Regional 5-hydroxyindoleacetic acid production in humans

Life Sciences, 1995
Veno-arterial plasma concentration differences and regional organ plasma flows were used to quantify the relative amounts of 5-hydroxyindoleacetic acid (5-HIAA) contributed by various sites into the peripheral circulation. Positive venoarterial concentration gradients were found in the hepatosplanchnic, forearm, cardiac and jugular vessels in the ...

Origin of 5-Hydroxyindoleacetic Acid in the Spinal Fluid

Science, 1971
5-Hydroxyindoleacetic acid applied intracisternally in cats does not appear in spinal fluid. Changes of 5-hydroxyindoleacetic acid concentration in the spinal cord are clearly reflected in the perfusate of the spinal subarachnoid space. Thus, 5-hydroxyindoleacetic acid in the spinal fluid originates from the spinal cord and reflects metabolic changes ...

Colorimetric and Spectrophotometric Titration of 5-Hydroxyindoleacetic Acid

Experientia, 1955
Vengono descritti due metodi, colorimetrico l'uno e spettrofotometrico l'altro, atti alla titolazione quantitativa dell'acido 5-idrossiindolilacetico in soluzioni pure o in eluati, da cromatogrammi su carta, di macchie costituite da acido 5-idrossiindolilacetico.

Excretion of 5-hydroxyindoleacetic Acid in Patients Irradiated Therapeutically

International Journal of Radiation Biology and Related Studies in Physics, Chemistry and Medicine, 1973
SummaryThe 24-hour urinary excretion of 5-hydroxyindoleacetic acid (5-HIAA) was determined in patients suffering from genital carcinoma who had been irradiated therapeutically with gamma-rays from intracavitary radium sources and/or with X-rays. Radium was applied for 46 hours, twice within two weeks.

5-Hydroxyindoleacetic Acid in the Spinal Cord and Spinal Fluid

Pharmacology, 2008
After i.v. or spinal subarachnoid application of 5-hydroxytryptamine (5-HT) in cat an increase of 5-HT, followed by augmentation of 5-hydroxyindoleacetic acid (5-HIAA), in the spinal cordis observed. Concomitantly, 5-HIAA increases in the perfusate of spinal subarachnoid space.

On the concentration of 5-hydroxyindoleacetic acid in schizophrenia: A meta-analysis

Psychiatry Research, 1996
A meta-analysis was performed on the results of a number of investigations of concentrations of the serotonin metabolite 5-hydroxyindoleacetic acid (5-HIAA) in the cerebrospinal fluid, serum, or urine of acute and chronic schizophrenic patients. Only those studies were chosen in which some degree of age and gender matching were achieved and in which ...

5‐HYDROXYINDOLEACETIC ACID IN CEREBROSPINAL FLUID OF HYDROCEPHALIC CHILDREN

Acta Paediatrica, 1969
SummaryThere was a significant increase in the level of 5‐HIAA in lumbar CSF of children with hydrocephalus compared with “non‐hydroce‐phalic” children. In “non‐hydrocephalic” children the values of 5‐HIAA were found to be highest in the newborn successively decreasing to the levels of adult persons at the age of about one year.

The Excretion of 5-Hydroxyindoleacetic Acid in Mental Patients

1965
Publisher 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.
