Equal weights of the various protein fractions in plasma affect the plasma specific gravity equally, whereas weight for weight the fractions exert differing influences on the plasma viscosity. Thus fibrinogen has a greater effect on the plasma viscosity than does globulin, which, in turn, has a greater effect than albumin (Bircher, 1921 ; Naegeli, 1931; Oberst, 1939; Cowan and Harkness, 1947). ...

Dietary fiber may contribute to satiety. This study examined the effect of two dietary fiber characteristics, small intestinal contents viscosity and large intestinal fermentability, on satiety-and adiposity-related hormones in rats. Diets contained fiber sources that were non-viscous, somewhat viscous, or highly viscous, and either highly fermentable or non-fermentable, in a 2 × 3 factorial de...

AIMS To determine whether in Trichuris trichiura dysentery there is (1) evidence of a systemic inflammatory response, (2) evidence that the plasma protein disturbance has special characteristics compared with uninfected children in the endemic environment. METHODS Three groups of children (age 1.6 to 11.4 years) were studied: 53 cases of trichuris dysentery syndrome (TDS), 16 cases of chronic...

Plasma viscosity, photometric erythrocyte aggregation index, and erythrocyte filterability were measured in 194 patients with coronary artery disease. Patients with unstable angina (n = 64) had a higher plasma viscosity and photometric erythrocyte aggregation index than patients with stable angina (95% confidence intervals for the mean difference: 0.052-0.100 mPa.s for plasma viscosity, and 43%...

BACKGROUND Increased blood and plasma viscosity, hematocrit, fibrinogen, and activation of coagulation and leukocytes have been reported in patients with claudication; however, their associations with symptomatic and asymptomatic peripheral arterial disease have not been reported in an epidemiological study. METHODS AND RESULTS Blood and plasma viscosity, hematocrit, fibrinogen, urinary fibri...

In order to assess the relationships of erythrocyte sedimentation rates (ESR) and various acute phase reactants in diagnosing and following the remissions and exacerbations of various chronic diseases, multiple tests were performed on patients for whom an ESR was ordered. The Wintrobe and Westergren ESR, plasma and serum viscosity, hemoglobin, blood cell indices, fibrinogen, serum protein elect...

The present study was designed to determine the effects of hemodilution with gelatine (GEL) and hydroxyethyl starch (HES) on hematocrit, blood viscosity, systemic hemodynamics, and central retinal arterial blood flow in anaesthetized pigs. 20 pigs were studied. Hypervolemic hemodilution was induced by 30 ml kg-1h-1 GEL (n=10) or HES (n=10) infused over 30 min. The hematocrit decreased comparabl...

Endothelial function is modulated by wall shear stress acting on the vessel wall, which is determined by fluid velocity and the local viscosity near the vessel wall. Red blood cell (RBC) aggregation may affect the local viscosity by favoring axial migration. The aim of this study was to investigate the role of RBC aggregation, with or without altered plasma viscosity, in the mechanically induce...

BACKGROUND AND OBJECTIVES Increased vascular wall shear stress by elevated plasma viscosity significantly enhances the endothelial nitric oxide synthase (eNOS) activity during an acute isovolemic hemodilution. Also the modulation of plasma viscosity has effects on the cardiac function that were revealed if a left ventricular (LV) pressure-volume (PV) measurement was used. The aim of this study ...

Sex variations in some haemorheological parameters: Haematocrit (Hct), Erythrocyte Sedimentation Rate (ESR), Hemoglobin concentration (Hbc), Fibrinogen concentration (FC), Relative Plasma Viscosity (RPV) and Whole Blood Relative Viscosity (WBRV) were determined in 30 male and 20 female hypertensive subjects without complications, aged between 30 and 70 years. 30 male and 20 female normotensive ...
