title: [Effect of ethanol on the concentration of serotonin in the brain of the rat and the excretion of 5-hydroxyindoleacetic acid].
abstract: It is found that serotonin content in the brain areas and heart of rats with low alcohol motivation decreases after 5 months of chronic consumption of 48% ethanol solution in a dose of 4 g/kg; in animals with high alcohol motivation serotonin content decreases only in the hypothalamus. Under chronic alcoholization for 1 and 12 months no considerable changes were found in serotonin level of the studied tissues. 60 min after intraperitoneal administration of 20% ethanol solution in a dose of 3 g/kg in intact animals there occurs an increase of serotonin content in the brain hemispheres and heart and its decrease in the hypothalamus; in rat with low alcohol motivation after taking ethanol for 5 months this administration evokes a decrease of serotonin content in the hypothalamus and truncus cerebri; in rats with high alcohol motivation--its decrease in the hypothalamus. Excretion of 5-oxyindoleacetic acid with urine decreases 10 months after alcohol intoxication. When rats were not given ethanol after its chronic taking for 3 months serotonin oxidation was intensified for the first day, which was not observed after 7-month alcoholization of animals.
