[Absorption and release of biogenic amines by the lung during the restorative period after hypovolemic hypotension].
The processes of serotonin and histamine absorption and release by the lungs were studied in dogs during 1 to 3.5 hour hypovolemic hypotension and during 24 hours after blood retains fusion. Absorption of biogenic amines by the lungs tended to increase in all the animals under hypovolemic hypotension. In the group of non-survivors the serotonin absorption by the lungs in the post-terminal period remained increased, while in the group of survivors it came down to normal soon, though the histamine release was increased. The above processes were aggravated in the group of animals whose lungs were affected by oleic acid. It resulted in the absorption of histamine instead of its release. The intensified absorption of biogenic amines by the lungs was accompanied by a quick fall in cardiac output, by the increase in resistance of systemic and pulmonary circulation.
