TRYPTOPHAN AND 5‐HYDROXYINDOLEACETIC ACID IN HUMAN CEREBROSPINAL FLUID
Journal of Neurochemistry, 1974who found significantly less tryptophan in the lumbar CSF of depressed patients compared to a control series. They then suggested that the ,lowered tryptophan level in CSF might indicate a lowered brain tryptophan concentration in mental depression. Thus, it is possible that the levels of tryptophan in the CSF indicate the rate of turnover of brain SHT,

Estimation of human blood plasma 5‐hydroxyindoleacetic acid and homovanillic acid
Biomedical Chromatography, 1990AbstractA method for simultaneous quantification of plasma homovanillic acid and 5‐hydroxyindoleacetic acid has been developed, permitting more efficient neurochemical examinations of these often interrelated biogenic amine systems. Zinc sulphate and sodium hydroxide solutions were used for precipitating the protein in plasma prior to injection on the ...

The Excretion of 5-Hydroxyindoleacetic Acid in Mental Patients
1965Publisher Summary This chapter discusses the effect of reserpine on the urinary excretion of 5-hydroxyindoleacetic acid (HIAA) in mental patients. The patients used in this study were carefully selected for long-term studies on aging and mental disease and were available for short-term experiments.

LUMBAR CSF 5- HYDROXYINDOLEACETIC ACID AND HOMOVANILLIC ACID IN AFFECTIVE SYNDROMES
The Journal of Nervous and Mental Disease, 1974Lumbar cercbrospinal fluid (CSF) 5-hydroxyindoleacetic acid (5-HIAA) and homovanillic acid (HVA) have been measured following probenccid administration in psychiatric patients. Values obtained probably reflect composite rates of formation of these acid monoamine metabolites at various sites within ...

False-Positive Tests for Urinary 5-Hydroxyindoleacetic Acid
JAMA, 1970A metabolic by-product of glyceryl guaiacolate, a widely used expectorant, causes a false-positive increase in urinary 5-hydroxyindoleacetic acid (5-HIAA) in laboratory tests. This interference may result in confusion during evaluation of patients for the carcinoid syndrome.
