The objective of this study was to evaluate the relationship of whole blood viscosity and its major determinants (plasma fibrinogen level, hematocrit, hemoglobin and blood cell count) to advancing age. A total of 249 subjects (mean age 49.9+/-21.5; range 19-102 years) were included in the study. They were divided into three groups, (A) 60 years, n, 84.

Blood viscosity and blood pressure
Pathology, 1981The viscosity of blood from 214 men and 206 women visiting a health screening clinic was measured with a recently developed Sydney Hospital viscometer at shear rates 0.1, 1.0 and 100 sec-1. A significant positive correlation (P P >0.01, r = 0.15) at 0.1 sec-1. It is suggested that this sex-specificity may be related to that found by investigators who

Anomalous viscosity of human blood
American Journal of Physiology-Legacy Content, 1965The viscosity of human blood relative to distilled water observed in a capillary viscometer decreases with the length (in the range of 1.65– 10.5 cm) and increases with the reduction of the radius (in the range of .0106–.0217 cm) of the capillaries. No such changes are present when the flow rate of oils instead of water is used for the calculation of ...

An analyzer that determines blood viscosity at different shift speed has been designed. Its operation principle is based on the use of rotation viscosity measurement using a rotor freely floating in the sample. A blood sample is placed between the stationary thermostabilized measuring cylinder and a free floating rotor.

Whole blood viscosity in preeclampsia
American Journal of Obstetrics and Gynecology, 1982Whole blood viscosity was measured in 41 patients with preeclampsia and in 51 normotensive control subjects. The mean viscosity in the preeclamptic group had a highly significant elevation (t = 9.752, p less than 0.001, at a shear rate of 0.1 sec-1 and t = 4.223, p less than 0.001, at a shear rate of 100 sec-1).

Portal Hypertension and Blood Viscosity
Journal of Clinical Gastroenterology, 2007Previous studies, exploring the effect of blood viscosity on portal pressure in portal hypertensive humans and animal models, have shown conflicting results. In a series of studies, in portal vein constricted rats, we investigated effects of reduced blood viscosity on the hyperdynamic circulation, portal pressure, and vascular geometry.

When a fluid traverses a straight tube of sufficient length the individual molecular constituents arrange themselves eventually parallel to the long axis of the tube. Moreover, the cylinder of fluid does not move forward as one unit, but in such a manner that the central portion attains the greatest speed of flow, while the more external layers show a ...
