RHEOLOGICAL PROPERTIES OF ERYTHROCYTES AT HEALTHY CHILDREN OF A PRE-SCHOOL AGE

Abstract

Erythrocytes define fluidity of blood in the
vasculars, limiting the level of the delivery of necessary
quantity of oxygen and nutrition to the tissue on which
the growth and the development of a child depends. The
purpose of the work is to investigate the condition of
rheological properties of erythrocytes at healthy children
of a pre-school age. There were healthy children a
pre-school age under supervision: 29 persons at the age
of 3; 27 persons at the age of 4; 26 persons at the age
of 5 and 25 persons at the age of 6 from safe families.
In the circulation of the blood at children under school
age the tendency to quantity increase of reversible and
irreversible forms of erythrocytes at decrease of inactive
forms is marked. Revealed dynamics of the degree
of the deformation of erythrocytes causes the increase
of the development 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 the development of an organism. Thus,
at 3-6 year-old children the tendency to decrease the
changes of deformation and to strengthen aggregative
activity of erythrocytes is marked
