Concentration gradients of monoamine metabolites in human cerebrospinal fluid.

Lateralized effect of cerebral infarction on spinal fluid monoamine metabolite concentrations in rats.

Using a rat model of stroke, we studied the effect of unilateral middle cerebral artery ligation on cerebrospinal fluid monoamine metabolites at different intervals over a 40-day postoperative period. Male Sprague-Dawley rats were divided into four groups: an unoperated control group (n = 9), a sham-operated group (n = 9), a right middle cerebral artery ligation group (n = 10), and a left middl...

Simultaneous determination of four monoamine metabolites and serotonin in cerebrospinal fluid by "high-performance" liquid chromatography with electrochemical detection; application for patients with Alzheimer's disease.

We describe an optimized, sensitive assay procedure for simultaneously determining 3-methoxy-4-hydroxyphenylglycol, 3,4-dihydroxyphenylacetic acid, and serotonin in human lumbar cerebrospinal fluid. The assay is based on liquid chromatography with an electrochemical detection system equipped with a newly developed, highly sensitive graphite electrode. Before assay, samples are deproteinized wit...

PS238. Altered balance between monoamine metabolites in human cerebrospinal fluid with major depressive disorder.

Cerebrospinal fluid nerve growth factor and total protein concentration in the children with meningitis

Meningitis is one of the most common infectious cerebral nervous system (CNS), defined as an inflammation of the meninges. It is clinically categorized into a chronic and acute based on the acuity of symptoms. Vomiting, bulging fontanel and fever are the main symptoms in the patients with meningitis. Bacterial meningitis is a severe, potentially life-threatening infection that is associated wit...

Monoamine related functional gene variants and relationships to monoamine metabolite concentrations in CSF of healthy volunteers

BACKGROUND Concentrations of monoamine metabolites in human cerebrospinal fluid (CSF) have been used extensively as indirect estimates of monoamine turnover in the brain. CSF monoamine metabolite concentrations are partly determined by genetic influences. METHODS We investigated possible relationships between DNA polymorphisms in the serotonin 2C receptor (HTR2C), the serotonin 3A receptor (H...
