umbelliferone/infarction

Laser speckle imaging of the exposed cerebral cortex allows detailed examination of the time course and topography of perfusion under different experimental conditions. Here we examine the quantitative capacity of the method and its sensitivity for the detection of peri-infarct depolarisations

The objective of this study was to determine the effect of nimodipine on infarct development and local brain pH after middle cerebral artery occlusion in the rat. Female Fischer-344 rats were subjected to permanent occlusion of the left middle cerebral artery by electrocoagulation. After 6, 12, or

Genomic screening of hybrids from stroke-prone (SHR-SP) and stroke-resistant spontaneously hypertensive rats (SHR) identified a STR1 locus on the rat chromosome 1, which correlates with the susceptibility to cerebral stroke but not with hypertension. The authors examined whether this genetic

The present study was to investigate cardioprotective effects of umbelliferone (Umb) on coronary artery ligation-induced myocardial ischemia. The model of myocardial ischemia (MI) was induced by ligatured the left anterior descending coronary artery of SD rats. ST-segment elevation, lactate

Myocardial infarction (MI) is a leading major health problem with increased morbidity and mortality worldwide. The present study investigates isoproterenol (ISO) induced MI and the beneficial role of Aegle marmelos fruit extract (AMFE) in rats. Our results indicated the significant augmentation of

Umbelliferone (UMB), a natural antioxidant belonging to coumarin derivatives, is able to cross the blood-brain barrier and protect neuronal cells from death. Here we aimed to investigate the effects of UMB in a rat model of focal cerebral ischemia induced by middle cerebral artery

OBJECTIVE In vivo panoramic imaging of reduced nicotinamide adenine dinucleotide (NADH), intracellular brain pH (pHi), and cortical blood flow was used to characterize the ischemic penumbra during focal ischemia. During global ischemia, hypoxia, and status epilepticus, the development of cortical

For the validation of volume-selective 1H and 31P NMR spectroscopy of the brain methods are required that allow high resolution quantitative mapping of tissue pH and metabolites on intact brain slices. The following techniques are proposed for this purpose. Tissue pH is imaged on cryostat sections

The effect of focal ischemia on tissue pH was studied at various times up to 6 hours after permanent middle cerebral artery occlusion in rats. Tissue pH was imaged by using umbelliferone fluorescence and correlated with cerebral blood flow, ATP content, and recordings of the steady potential.

The purpose of this study was to test the hypothesis that the efficacy of 7-nitroindazole (7-NI), a selective neuronal nitric oxide (NO) synthase (NOS) inhibitor, is pH dependent in vivo during focal cerebral ischemia. Wistar rats underwent 2 h of focal cerebral ischemia under 1% halothane
