[Effect of decreasing hydrodynamic resistance of a polymer on localization of sclerotic plaques. A model study].

Flow structure and wall shear stress and the changes in these parameters induced by the administration of a drag-reducing polymer polyethylene oxide WSR-301 at a concentration of 10(-5) g/ml were studied in a glass tube with a T-junction by the laser Doppler anemometry technique. The pattern of wall shear stresses is in a good agreement with the data, obtained for rabbits in [1]. For tubes with rigid walls, the location of plaques corresponds to regions of a high wall shear stress.

[New findings concerning pathogenesis of disorders of cerebral circulation].

The data about the role of blood flow in atherosclerosis development were examined. The aim of the study was determination of hydrodynamic blood resistance and Toms effect in patients with ischemic disorders of cerebral circulation in different periods of the disease. 45 patients with atherosclerotic damages of major arteries of head were observed.
