BACKGROUND AND PURPOSE Spreading depressions (SDs) occur in experimental focal ischemia and contribute to lesion evolution. N-Methyl-D-aspartate (NMDA) antagonists inhibit SDs and reduce infarct size. The glycine site on the NMDA receptor complex offers a therapeutic target for acute focal ischemia, potentially devoid of many side effects associated with(More)
OBJECTIVE To explore the utility of intravenous (i.v.) prourokinase treatment, we compared intra-arterial (i.a.) and i.v. delivery in a rat embolic stroke model, using diffusion (DWI) and perfusion (PI) magnetic resonance imaging to assess in vivo effects on ischemic lesion evolution and reperfusion. BACKGROUND Thrombolytic therapy with recombinant(More)
Two model-independent measures of diffusion, the apparent diffusion coefficient (ADC) and return-to-the-origin probability enhancement (R) were compared for their ability to detect tissue necrosis in RIF-1 murine tumors. Both reflect the degree of restriction experienced by the endogenous water molecules; however, the ADC is calculated from the initial(More)
Cation channels conduct calcium, sodium and potassium, cations that are likely deleterious in the evolution of focal ischemic injury. We studied the effects of a novel, broad-spectrum inhibitor of several cation channels, LOE 908 MS, on acute ischemic lesion development with diffusion-weighted magnetic resonance imaging (DWI) and on cerebral perfusion with(More)
