MORPHOLOGY OF INTRAVASCULAR AUTOROSETTES AT HEALTHY CHILDREN

Abstract

The purpose of the study was to evaluate the morphological types of autorotation (AR) in the peripheric blood in children under the influence of outdoor air pollution. Material and methods. 613 students of I-II health groups under ordinary life conditions were surveyed. They were divided into 2 groups depending on the index of atmospheric air pollution on the schoolyards. In blood smears (stained with Romanovsky-Giemsa) AR number was counted and determined their morphological types and the morphology. The modification of red blood cells was evaluated. Results. It was stated that with increase of the air pollution index the intensity of autorosette-formation (ARO) in the blood increased. AR morphotype depends on the nature of rosette cells (leukocyte), to which at least three modified autologous erythrocytes are tightly fixed. Leukocytal AutoRotate formed by neutrophils, monocytes, eosinophils, basophils, and large, medium and small platelet aggregates were distinguished. Conclusions. Contaminated atmospheric air is a risk factor for the health of children and adolescents. AR morphotype depends on the nature of the rosette cells. The frequency of the ARC in the peripheral blood grows with increasing number of modified red blood cells. Further research is needed in this area.
