The aim of this study was to assess the level of damage to mammalian erythrocytes under post-hypertonic shock depending on the concentration of NaCl in the dehydration medium and to determine the effect of hypertonic NaCl solutions on the condition of mammalian erythrocytes by flow cytometry. To achieve this goal, spectrophotometric and cytometry research methods were used. The data obtained showed that post-hypertonic lysis of mammalian erythrocytes depends on the concentration of NaCl in the dehydration medium. The most sensitive to the effects of post-hypertonic shock are rat erythrocytes, the least sensitive are rabbit cells. Cytometry studies revealed significant changes in the histograms of the distribution of erythrocytes of all mammalian species with increasing salt concentration in the dehydration medium. These changes are species-specific and are probably related to changes in cell volume and morphology. The data revealed a relationship between the level of post-hypertonic hemolysis and the values of such indicators as the median distribution and the coefficient of variation. Thus, an increase in the sensitivity of mammalian erythrocytes to post-hypertonic shock with increasing salt concentration in dehydration medium was usually accompanied by a decrease in the median cell division, and higher values of the coefficient of variation are characteristic of mammalian erythrocytes resistant to post-hypertonic shock.

Key words: mammalian erythrocytes, dehydration, post-hypertonic shock, cytometry, median, coefficient of variation, distribution
