Evaluation of a Stroma-free Hemoglobin Solution for Use as a Plasma Expander
The preparation of large quantities of a stable, stroma-free hemoglobin solution without coagulant activity is described. Following infusion of this solution into phlebotomized dogs, there is no methemoglobin formation, no adverse effects on vital signs, and no demonstrable activation of blood coagulation. The hemoglobin maintains its oxygen-carrying capacity and liberates oxygen into tissues. ...
متن کاملPolyvinylpyrrolidone: the electromigration characteristics of the blood plasma expander.
Before the metabolic role of the blood plasma expander, polyvinylpyrrolidone (PVP) can be studied by the technic of ionography, some fundamental ionographic characteristics of the polymer, per se, must be determined. This study is concerned with the influence of such variable factors as time, potential gradient, temperature, the pH of the buffer and its ionic strength on the mobility of the mig...
متن کاملThe Use of an Ejector as a Refrigerant Expander
One of the thermodynamic losses in the vapor-compression retr1geration cycle is the throttllng process in the expansion valve. It work is extracted from the refr1gerant during the expansion process, the efficiency of the cycle is swnificantly 1mproved. It 1s proposed that the high-pressure retngerant be used as the motive fluid of a Jet ejector. Instead of extract1ng mechanical work from the ex...
متن کاملSuperior plasma retention of a cross-linked human serum albumin dimer in nephrotic rats as a new type of plasma expander.
Human serum albumin (HSA) is used clinically as a plasma expander in patients with hypoalbuminemia and can also function as a drug carrier. However, the administered HSA is readily eliminated from the blood circulation under pathological conditions, especially the nephrotic syndrome. In this study, we present data on the pharmacokinetics of a structurally defined HSA dimer [two HSA molecules th...
متن کاملAlginate plasma expander maintains perfusion and plasma viscosity during extreme hemodilution.
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,...
