Temperature and osmotic sensitivity of red blood cells of different mammalian species
N. M. Shpakova
There was performed a comparative study of red blood cells of different mammalian species (human, equine, bovine, canine) to the changes of osmotic and temperature environmental conditions. At 37 ?C a high sensitivity to the action of 4,0 Ì NaCl is characteristic for human and bovine cells, for human and canine ones at 0 ?C. Human and equine erythrocytes are easily damaged under hypotonic stress conditions at 37 and 0 °Ñ, but they are enough stable to the action of hypertonic medium (4,0 Ì NaCl, 0 Ñ). Under cold shock the highest resistance is found for bovine erythrocytes. The findings are discussed with basing on structural and functional peculiarities of erythrocytes of different mammalian species.
