BACKGROUND Increased level of blood viscosity, which is one of the major factors that determine blood rheology, has been reported as a risk factor or predictor for cerebrovascular events. We investigated how blood viscosity is associated with acute stroke and chronic radiological manifestations of cerebral small vessel disease, and how blood viscosity changes after stroke. METHODS We prospect...

Extreme hemodilution was performed in the hamster chamber window model using 6% Dextran 70, lowering systemic hematocrit by 60%. Animals were subsequently divided into three groups and hemodiluted to a hematocrit of 11% using 6% Dextran 70, 6% Dextran 500, and a 4% Dextran 70 + 0.7% alginate solution (n = 6 each group). Final plasma viscosities were 1.4 +/- 0.2, 2.2 +/- 0.1, and 2.7 +/- 0.2 cp,...

Erythrocytes and plasma proteins contribrelated (p < 0.001) with the plasma ute to viscosity of blood. Therefore, blood macroglobulin concentration in g/100 ml. viscosity was measured in 16 persons with The plasma of patients with macroglobumacroglobulinemia with a cone-plate vislinemia is a non-Newtonian fluid, but at a cometer at defined shear rates. In each given shear rate the plasma viscos...

The objective of this study was to investigate the effects of feeding electron irradiated flaxseed (FS) on performance, carcass characteristics, blood parameters, digesta viscosity, and nutrient digestibility in broiler chickens. In a 2 × 2 factorial arrangement, 320 day-old broiler chicks were randomly assigned to one of five experimental diets, each with four replicates containing 16 chicks e...

Regional cerebral blood flow measurements and neuropsychological testing were conducted before and after venesection on 6 patients with polycythemia secondary to chronic obstructive pulmonary disease. Venesection resulted in lowered viscosity and hematocrit, and an accompanying improvement in cerebral perfusion and mental function. Blood flow was significantly increased in the left cerebral hem...

BACKGROUND & OBJECTIVES The antimalarial combination drug artemether/lumefantrine has been shown to be effective against malaria parasite through its haemolytic action. This drug is sometimes co-administered with vitamin C in patients with malaria. Vitamin C is associated with antioxidant properties which would be expected to protect against haemolytic effects of this antimalarial drug. This st...

OBJECTIVE To investigate haemorheological changes during pregnancy in a Latin American population and compare to previously published data from Caucasian populations. DESIGN Cross-sectional study. POPULATION 75 pregnant women at 10-36 wk of gestation and 17 non-pregnant female controls in Lima, Peru. All the women and their ancestors for three generations were born and lived at sea level. ...

In conventional cold-storage organ preservation, the donor organ is flushed with University of Wisconsin (UW) solution at 0-4 degrees C. The initial flush is used to wash out blood from the microcirculation to allow optimal preservation with the UW solution. The component hydroxyethyl starch (HES) of UW is known to cause relatively high viscosity and a possible interaction with blood, i.e. incr...
