MK-801 protects the neonatal brain from hypoxic-ischemic damage.
Enhanced synaptic release of excitatory amino acid neurotransmitters may contribute to brain injury from hypoxia-ischemia (Meldrum, 1985; Simon et al., 1984). To examine this hypothesis in neonatal brain we tested MK-80I , a novel noncompetitive N-methyl-D-aspartate (NMDA) receptor antagonist, using an in vivo experimental model of hypoxic-ischemic forebrain injury (Johnston, 1983). To induce i...
متن کاملThe effects of MK-801 and U-83836E on post-ischemic reperfusion injury in rat brain.
Rats were subjected to incomplete cerebral ischemia induced by occlusion of common carotid arteries for 30 min, and subsequent reperfusion for 15 min. The concentrations of reduced glutathione (GSH), malondialdehyde (MDA) and superoxide dismutase (SOD) activity were determined in the dorsal hippocampus in order to evaluate their changes during ischemia and reperfusion following ischemia. The de...
متن کاملClinical physiology and mechanism of dizocilpine (MK-801)
Dizocilpine (MK-801), an extensively investigated drug possessing secondary amine and benzenoid functions, displays a wide array of biological properties, including anticonvulsant and anesthetic. There is scant discussion of biomechanism. A relevant, important finding is formation of oxidative metabolites in the hydroxylamine and phenolic categories. Analogy to cocaine metabolites suggests part...
متن کاملMK-801 prevents hypobaric-ischemic neuronal degeneration in infant rat brain.
Recent evidence implicates the endogenous excitatory amino acids, glutamate (Glu) and aspartate, in hypoxic/ischemic neuronal degeneration. In a preceding article (Ikonomidou et al., 1989) we described a new model for studying hypoxic/ischemic neuronal degeneration in the infant rat brain that entails unilateral common carotid artery ligation followed by exposure to a partial vacuum for 75 min....
متن کاملProtective effect of dizocilpine (MK-801) on TNBS-induced experimental colitis in mice
Ulcerative colitis is chronic and recurrent disease of the gastrointestinal tract with uncertain etiology and incomplete treatment options. N-methyl-d-aspartate (NMDA) receptor suppression has shown anti-inflammatory effects in vitro and in vivo. The aim of present study was to evaluate the role of dizocilpine (MK-801), a noncompetitive NMDA receptor antagonist, on TNBS (trinitrobenzene sulfoni...
