Baseline data from the Gubbio Population Study in north central Italy were used to investigate the relation of hematocrit to blood pressure and hypertension among 2,809 men and women aged 25-74 years. Independent of gender, age, and other confounders, the hypertensive group had a higher hematocrit than the nonhypertensive group (p<0.001). In comparison with the untreated hypertensive group, the...

PURPOSE To evaluate the occurrence and time course of hem- and lymphangiogenesis after normal-risk corneal transplantation in the mouse model and to test whether pharmacologic strategies inhibiting both processes improve long-term graft survival. METHODS Normal-risk allogeneic (C57BL/6 to BALB/c) and syngeneic (BALB/c to BALB/c) corneal transplantations were performed and occurrence and time ...

BACKGROUND The Precision Xtra(®) meter is a promising low cost electrochemical point-of-care unit for measuring blood glucose concentration ([gluc]) in cattle blood. The meter uses an algorithm that assumes the intra-erythrocyte [gluc] equals the plasma [gluc] on a molal basis, and that the hematocrit is similar in humans and cattle. OBJECTIVES The primary objective was to determine the accur...

BACKGROUND In a whole blood coagulation test, the concentration of any in vitro diagnostic agent in plasma is dependent on the hematocrit level but its impact on the test result is unknown. OBJECTIVE The aim of this work was to clarify the effects of reagent concentration, particularly Ca2+, and to find a method for hematocrit estimation compatible with the coagulation test. METHODS Whole b...

Background: Preoperative hematocrit estimation has been one of the basic routine requirements before an anaesthetic is administered. Non availability of hematocrit result or a value less than 30% often led to cancellation of an elective surgery by the anaesthetist. Objective: The aim of the study was to determine the prevalence of anemia among adult patients presenting for day case surgery in t...

In the previous reports (Ishiguro 1961, Ishiguro et al. 1961) the author has pointed out that the pantothenic acid content in blood of rural inhabitants decreases with age, particularly in females. In the following study (Ishiguro 1962), the author reported that the blood pantothenic acid contents of pregnant women showed the level lower than that of non-pregnant women at the same age groups, a...

The paper is devoted to the comparison of different one-dimensional models blood flow. In such models, non-Newtonian property considered. It demonstrated that for large arteries, small parameter observed in and perturbation method can be used analytical solution. paper, simplified nonlinear problem semi-infinite vessel with constant properties solved analytically, solutions are compared. effect...

The optimum arterial perfusion pressure during cardiopulmonary bypass (CPB) remains uncertain. A correlation in some form with the patients' resting pressure almost certainly exists. Temperature and hematocrit affect blood viscosity. The optimum perfusion pressure during aortic surgery will vary after the initiation of CPB resulting cooling, heating, and hematocrit changes. Poiseuille's Law was...

CROWELL, JACK W., ROBERT G. FORD AND VIRGINIA M. LEWIS. Oxygen transport in hemorrhagic shock as a function of the hematocrit ratio. Am. J. Physiol. I g6(5) : I 033-1038. I g5g.-The oxygen consumption, arterial and venous oxygen concentration, and the arterial blood pH were measured, and the cardiac output, peripheral resistance and maximum oxygen transport capacity determined in 75 dogs with d...
