Regional 5-hydroxyindoleacetic acid production in humans
Life Sciences, 1995Veno-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, 19715-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 ...

5‐HYDROXYINDOLEACETIC ACID IN CEREBROSPINAL FLUID OF HYDROCEPHALIC CHILDREN
Acta Paediatrica, 1969SummaryThere 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.

Colorimetric and Spectrophotometric Titration of 5-Hydroxyindoleacetic Acid
Experientia, 1955Vengono 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.

Indomethacin therapy and the measurement of urinary 5-hydroxyindoleacetic acid
Clinica Chimica Acta, 1982Indomethacin was first introduced in 1963 for treatment of rheumatoid arthritis. About half the single oral dose is 0-demethylated and 10% is conjugated to glucuronic acid by an hepatic microsomal system, and lo-20% is excreted unchanged in the urine; a portion is N-deacylated by non-microsomal systems [I].

5-Hydroxyindoleacetic Acid in the Spinal Cord and Spinal Fluid
Pharmacology, 1971After 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.

Excretion of 5-hydroxyindoleacetic Acid in Patients Irradiated Therapeutically
International Journal of Radiation Biology and Related Studies in Physics, Chemistry and Medicine, 1973SummaryThe 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.

Methadone increases Mouse Brain 5-Hydroxyindoleacetic Acid
Nature, 1971METHADONE, a synthetic narcotic with many similarities to morphine, is currently being used extensively as a crucial part of treatment-rehabilitation programmes for heroin addiction. In the doses used for “methadone maintenance”, this compound has minor tranquillizing effects, blocks the euphoric effects of heroin, eliminates drug craving, and prevents
