy, and resolution. The analysis requires as high as 0.05 ml of plasma or serum. LP FC may be analyzed both in protein-free and whole native plasma and sera. The findings may be used in clinical care for diagnosis of dyslipidemias and for researches.
