title: Changes in the serotonin and 5-hydroxyindoleacetic acid contents in rat brain after ethanol and disulfiram treatments.
abstract: Disulfiram (700 mg/kg, p.o.) significantly increased the brain levels of serotonin (5-HT) and 5-hydroxyindoleacetic acid (5-HIAA) in rats. Ethanol (1 g/kg and 2 x 1.5 g/kg, i.p.) did not affect the 5-HT level, but at the higher dose it significantly increased the 5-HIAA level. When disulfiram was given in combination with ethanol, the brain level of 5-HT was significantly higher and, conversely, the 5-HIAA level was significantly lower, as compared to the results with disulfiram alone. These results suggest that the biogenic aldehyde derived from 5-HT may influence 5-HT metabolism and the elimination of 5-HIAA from the brain.
