| Zusammenfassung |
| Researches of last two decades have shown that the cardiovascular system represents the most
probable target for influence of helio - and geomagnetic activity. Both cardiovascular system
and system of blood are connected very closely: one system cannot exist without another. For
the same reason the effects perceived by one system, are easily transferred to another.
Laboratory tests such as blood coagulation, platelet aggregation, and capillary blood velocity
(CBV) performed in Scientific Clinical Center JSC "Russian Railways in patients suffering
from coronary heart disease (CHD) revealed a high dependence with a level of geomagnetic
activity.
Results of these and other findings allow to assume that blood itself can be a sensor of
geomagnetic fields variations because erythrocytes, platelets, and leucocytes bearing electric
charge on membranes, and in a comparable magnetic field can change as own properties and
properties of blood flow. It is interesting that not only geomagnetic disturbances, but also
the periods of very quiet geomagnetic conditions affect a capillary blood velocity,
slowing down it. It was shown during long-term experiment with isolation named
“MARS-500” in spatial facility of the Institute of Biomedical Problems in Moscow
as imitation of an extended space mission to Mars. Using digital capillaroscope
“Russia”, two crewmembers - medical doctors made records of microcirculation
parameters at themselves and other four participants of “Martian” team. Capillary records
were performed before, during, and after period of isolation in medical module of
MARS-500 facility. At the period of experiment nobody of crewmembers knew about
real geomagnetic conditions. In days of active geomagnetic conditions average
CBV has registered as 389 ± 167 μm/s, that statistically significant (p |
