[Medullary layer activity of the rat adrenals after a flight on the Kosmos-1129 biosatellite].
After a 18.5-day space flight on Cosmos-1129 rat adrenals were investigated for the concentration of catecholamines and activity of enzymes involved in their synthesis, i.e. tyrosine hydroxylase, dopamine-beta-hydroxylase, and phenyl ethanol amine-N-methyl transferase. It was found that inflight the sympatho-adreno-medullary system of rats was not exposed to a prolonged or strong stressogenic effect. Postflight the rats showed an increased reactivity to the immobilization stress.
