This study examined the temporal profile of ischemic neuronal damage following transient bilateral forebrain ischemia in the rat model of four-vessel occlusion. Wistar rats were subjected to… (More)
A new model of transient, bilateral hemispheric ischemia in the unanesthetized rat is described. During ether anesthesia the rat's vertebral arteries were electrocauterized through the alar foramina… (More)
Transient ischemia in animals produces delayed cell death in vulnerable hippocampal neurons. To see if this occurs in humans, we reexamined brain slides from all patients with anoxic-ischemic… (More)
We examined the relationships between intracellular pH (pHi) and interstitial pH (pHe) in a rat model of focal ischemia. Interstitial pH was measured with pH-sensitive microelectrodes, and the… (More)
Lactic acidosis has been proposed to be one factor promoting cell death following cerebral ischemia. We have previously demonstrated that cultured neurons and glial are killed by relatively brief (10… (More)
This article describes a 3-year experience with focal neocortical ischemia in three rat strains. Multiple groups of adult Wistar (n = 50), Fisher 344 (n = 31), and spontaneously hypertensive (n = 72)… (More)
Severe, transient global ischemia of the brain induces delayed damage to specific neuronal populations. Sustained Ca2+ influx through glutamate receptor channels is thought to play a critical role in… (More)
The respective influences of ischemic neuronal damage and infarction on the development of abnormal blood-brain barrier (BBB) permeability and cerebral edema were evaluated in a rat model of… (More)
Animal experiments employing controlled degrees of cerebral ischemia have demonstrated that elevated blood-brain glucose concentrations greatly enhance the extent and degree of subsequent brain… (More)
