Spectral analysis of time functions of plasma glucose and immunoreactive insulin during intravenous glucose tolerance testing on atherosclerosis and noninsulin-dependent diabetes mellitus

摘要

Abstract: The time functions of plasma glucose and insulin obtained during intravenous glucose tolerance test were approximated by sections of Fourier series. The convincing quantitative and quality distinctions of amplitudes both phases of the first and second harmonics of decomposition of the indicated time functions are obtained. These distinctions were used as a basis of diagnostic algorithm of metabolic violations appropriate for atherosclerosis and non-insulin dependent diabetes mellitus in clinically obvious and preclinical stages. !8
