The Role of 5-Hydroxyindoleacetic Acid in Neuroendocrine Tumors: The Journey So Far [PDF]
International Journal of Endocrine Oncology, 2019 5-Hydroxyindole acetic acid (5-HIAA) is a surrogate marker for serotonin measurement and one of the first biochemical markers used in neuroendocrine tumors. In this review, we give a brief history of 5-HIAA and its precursor serotonin.

Neurotransmitter evaluation in the hippocampus of rats after intracerebral injection of TsTX scorpion toxin [PDF]
Journal of Venomous Animals and Toxins including Tropical Diseases, 2009 TsTX is an α-type sodium channel toxin that stimulates the discharge of neurotransmitters from neurons. In the present study we investigated which neurotransmitters are released in the hippocampus after TsTX injection and if they are responsible for

Increase of Urinary 5-Hydroxyindoleacetic Acid Excretion but Not Serum Chromogranin a Following Over-The-Counter 5-Hydroxytryptophan Intake [PDF]
Canadian Journal of Gastroenterology, 2008 BACKGROUND: 5-hydroxyindoleacetic acid (5-HIAA) excretion is commonly measured for biochemical detection of carcinoid tumours. A 77-year-old woman was referred for elevated 24 h urine 5-HIAA excretion (510 μmol/day; normal is less than 45 μmol/day) and ...

Specific Photometric Determination of 5-Hydroxyindoleacetic Acid in Urine
Clinical Chemistry, 1973 Abstract Udenfriend‘s nitrosonaphthol test for 5-hydroxyindoleacetic acid (5-HIAA) is subject to interference by urinary phenolic acids and drug metabolites. Studies in our laboratory have shown that the specificity and sensitivity of the nitrosonaphthol reaction with 5-hydroxyindoles can be greatly enhanced by the addition of 2 ...
