The aim of the current study was to develop and validate a new microdialysis coupled LC-MS/MS system with improved accuracy, precision, simplicit … microdialysis has further revealed that L-DOPA-stimulated dopamine release is widespread and related to the serotonergic innervation. The present Review emphasizes the functional impact of extrastriatal release of dopamine induced by L-DOPA in both the therapeutic and side effects of L-DOPA. Microdialysis was used to detect variations in extracellular DA, dihydroxyphenylacetic acid (DOPAC) and homovanillic acid (HVA) in the NAC of freely moving rats during acute and chronic morphine treatme … This study shows the effect of opiate withdrawal on dopamine (DA) in the nucleus accumbens (NAC). Quantitative microdialysis of dopamine in the striatum: effect of circadian variation.

The concentrations of dopamine and its glucuronide in the microdialysates collected from the striatum of rat brains were approximately equal (2 nM). Dopamine sulfate was not detected in the microdialysates (limit of detection 0.8 nM).

Two quantitative microdialysis methods were used to determine the concentration of extracellular dopamine in the anterior striatum of the rat. The microdialysis probe recoveries for dopamine, serotonin, methamphetamine, amphetamine, 4-hydroxymethamphetamine and 4-hydroxyamphetamine were tested in vitro. The microdialysis probes attached to the two-flow microdialysis system were incubated in well-stirred Ringer's solution bath containing 10 or 100 ng/mL of the six compounds at 37 °C. Dopamine is a catecholamine neurotransmitter that degrades rapidly in aqueous solutions; hence, its analysis following brain microdialysis is challenging.

Discussion 6. Conclusion Acknowledgments References Appendix A Appendix B Section IV The Application of Microdialysis in the Basic Neurosciences Chapter 10 A Microdialysis and Automated On-Line Analysis Approach to Study Central Cholinergic Transmission in Vivo 1 We used voltammetry to measure electrically evoked dopamine release next to microdialysis probes during the retrodialysis of dexamethasone or XJB-5-131. After the in vivo measurements, the brain tissue containing the microdialysis probe tracks was examined by fluorescence microscopy using markers for ischemia, neuronal nuclei, macrophages, and dopamine axons and terminals.
