Quantitative receptor autoradiography was used to determine the distribution of excitatory amino acid binding sites in the basal ganglia of rat brain. alpha-Amino-3-hydroxy-5-methylisoxazole-4-propionic acid, N-methyl-D-aspartate, kainate, quisqualate-sensitive metabotropic and non-N-methyl-D-aspartate, non-kainate, non-quisqualate glutamate binding sites had their highest density in striatum, ...
Anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis is is most common form ofimmune-mediated encephalitis with prominent neurologic and psychiatric features at disease onset. We describe a 16 years old patient who presented with fever and status epilepticus. His MRI sequences was normal. Anti-NMDAR antibodies were detected in the CSF. MRI, CT and other studies didn,t show any tum...
Anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis is a rare condition characterized by emotional and behavioral disturbances, dyskinesias, and extrapyramidal signs. It occurs in young women of reproductive age and is classically described as a paraneoplastic phenomenon. We present a 36-year-old, HIV-positive female who was admitted to the hospital in an acute confusional state, with ...
Glutamate receptor overactivation contributes to neuron death after stroke, trauma, and epileptic seizures. Exposure of cultured rat hippocampal neurons to the selective glutamate receptor agonist N-methyl-d-aspartate (300 microm, 5 min) or to the apoptosis-inducing protein kinase inhibitor staurosporine (300 nm) induced a delayed neuron death. In both cases, neuron death was preceded by the mi...
Previous studies suggest that magnesium chloride may have discriminative stimulus effects that partially overlap with those of noncompetitive N-methyl-D-aspartate antagonists as well as certain monoamine uptake inhibitors. In our study, rats were trained to discriminate 100 mg/kg magnesium chloride from saline and its discriminative stimulus effects were characterized with respect to N-methyl-D...
BACKGROUND AND PURPOSE Despite side effects including N-methyl-d-aspartate-mediated neurotoxicity, recombinant tissue-type plasminogen activator (rtPA) remains the only approved acute treatment for ischemic stroke. Memantine, used for treatment of Alzheimer disease, is an antagonist for N-methyl-d-aspartate receptors. We investigated whether memantine could be used as a neuroprotective adjunct ...
