Abstract


Morphofunctional peculiarities of child's organism are determined to a large extent by the adequate supply of blood to the organs. The aim of this work is to explore the status of rheological properties of erythrocytes and platelets from healthy children of primary school age. The work was done on the basis of data of 24 healthy 7 year-olds, 25 - 8 year-olds and 26 children of 9 years of age. It was found that the older is the child, the higher is the number of deformed erythrocytes and platelets in his bloodstream, and the fewer is the number of diskocytes. The revealed dynamics of cytoarchitecture of erythrocytes and platelets causes the increase of their aggregation, providing a certain level of rheological properties of blood and perfusion of internal organs. This level is necessary for the organism's growth and development when there is no risk of micro-trombus formation.

Key words


rheological properties of blood, children, junior school age, erythrocytes, platelets, cytoarchitecture, aggregation
