[Relationship between lipid peroxidation processes, blood vessel wall changes and properties of erythrocytes in pathogenesis of microhemocirculation disorders during experimental diabetes mellitus].
The microhemocirculation play the main role in the development of the micro-and macroangiopathy during Diabetes Mellitus. The aim of our work was to study changes of free-radicals and deformability of erythrocytes using the filtration-photometric and electronic-paramagnetic methods in white rats during Alloxan Diabetes at different stages. Erythrocytes deformability was estimated by the time needed for erythrocytes passage through the filter and state of blood and blood vessels walls were studied by the EPR method. It had been detected that erythrocytes deformability sharply reduced and blood vessels wall was damaged by activation of lipid peroxidation and inhibition of antioxidant system, which may lead to disorders of microhemocirculation.
