title: [Hematological parameters of cosmonauts during space flight].
abstract: This paper present hematological data obtained during space flights of the third and the fourth prime crew flights (EO-3 and EO-4). In the EO-3 flight, RBCs, WBCs and blood formed elements were counted by the cosmonaut-researcher. In the EO-4 flight, blood was drawn by the cosmonaut-researcher and analyzed on the ground; also, blood smears treated in the Microview unit and videotaped were used. Blood parameters in EO-3 and EO-4 crewmembers were close or equal to the normal. However there were cases with changes in bends, myelocytes, neutrophils, lymphocytes; also anisocytosis, hypochromia, target-like erythrocytes, and single acanthocytes were seen. Comparison of blood smears on unstained and stained glass slides revealed significant differences in the amount of target-like erythrocytes in the same cosmonaut at the same time (on the prestained glass slide only 4 erythrocytes and no aggregates in single fields of vision were detected while on the unstained glass slide aggregates in single fields of vision were seen). Pre- and postflight examinations of bone marrow revealed polymorphocellular marrow and mature hemopoietic cells.
