RHEOLOGICAL PROPERTIES OF ERYTHROCYTES AT HEALTHY CHILDREN OF A YOUNGER SCHOOL AGE

Abstract

It leaves no doubt that morphofunctional
features of a childs organism are in many respects defined
by the sufficient inflow of blood to the organs. The
aim of the paper is to investigate the condition of rheological
properties of erythrocytes at healthy children of
a younger school age. Under supervision there were 24
healthy children at the age of 7; 25 children at the age
of 8 and 26 children at the age of 9. In the circulation
of the blood of younger schoolboys with the increase
of age the tendency to the increase of the quantity of
reversible and irreversible changed forms of erythrocytes
at decrease of inactive forms is marked. Revealed
dynamics of the degree of deformation of erythrocytes
causes the increase of the units of red blood little bodies,
providing a certain level of rheological properties of
blood and the work of internal organs, necessary for the
growth and development of the organism in the absence
of the risk of the development of microthrombosis. Thus,
at 7-9-year-old children the tendency to the increase of
deformation changes and the strengthening of aggregative
activity of erythrocytes is marked.
