Phase transition temperatures of the water-rich part of the H 2 O-NaCl-HES ternary system have been studied by means of differential thermal analysis. The experimental data indicate that the protective action of the macromolecular agent HES is differ

The present study was carried out to investigate the influence of cryopreservation on human T-cell subsets defined by their membrane receptors for Fc IgM (TM) and Fc IgG (TG) and by their membrane antigens. For this purpose isolated T cells, obtained

An analysis of solute redistribution in binary aqueous salt solutions during unidirectional freezing with a planar solid-liquid interface is presented. A cryomicroscope was equipped with a specially designed freezing stage yielding a well-defined tem

Purified human granulocytes were frozen in isotonic saline at different constant cooling rates down to -60 degrees C and subsequently thawed on the thermally defined cryostage of a cryomicroscope. Cells monitored on videotape were examined with respe

A model is presented describing the transient freezing of a binary aqueous solution in a region of finite extent. The model consists of three partial differential equations that are coupled by common non-linear boundary conditions in analogy to simil

A better understanding of the freezing process in the extracellular suspension medium implies the consideration of deviations from equilibrium, i.e., unsteady diffusion of heat and mass with a moving phase boundary. Such phenomena, especially solute

This paper deals with the stability of planar phase boundaries during transient solidification of binary aqueous solutions and raises the question of the time and wavenumber characterizing t he breakdown of the phase boundaries in these solidificatio

Red blood cells were frozen in small capillaries down to −196 °C at different linear cooling rates with or without the cryoadditive HES; the thawing rate was 3000 or 6500 °C/min. Hematocrit and hydroxyethyl starch concentration varied independent
