Erythrocyte membrane permeability coefficients have been determined for a series of amides by a method based on the physical and mathematical modelling of hypotonic haemolysis process. The results show that penetration of the substances occurs by two alternative ways through aqueous pores formed by proteins and by the direct dissolving of the molecules in(More)
Erythrocyte membrane permeability coefficients for a series of diols have been defined by the method developed. The method is based on the physical and mathematical modeling of hypotonic hemolysis process. There have been also determined membrane permeability coefficients for erythrocytes treated with p-chloromercuribenzenesulfonic acid monosodium salt(More)
The densities of cell distributions by spherical index (SI) in erythrocyte populations from healthy adults and donors with endocrine pathologies were determined via the developed method. The investigation shows that this characteristic varies for different donors, thereby reflecting the erythrocyte population state of an individual donor. Individual(More)
Background and Purpose: Diseases caused by bacterial pathogens are the result of the host-pathogen interaction, therefore the contact of bacteria with erythrocytes is highly possible. The aim of this work was to study Streptococcus thermophilus adhesion on human erythrocytes depending on the various pH and ionic strength of the medium. Materials and(More)
Permeability coefficients of rat and rabbit erythrocyte membranes for a series of amides, as well as for erythrocytes treated with p-chloromercuribenzenesulfonic acid monosodium salt (pCMBS) have been determined at 25 and 37 degrees C. Directly proportional dependence of the pCMBS treated erythrocyte permeability for investigated substances and their(More)
BACKGROUND Maintaining cell surface properties after freezing and thawing, characterized in particular by the surface potential and associated with it cell ability to intercellular adhesion, could be used as a characteristic of successful cryopreservation. OBJECTIVE This study was conducted to research applying different erythrocytes freezing modes and(More)
