The annual cycle of small ground squirrels (Spermophilus pygmaeus) consists of 2 periods: wakefulness (spring-autumn) and hibernation (winter). During the active period, ground squirrels breed (spring), accumulate fat reserves (summer) and prepare for hibernation (autumn). We suppose that the rheological properties of blood and the deformability of erythrocytes can change in different seasons of the animal's wakefulness period to adequately provide tissues with oxygen.

It was shown that after administration of physiological saline and after each session of ozone therapy occurs reduction of minimum aggregates strength and rate of spontaneous aggregation like and microviscosity and increase of deformability and water permeability of erythrocyte membranes. Dynamics of changes in the studied parameters of erythrocytes shows the improvement of the rheological properties of blood in patients not only immediately after the procedure, but and after update of blood in 2 weeks, 1 and 2 months after the course.

Variability of deformation and aggregation properties of erythrocytes is a component part of nonspecific antihypoxic response of formation of adequate blood flow in the tissues and efficiency of the microcirculation in different sections of the vascular bed. Degree of change in these properties during neonatal adaptation to spontaneous breathing can be a marker of its abnormality. We examined 19 healthy full-term newborns in the first 1-2 and 13 children in the first 5-7 days of life.

Mean erythrocyte volume of newborns more than in adults. Significant difference index of osmotic fragility of neonates were observed in the transition from swelling to hemolysis.

Purpose of the work was to explore likelihood of impairment of erythrocytes deformation and aggregation properties in a compensated magnetic field of the Earth. It was shown that complete magnetic deprivation does not alter rat's hemorheology substantially. Stress-related changes were found neither in blood nor adrenals of the animals.
