Rheologic properties of erythrocytes and activities of their Ca(2+)-ATPase and Na+, K(+)-ATPase were analyzed together with standard erythrocyte values in seven mammalian species (man, rat, mouse, rabbit, hamster, guinea pig and dog). The number of erythrocytes in the blood of animals investigated correlated inversely with the mean cell volume (MCV) (r =… (More)
We developed a method for evaluation of membrane permeability for water based on the analysis of osmotic permeability profiles of red blood cells. Deformability of completely spherulated erythrocytes changed in a dose-dependent manner during formation of artificial water pores (by nystatin) and blocking (by HgCl2) of the existing ones.
In experiments on Wistar rats and guinea pigs, dynamics of blood hematological parameters and of erythrocyte deformability index (DI) was studied from birth to the 3-month age. In rats, significant changes were revealed in the picture of blood for the first month of postnatal ontogenesis. The number of erythrocytes and leukocytes sharply increased, the… (More)
The comparative studies of rheologic properties of the blood from mammals, which was carded out earlier, using rheometric and filtration methods, have shown a very poor elasticity of the red blood cell membranes in some cattle species and especially in sheep [1-3]. The reasons for this phenomenon have not been elucidated. Since the ektacytometric method had… (More)
