ABSTRACT
BACKGROUND:
One of the key elements of successful transplantation is effectively rinsing off the blood and preserving organs under controlled hypothermia. The aim of the study was to analyze the physicochemical parameters of Biolasol (Biochefa, Sosnowiec, Poland) and histidine-tryptophan-ketoglutarate (HTK) (Custodiol) solutions, which are recommended for perfusion and preservation of abdominal parenchymal organs.METHODS:
Biolasol and HTK solution were used for the study. The solutions were subjected to physicochemical analysis involving pH, density, osmolarity, viscosity, refractive index, zeta potential, hydrodynamic diameter, and rheological properties. Rheological parameters were associated with morphologic features of fluids.RESULTS:
HTK and Biolasol are non-Newtonian systems with pseudoplastic properties and yield stress. The solutions begin to flow under shear stress greater than the ultimate stress. In addition, a nonlinear relationship of their viscosity as a function of velocity gradient (shear rate) was observed.CONCLUSIONS:
The solutions reproduce blood properties, which leads to the conclusion about their effective filling of the vascular bed and high efficiency in organ rinsing.
