RESEARCH OBJECTIVES
The Study of Morphofunctional Properties of Blood Cells and Intensity of Erythropoiesis in
Humans Subjected to Spaceflight Factors (Gematologiya/ Gematologiya Perfection) obtains new
data on the effect of spaceflight factors on the human blood system in order to expand its
diagnostic and predictive capabilities and uncover the mechanisms of shifts in hematological
indicators.
EARTH BENEFITS
Although the Gematologiya
facilitates the development of space
medicine, it is conceivable that
results can help reveal the
mechanisms of shifts in
hematological indicators for medical
conditions such as anemia and
lymphocytosis on Earth.SPACE BENEFITS
The data obtained from the
Gematologiya experiment make
possible the solution of a number of
practical issues in the medical care
system for long-term spaceflights,
particularly medical monitoring,
training, and postflight rehabilitation
of crew members.RESULTS
Stimulation of erythropoiesis (increased erythropoietin, reduced level of iron in the blood,
removal of poor-quality and old erythrocytes) during the re-adaptation period was aimed at
supporting the optimal level of red blood cells necessary for the increased oxygen demand in
tissues subjected to terrestrial gravity and increased muscular loads. Thus, the results obtained
from the Gematologiya experiment indicated that the observed effect of spaceflight factors
corresponded with the expected effect. The assumption that the cause of space anemia has
