Abstract

Correlation spectroscopy methods are widely used to study dynamical, morphological and optical parameters of biological objects. This work makes an attempt to explore these methods (in particular, due to their expressively) for diagnosing whole blood under normal and pathological states (cardiovascular diseases). Not only morphological characteristics of blood elements are known to change under diseases, but also its biochemical composition does. However, the biochemical analysis of blood is rather time and labor consuming. The paper is directed to investigate the correlation between optical characteristics of light scattering by blood and its biochemical parameters. Samples of whole blood were in vitro investigated for ills with different diagnoses and extend of cardio-vascular diseases as well as for essentially healthy donors. Simultaneous with the above characteristics we have monitored volumetric concentration of lipoproteides, erythrocytes and hemoglobin. The analysis of obtained results has show that the width of spectrum is greater for samples from healthy persons then from ills. Comparison of measured data on frequency spectrum, diffuse reflectivity's, biochemical and morphological blood parameters of the studied samples has shown the high correlation between the spectrum halfwidth and concentration of lipoproteides, erythrocyte setting rate. Some poorer correlation with spectrum occurs for concentration of hemoglobin and cholesterol. Thus, these are revealed an opportunity to design on express non-invasive method for determining the possibility of atherosclerotic disease.
