Microdialysis Probes Probes used today are generally i-shaped, so-called cannula style, as in Fig. 2. Linear probes are used, e.g., in dermal microdialysis. Loop probes are also available but less common. The latter can be used in larger animals and can have longer membranes.

Microdialysis samples from the interstitial space which is a defined, anatomical compartment there is no net loss of body fluid the sample is “purified” and no enzymatic degradation takes place because proteins do not pass through the probe membrane into DTIC ADA561711: In Vivo Microdialysis and Electroencephalographic Activity in Freely Moving Guinea Pigs Exposed to Organophosphorus Nerve Agents Sarin and … Microdialysis Buttons The Dialysis Buttons are injected molded polystyrene. The button has a chamber which varies from 5 to 350 microliters depending upon which size button one chooses to use.

Abstract: Microdialysis has been used extensively in animal studies for decades and in human pharmacokinetic studies for about 10 years.

Microdialysis is a minimally invasive sampling technique that is used to continuous monitor free, unbound analyte concentrations in the extracellular fluid of virtually any tissue. Analytes may include endogenous molecules (e.g. neurotransmitter, hormones, glucose, etc.) to assess their biochemical functions in the body, or exogenous compounds (e.g. pharmaceuticals) to determine their Thus this technique can be used to continually measure the substance of interest in the extracellular liquid and to simultaneously deliver drugs and/or other substances to the tissue. In our murine airway preparation, a small-diameter microdialysis probe (240-μm outside diameter × 2-mm length) is positioned on the surface of the nasal cavity and the ionic composition of the dialysate is microdialysis measurements in the liver parenchyma were compared with measurements on the liver surface in association with induced liver ischemia.

Microdialysis is increasingly being used to monitor cerebral metabolism clinically in patients with traumatic brain injury, 31 and techniques have been adapted to measure drug concentrations of putative neuroactive drugs in individuals requiring neurosurgery. 20 As more human microdialysis data are generated, intraspecies differences in drug distribution in CNS compartments as well as effects Microdialysis gives you a preview of what goes on in tissues, before chemical events can be reflected as changes in systemic blood levels. The microdialysis probe is designed to mimic a blood capillary and by keeping this metaphor in mind, it is easy to conceive of the many ways you can use this technique.
