homovanillic acid and Coma

homovanillic acid has been researched along with Coma in 8 studies

Homovanillic Acid: A 3-O-methyl ETHER of (3,4-dihydroxyphenyl)acetic acid.
homovanillate : A hydroxy monocarboxylic acid anion which is obtained by deprotonation of the carboxy group of homovanillic acid.
homovanillic acid : A monocarboxylic acid that is the 3-O-methyl ether of (3,4-dihydroxyphenyl)acetic acid. It is a catecholamine metabolite.

Coma: A profound state of unconsciousness associated with depressed cerebral activity from which the individual cannot be aroused. Coma generally occurs when there is dysfunction or injury involving both cerebral hemispheres or the brain stem RETICULAR FORMATION.

ExcerptRelevanceReference
"Of five comatose patients, two had cerebrovascular lesions and three had sustained head injury, and, in four of the five, the values of either one or both of HVA and 5-HIAA were low, but in the fifth case the 5-HIAA value was high."5.26Homovanillic acid and 5-hydroxyindoleacetic acid in the ventricular CSF of comatose patients with obstructive hydrocephalus. ( Inagawa, T; Ishikawa, S; Uozumi, T, 1980)
"The main metabolites of noradrenaline, serotonin, and dopamine, methoxyhydroxyphenylglycol (MHPG), 5-hydroxyindole-acetic acid (5HIAA), and homovanillic acid (HVA), respectively, were assessed in CSF samples of patients in coma after severe head injury, the first days after the accident and again after an improvement (13 patients) or deterioration (7 patients) in their clinical state, evaluated by the score on the Glasgow Coma Scale."3.69CSF neurotransmitter metabolites in comatose head injury patients during changes in their clinical state. ( Christopoulos, M; Kotsou, A; Markianos, M; Seretis, A, 1996)
"The main metabolites of the neurotransmitters noradrenaline, dopamine, and serotonin, methoxy-hydroxyphenylglycol (MHPG), homovanillic acid (HVA), and 5-hydroxyindoleacetic acid (5HIAA) respectively, were estimated by HPLC with electrochemical detection in CSF samples from 24 patients in coma after head injury, 1 to 12 (mean 3."3.68CSF neurotransmitter metabolites and short-term outcome of patients in coma after head injury. ( Baltas, I; Kotsou, S; Markianos, M; Sacharogiannis, H; Seretis, A, 1992)
"The concentrations of homovanillic acid (HVA), 3-methoxy, 4-hydroxyphenylglycol (MHPG), and 5-hydroxyindolylacetic acid (5-HIAA) were measured in samples of ventricular cerebrospinal fluid (CSF) taken from 15 patients who were comatose as a result of an acute head injury, a tumour, or a cerebrovascular accident."3.66Amine metabolites in ventricular cerebrospinal fluid in coma. ( Tsementzis, SA; Wilson, H; Yates, CM, 1979)
"Of five comatose patients, two had cerebrovascular lesions and three had sustained head injury, and, in four of the five, the values of either one or both of HVA and 5-HIAA were low, but in the fifth case the 5-HIAA value was high."1.26Homovanillic acid and 5-hydroxyindoleacetic acid in the ventricular CSF of comatose patients with obstructive hydrocephalus.
