[Content of biogenic amines in brain under artificial and natural cooling of animals].
The catecholamines and serotonin contents in different brain areas were studies in rats under hypothermia of 30 degrees and 20-19 degrees C and in Citellus pigmaeus Pallas on the 7th, 15th and 30th day after hibernation. The artificial and natural drop in the body temperature is shown to increase the catecholamines and serotonin contents in cerebral hemispheres, cerebellum, thalamus, hypothalamus and medulla oblongata. A long artificial cooling is accompanied by a decrease in the value of the catecholamines/serotonin ratio in the brain due to an increase in the serotonin content and a long hibernation by redistribution of the content both of catecholamines and serotonin without changing their ratio.
