BACKGROUND AND PURPOSE We sought (1) to identify early metabolic markers for the development of (ir)reversible neurological deficits and cerebral infarction in subarachnoid hemorrhage (SAH) patients by using the microdialysis technique and (2) to evaluate the influence of intracerebral hemorrhage (ICH) on microdialysis parameters. METHODS We performed a prospective study of 44 SAH patients wi...

Delays between soil sampling and processing for analysis are common in both research agronomy, but the effects of storage conditions on measurements plant-available nitrogen (N) rarely considered. With increasing recognition organic N pools soils, such as amino acids peptides, it is necessary to determine how sample handling impacts outcomes quantification. In this study, we used situ microdial...

introduction: pain as a complex process in central nervous system (cns) has been studied by many researchers. pain is controlled by several cns pathways, one of the most important of which, is the descending noradrenergic system. this system begins from locus coeruleus (lc) nucleus in pons and ends in the spinal cord. in this research, the effect of pain induced by formalin was studied. methods...

in the present study, the effect of steroidal anti-inflammatory drug betamethasone (0.12, 0.24 mg/kg, i.p. acutely) on striatal glutamate level in parkinsonian rats was studied using the microdialysis technique. our results showed significant differences (p<0.05) in the level of striatal glutamate between treated and non-treated damaged rats.

objective(s):the relationship between tramadol, as an antinociceptive drug, and locus coeruleus (lc), the main noradrenergic nucleus of the brain that affects regulation and modulation of pain through descending noradrenergic pathways was investigated. materials and methods: male sprague-dawley rats were divided into four groups of 10 rats. the rats were fixed in stereotaxic instrument and then...

BACKGROUND Intravenous and subcutaneous microdialysis was performed to compare the free concentrations and pharmacokinetics of L-3, 4-dihyroxyphenylalanine (L-dopa) in blood and tissue in healthy subjects and in patients with Parkinson disease. METHODS Nine healthy volunteers and 10 patients with Parkinson disease, stage 1. 5-2 according to the Hoehn-Yahr rating scale, took part of the study....

Microdialysis has been used for 25 years to study brain function in vivo. Recently, it has been developed for investigations on peripheral tissues. A microdialysis catheter is an artificial blood vessel system which can be placed in the extracellular space of various tissues such as adipose tissue and skeletal muscle in order to examine these tissues in situ. Molecules are collected from the ti...

Cerebral microdialysis is a well-established laboratory tool that is increasingly used as a bedside monitor to provide on-line analysis of brain tissue biochemistry during neurointensive care. This review describes the principles of cerebral microdialysis and the rationale for its use in the clinical setting, including discussion of the most commonly used microdialysis biomarkers of acute brain...
