Sustained accumulation of excitatory amino acids and other neuroactive substances may contribute to the delayed progression of infarction in focal ischemia. Following occlusion of the left middle cerebral artery (MCAO), extracellular amino acid and purine catabolite concentrations as well as local
We simultaneously measured neurotransmitter amino acids by the microdialysis technique and cortical CBF by laser-Doppler flowmetry in the ischemic penumbral cortex of rats subjected to 2-h normothermic (36.5-37.5 degrees C) transient middle cerebral artery (MCA) clip-occlusion. Brains were
Amino acid transmitters and cations were assessed in the frontal cortex and hippocampus of 12 Alzheimer's disease (AD), 4 multi-infarct dementia (MID) patients, and 12 age-matched controls. In the hippocampus, but not in the frontal cortex of AD patients we observed an increase of sodium (Na) and a
OBJECTIVE
Clomethiazole is a neuroprotective drug that enhances gamma-aminobutyrate type A (GABA(A)) receptor activity. Its efficacy and safety were tested in the CLomethiazole Acute Stroke Study (CLASS). The protocol allowed a CT scan to be done after randomization but within 7 days of stroke onset
BACKGROUND
Several drugs that primarily act on gamma-aminobutyrate or muscarinic receptors have been used to treat downbeat nystagmus (DBN) syndrome despite their having only moderate success and causing several side effects that limit their effectiveness. These drugs were tested under the
Cerebral ischemia-reperfusion (I/R) injury usually contributes to mortality and disability after ischemic stroke. Ginkgolides injection (GIn), a standard preparation composed of ginkgo diterpene lactones extract, is clinically used for neuroprotective treatment on reconvalescents of cerebral
