Abstract :
In this paper, the mathematical model for a lipid being in the liquid-crystalline phase is proposed. The temperature dependence of a free energy and the lipid order parameter was obtained. Formulas for the lipid dielectric anisotropy and for the order parameter determination in vivo by means of the anisotropy coefficient measurement by the method of reflectometry in mm-range were derived. The developed method of mm-range differential reflectometry makes it possible that electromagnetic waves, permeating the surface skin layers and reflecting from the surface of vessels may carry information about phase states of the lipids in the blood plasma. The results of the work can use in biological and medical researches and also in medical practice for the noninvasive diagnostics
