ABSTRACT The aim of the present study is comparison of changes of principal hemorheological factors responsible for blood flow disorders in the microcirculation in patients with ischemic brain infarcts. It was found that in venous blood samples the erythrocyte aggregability (examined with a direct, highly sensitive, quantitative technique) was considerably more increased (by mean of 120%) than the blood plasma fibrinogen contents, blood plasma viscosity, and hematocrit which increased only by 23.7%, 7.4% and 3.6%, respectively, as compared to the same hemorheological factors in the healthy controls.

Abstract

 

 

[su_animate type=”tada”]

The aim of the present study was the comparative analysis of the role of specific hemorheological derangements in the pathogenesis of ischemic brain infarcts with and without diabetes mellitus. Blood plasma viscosity, as well as red blood cells (RBC) aggregability were quantitatively investigated in all patients during the study. Both of the above mentioned indices of hemorheological disorders were significantly higher in the patients with brain infarcts and diabetes mellitus as compared to the control and the group of ischemic brain infarcts without diabetes.[/su_animate]

The aim of our work was a red blood cell deformation (rheological rheological ) at rheological degrees of severity of experimental hemorrhagic shock. The study of erythrocyte deformability violation and a compulsory monitoring of this physical value deserve more attention of fundamental and applied sciences. The modeling of hemorrhagic shock of different stages was performed in the group of anesthetized animals by means of standard blood discharge from the femoral artery (2,5 ml – first stage of shock; 5 ml – second stage of shock; 5ml – third stage of shock, n=12).[/su_animate]
