The effects of alpha-sialylcholesterol (alpha-SC), a synthetic ganglioside analogue, on synaptic neurotransmission were studied using in vivo microdialysis technique. Application of alpha-SC through a microdialysis probe enhanced high potassium-evoke

Changes of extracellular glucose and lactate in hippocampus for freely moving rats during the operant conditioned reflex were examined simultaneously. Samples of the dialysate were assayed for both glucose and lactate using in vivo microdialysis and

A method based on pre-capillary derivatization with luminol (3-aminophthalhydrazide) for carbohydrate analysis using capillary electrophoresis with on-line chemiluminescence (CL) detection was developed. The derivatives of seven monosaccharides were

A novel method had been developed to prepare ADS packings. Different alkyl-chains were bound onto Develosil60-5μ silica (particle size dp = 5 μm, s = 400–450m2/g) with γ-glycidoxypropy-ltrimethoxysilane as coupling agent and hydrophilic diol pha

An approach that exploits the surface of a solid adsorbent is proposed for precolumn FMOC derivatization of amino acids and peptides. Amino acids (Ser, Glu, GABA, Val, Phe, Lys) and two neuropeptides (substance P and Leuenkephalin) were adsorbed on a

O(2) concentration ([O(2)]) in air equilibrated solutions at room temperature is three fold higher than that in brain extracellular fluid (ECF), and CO(2) concentration ([CO(2)]) is 100 times lower. Using microdialysis the ECF is routinely dialyzed a

Due to complex influence, such as utilization and permeability of arterial vessels to oxygen, there is a considerable difference of oxygen tension between extracellular fluid and perfusate usually used in microdialysis (30–60 Torr versus 145 Torr).
