[Changes in neutral peptide hydrolase levels in the blood and catecholamine levels in the tissues during adaptation to high altitude hypoxia].

Activity of neutral peptide-hydrolases in blood plasma and content of catecholamines in the tissues of rats under conditions of their stay in mountains at different height have been studied in dynamics. Unidirectional phase changes in activity of proteolytic enzymes of blood plasma and content of catecholamines in adrenal glands are revealed. A conclusion is made on participation of neutral blood peptide-hydrolases in organism adapted to Alpine hypoxia. Relations between neutral blood peptide-hydrolases and catecholamines in the organism and possibility of their direct mutual effect are under discussion.
