Title: Some aspects of basic psychopharmacology: the trace amines. Author: Boulton AA. Journal: Prog Neuropsychopharmacol Biol Psychiatry; 1982; 6(4-6):563-70. PubMed ID: 6298892. Abstract: 1. Some recent research on the behavioural effects of phenylethylamine and some recent data implicating the trace amines in schizophrenia, agoraphobia and aggression are briefly outlined. 2. Phenylethylamine produces in mice a distinctive hyperactivity syndrome consisting of two phases; it appears to act via dopamine and 5-hydroxytryptamine on different components of these stereotypies. 3. Urinary unconjugated tryptamine, and meta- and para-tyramine appear to be excreted in reduced amounts in schizophrenia and bipolar depression. 4. The blood levels of the trace acids phenylacetic and meta- and para-hydroxyphenylacetic are reduced in schizophrenia. 5. Blood levels of conjugated phenylacetic and unconjugated para-hydroxyphenylacetic acid are reduced in violent as opposed to non-violent offenders. 6. The neuromodulatory role of the trace amines and their possible involvement in components of behaviour and certain mental disorders are discussed.[Abstract] [Full Text] [Related] [New Search]
