Altered serous levels of monoamine neurotransmitter metabolites in patients with refractory and non-refractory depression.

Neural regeneration research

Zhang G, Zhang Y, Yang J, Hu M, Zhang Y, Liang X.
PMID: 25722703
Neural Regen Res. 2012 May 15;7(14):1113-8. doi: 10.3969/j.issn.1673-5374.2012.14.011.

The study examined plasma metabolite changes of monoamine neurotransmitters in patients with treatment-resistant depression (TRD) and non-TRD before and after therapy. All 30 TRD and 30 non-TRD patients met the diagnostic criteria for a depressive episode in accordance with...

The current study presents preliminary data regarding the development and validation of a rating system designed to classify PD patients into clinical subgroups. Using portions of the Unified Parkinson's Disease Rating Scale, a ratio value was derived, yielding three...

Tryptophan depletion selectively reduces CSF 5-HT metabolites in healthy young men: results from single lumbar puncture sampling technique.

The international journal of neuropsychopharmacology

Moreno FA, McGavin C, Malan TP, Gelenberg AJ, Heninger GR, Mathé AA, Delgado PL.
PMID: 11343605
Int J Neuropsychopharmacol. 2000 Dec;3(4):277-283. doi: 10.1017/S1461145700002133.

Plasma tryptophan (Trp) depletion is a commonly used tool for determining the role of brain serotonin (5-HT) function in a variety of psychiatric disorders. This study measured the cerebrospinal fluid (CSF) monoamine metabolite response to Trp depletion and control...

Changes in plasma monoamine metabolites during acute lithium intoxication.

Human psychopharmacology

Yoshimura R, Yamada Y, Ueda N, Nakamura J.
PMID: 12404314
Hum Psychopharmacol. 2000 Jul;15(5):357-360. doi: 10.1002/1099-1077(200007)15:5<357::AID-HUP174>3.0.CO;2-K.

A case of acute lithium intoxication is presented in which plasma levels of 3-methyoxy-4-hydroxyphenylglycol (MHPG), 5-hydroxyindoleacetic acid (5-HIAA), and homovanillic acid (HVA) were longitudinally measured during the intoxication period. Plasma levels of MHPH and 5-HIAA, but not HVA were...

The neurochemical profile of long term oral administration of moclobemide.

Pakistan journal of pharmaceutical sciences

Haleem DJ, Haider S, Yasmeen A, Parveen T.
PMID: 16414805
Pak J Pharm Sci. 1998 Jan;11(1):9-14.

Moclobemide, a benzamide derivative, predominantly inhibits the A form of monoamine oxidase (MAO) and its MAO binding is reversible. Acute administration of moclobemide has been shown to induce an increase in brain levels of monoamines and a concomitant decrease...

Increased precursor availability did not increase food intake and 5-HT turnover rate in the hypothalamus of diazepam injected rats.

PMID: 16414823
Pak J Pharm Sci. 1999 Jan;12(1):21-6.

In view of a possible role of serotonin (5-hydroxytryptamine; 5- HT) in regulation of appetite and anxiety, the effects of 1, 3 and 5 mg/kg doses of diazepam on brain serotonin precursor and effects of single and repeated diazepam...

Effects of high dose propranolol treatment on dopamine and norepinephrine metabolism in regions of rat brain.

Neuroscience letters
