5-hydroxyindoleacetic acid (5-HIAA) is a metabolite of serotonin, a chemical/neurotransmitter that is needed by the nervous system, mainly the brain, and also needed by special cells in the lung and gastrointestinal tract. After the body uses serotonin, it is degraded in the liver and is ...
5-Hydroxyindoleacetic acidDetoxicationLevels of 5-hydroxyindoleacetic acid, 5-HIAA, the main serotoninergic metabolite in the central nervous system, were investigated in the cerebrospinal fluid, CSF, of male alcoholics and healthy controls. During intoxication, 5-HIAA correlated positively to blood ...

(1) The concentration of 5-hydroxyindoleacetic acid (5-HIAA) in the cerebrospinal fluid (CSF) (refs. 4 and 5) and the urinary concentrations of 5-HT (ref. 6) and 5-HIAA (refs. 7 and 8) are unusually low. (2) The transformation of 5-hydroxytryptophan into 5-HT seems to be ...

However, the 5-HIAA levels in the light and dark phases in the striatum or hippocampus did not significantly differ. The homovanillic acid (HVA) level was significantly higher in the dark phase than in the light phase in the mPFC and striatum. These findings indicate that the extracellular 5...

We examined the influence of adrenalectomy (ADX), and chronic corticosterone (CORT) replacement, on serotonin (5-HT) and 5-hydroxyindolacetic acid (5-HIAA) levels in discrete hypothalamic areas of the rat brain. A significant decrease in 5-HT (25%) and 5-HIAA (28%) content was observed...
