Tryptophan Metabolism in Affective Psychoses

British Journal of Psychiatry, 1966
Tryptophan has attracted attention during recent years for the possible role played by some of its metabolites in the aetiology and treatment of psychiatric disorders. Of these metabolites, serotonin has received special attention and considerable work has been carried out in order to elucidate its physiological and pharmacological actions.

Tryptophan metabolism in depressive illness

Psychological Medicine, 1974
SYSNOPSIS[Methylene-14C]-L-tryptophan was administered intravenously to five patients suffering from severe depression before and after clinical recovery, and to six control subjects; all subjects were tested while on a standard diet. [14C]-5-Hydroxyindoleacetic acid and [14C]-indoleacetic acid were isolated from urine during the following 48 hours and

Tryptophan metabolism in acrodermatitis enteropathica

The Journal of Pediatrics, 1973
Tryptophan-loading tests were performed on two normal subjects before and after diiodohydroxyquin treatment and on three acrodermatitis enteropathica patients being treated with diiodohydroxyquin. Patients who received a loading dose of tryptophan had higher urinary levels of kynurenine, kynurenic acid, and acetylkynurenine in comparison with normal ...

Tryptophan metabolism in experimental porphyria

Biochemical Pharmacology, 1967
Abstract Although there seems to be no qualitative difference in the excretion of certain urinary metabolites of l -tryptophan between normal and porphyric rats, quantitative determination showed that there is a decrease in the level of excretion of l -kynurenine and 3-OH-kynurenine.

Tryptophan metabolism in liver disease

Clinica Chimica Acta, 1971
Abstract Plasma levels of tryptophan were observed in the fasting state and after oral administration of l -tryptophan in normal subjects and in patients with chronic liver disease. Mean plasma tryptophan levels in patients with liver cirrhosis slightly but not significantly increased, while in patients with hepatic encephalopathy or coma they ...

The Control of Tryptophan Metabolism

1975
This volume as a whole describes enzyme induction mechanisms and the influences of enzyme induction upon metabolism and its control. The present chapter deals with various ways in which the metabolism of a single amino acid tryptophan is controlled. While processes influencing this include induction, the de novo synthesis of enzymes which metabolize ...
