title: [Serotonin content in different sections of the brain, liver, intestines and blood of rats predisposed and not predisposed to alcohol consumption].
abstract: Experiments were made with white random-bred rats (males) exposed to ethanol. The content of serotonin measured by spectrofluorometry was higher in the hypothalamus, brain stem and intestine, and was lower in the thalamus, striatum liver and blood in the animals predisposed to voluntary alcohol consumption and with lateral position duration 62 +/- 18 min as compared with the animals not predisposed to alcohol consumption and with lateral position duration 196 +/- 23 min, the dose of ethanol being 4.5 g/kg i. p. Thirty minutes after ethanol administration in a dose of 2.5 g/kg i. p. to the alcohol-predisposed rats there was a lowering of the serotonin content in the hypothalamus and an increase in the thalamus, brain stem, liver and blood. Meanwhile in the rats not predisposed to alcohol consumption, the serotonin content rose in the hypothalamus, brain stem, liver, intestine and blood and fell in the thalamus and striatum. It is assumed that the serotoninergic system of the brain may play a role in the formation of "positive" or "negative" attitudes to ethanol in the population of white random-bred rats.
