Modeling and Simulation of Microdialysis in the Deep - DiVA

Yang Hu - Uppsala University, Sweden

It is especially suitable for studies in transgenic mice. The construction and geometry of the CMA 7 6 kDa Microdialysis Probe tip is exactly the same as in the CMA 11. Cerebral microdialysis is proving its worth as a clinical monitoring technique for severe brain injury, in which fundamental molecules, such as glucose, lactate and pyruvate, are measured at the bedside [74, 75], and is increasing its applicability to the study of drugs in the human brain as exemplified in the present review.

CMA 7 PROBES FOR LARGE MOLECULES! The CMA 7 Microdialysis Probe is ideal for use in small areas of the brain or spinal cord of small animals. It is especially suitable for studies in transgenic mice. The construction and geometry of the CMA 7 6 kDa Microdialysis Probe … Cerebral microdialysis involves placement of a small catheter with a semipermeable membrane in the parenchyma of the brain, so that a dialysate fluid can be instilled into the catheter, allowed to equilibrate and withdrawn for analysis (Figure 20-1). 2013-03-07 and rat brain endothelial cell (RBEC) monolayers, QND also outperformed digoxin.11 In vivo microdialysis is a gold-standard technique for determination of unbound, pharmacologically active drug levels in the target tissue.

Microdialysis is a sampling method that is used to determine the extracellular concentration of neurotransmitters in the brain. The method can be applied to conscious and unrestrained animals and is very suitable for the study of the chemistry of endogenous behaviour. microdialysis (Cm,brain) were compared to the unbound drug concen-trations (Cu,brain) measured by employing unbound fraction in diluted brain homogenates.More than 2-fold differencesbetween the Cm,brain and Cu,brain were observed in five of the nine test compounds (56%). The objective of our study is to determine whether the free drug Prostacyclin Treatment in Severe Traumatic Brain Injury: A Microdialysis and Outcome Study Magnus Olivecrona,1 Marie Rodling-Wahlstro¨m,2 Silvana Naredi,2 and Lars-Owe D.

Persistent metabolic crisis as measured by elevated cerebral

1989;52(6):1741-1750.

When employed in brain research, microdialysis is commonly used to measure neurotransmitters (e.g. dopamine, serotonin, norepinephrine, acetylcholine, glutamate, GABA) and their metabolites, as well as small neuromodulators (e.g.
