The rates of washout of 133Xe and 131I-iodoantipyrine from the myocardium into the coronary sinus blood were determined over a wide range of hematocrits after simultaneous injection of the isotopes into the left anterior descending coronary artery of dogs. The ratio of the monoexponential disappearance constants (kX/kI), which is a measure of the ratio of the dynamic blood-tissue partition coef...

Objective: Blood is a body fluid that plays role in transporting oxygen, nutrients, metabolic waste, and serves as component of the immune system. Its measurable indices such hematological profile affected by food consumed. This study aimed to examine linseed use complete feed on hematology value sheep blood. Methods: research was conducted at “Mitra Karya Farm” Purworejo Village, Gemolong Dist...

The aggregation, dispersion and deformation of cellular components of blood in the vasculature affect blood rheology to a greater extent. At low shear rate erythrocytes tend to aggregate and form rouleaux and at a high shear rate they dis perse and get deformed into ellipsoid with their long axis aligned in the flow direction. While rouleaux formations increase viscosity, dispersion and deforma...

Because of complicated rheological issues related with sickle cell blood, there exists a practical need to rationally determine critical hematocrit in transfusions for sickle cell patients. In this research, two major effects, i.e. oxygen concentration and hematocrit, are considered in a theoretical hydrodynamic model incorporating oxygen transport and lubrication theory. The pressure drop depe...

OBJECTIVE "Reference ranges" are developed when it is impossible or inappropriate to establish "normal ranges" by drawing blood on healthy normal volunteers. Reference ranges for the hematocrit and the blood hemoglobin concentration of newborn infants have previously been reported from relatively small sample sizes by using measurement methods that now are considered outmoded. METHODS We soug...

A comparison of 60 blood transfused and 71 nonblood transfused hepatic resection patients was done to evaluate strategies for reducing blood transfusions during hepatic surgery. There were no significant differences between the two groups with regard to preoperative laboratory data, except for prothrombin time and hematocrit value. The mean operative blood loss was 1990 ml and 760 ml in the blo...

INTRODUCTION Measurement and monitoring of blood glucose levels in hospitalized patients with portable glucose meters (PGMs) is performed widely and is an essential part of diabetes monitoring, despite the increasing evidence of several interferences which can negatively bias the accuracy of measurements. The purpose of this study was to evaluate the effect of the hematocrit on the analytical p...

This paper discusses a current misinterpretation between different parameters of hemoglobin concentration measurement and its amplification under conditions of blood loss. The paper details the distinction between microcirculatory hematocrit and the hematocrit of the macrocirculation to analyze clinical use of real-time patient hemoglobin concentration measurement by noninvasive point-of-care d...

abstract this investigation was conducted to replace artificial food with gammarus and study this effect on survival and growth parameters of jewel in case of completely randomized design with 3 treatments and 3 replicates in each treatments. 270 jewel fishes with initial mean weight of 1.22±0.72 were reared in 9 aquariums (30 fishes in each aquarium) with volume of 100 liter water. experimenta...
