Hemorheological characteristics of blood in various diseases: Diabetes mellitus,hypertension,acute infection,ischaemic heart disease & attempted suicide 1

Abstract

The hemorheological characteristics of the blood samples, obtained by venepuncture from various groups of patients, are determined. Shear stress-shear rate relationship were determined by capillary viscometer at various shear rates ranging from 1 sec⁻¹ to 30 sec⁻¹. Erythrocyte sedimentation rate (ESR) was determined by Westergren method. The results indicate that at constant hematocrit, the slope of the line representing shear stress-shear rate relationship, and ESR of blood samples change, depending on the clinical conditions of the individuals. For various values of the hematocrits, the variation of the above mentioned parameters along with fibrinogen level & blood viscosity, in various diseases are given.
