Extracellular amino acid changes in patients during reversible cerebral ischaemia.
This study investigated the changes in extracellular chemistry during reversible human cerebral ischaemia. Delayed analysis was performed on samples taken from a subgroup of patients during aneurysm surgery previously reported. Frozen microdialysis samples from 14 patients who had all undergone temporary clipping of the ipsilateral internal carotid artery (ICA) were analysed for another 15 amin...

Double-barrel ion-sensitive microelectrodes were used to measure activity-related changes in extracellular pH (pHe), potassium and calcium concentration ([K+]e and [Ca2+]e) in the spinal dorsal horns of frogs. Repetitive stimulation (30-100 Hz) of the dorsal root evoked transient acidification in the lower dorsal horn by 0.25 pH units, which was accompanied by an increase in [K+]e by 4-5 mmol/l...
متن کاملAntithrombotic agents in cerebral ischaemia.
The current evidence suggests that aspirin is treatment of choice when compared to anticoagulants for patients with non-cardioembolic stroke. The usefulness of combination therapy (aspirin vs. with or without warfarin) is still debated. Likewise the combination of Aspirin with clopidogrel has no added advantage (MATCH Trial). However anticoagulant therapy significantly benefits high-risk patien...
متن کاملIncreases in GABA concentrations during cerebral ischaemia: a microdialysis study of extracellular amino acids.
OBJECTIVES Increases in the extracellular concentration of the excitatory amino acids glutamate and aspartate during cerebral ischaemia in patients are well recognised. Less emphasis has been placed on the concentrations of the inhibitory amino acid neurotransmitters, notably gamma-amino-butyric acid (GABA), despite evidence from animal studies that GABA may act as a neuroprotectant in models o...
