Das
interstitielle Organ im schwerelosen Zustand - ein
klinisch-physiologisches Modell?
(The interstitial organ in
microgravity: a model for clinical physiology?)

We performed an experiment within the
1991 Austromir mission, 3 months preflight, on the 6th inflight
and 4th postflight days, respectively. Primary goal was to
measure changes in venous blood and plasma sound velocity (BSV,
PSV) with lower body suction (LBNP).
Contrasting earth-based findings, there
was no increase in BSV nor PSV with LBNP inflight. Postflight,
the elevation in both values was greater than expected. Taken
together with LBNP data from the German 1992 Mir cosmonaut, we
propose the hypothesis that the dynamics of tissue fluid exchange
is profoundly influenced by m-g adaptation. A further goal of the
experiment was to determine volume- and stress-sensitive
hormones.
The results need validation by
additional flight data and might be considered as an important
contribution to our understanding of the normal functioning and
pathophysiology of the interstitial organ.
