The blood-brain barrier breaks down following cerebral ischemia, but the exact sequence of events for extravasation of serum proteins and their parenchymal distribution remain uncertain. We studied the distribution of serum albumin in the hippocampus of the gerbil brain using light and electron
Albumin, the most abundant plasma protein, is known to exhibit a neuroprotective effect in animal models of focal and global cerebral ischemia. In the present study, the expression and immunoreactivity of albumin was examined in the hippocampus following 5 min of transient cerebral ischemia in
Impairment of the blood-brain barrier (BBB) after cerebral ischemia leads to extravasation of plasma constituents into the brain parenchyma. We describe a novel method using non-invasive near-infrared fluorescence (NIRF) imaging and bovine serum albumin labeled with a NIRF dye (NIRF-BSA) to detect
Human albumin therapy is highly neuroprotective in focal cerebral ischemia. Because albumin is the main carrier of free fatty acids (FFA) in plasma, we investigated the content and composition of plasma FFA in jugular vein (JV), femoral artery (FA) and femoral vein (FV) of rats given intravenous
Treatment with human albumin administered intravenously in the immediate post-ischemic period following a 2-h period of transient focal cerebral ischemia leads to a reduction of cortical infarction in rat. Immunohistochemistry with antibodies to rat immunoglobulins (IgG), rat albumin and (exogenous)
OBJECTIVE
To determine whether there is any differential benefit of albumin administration within 2 h of onset of ischemia and in settings (severe ischemia with reperfusion in cardioembolic strokes with National Institutes of Health Stroke Scale [NIHSS] ≥15), most representative of experimental
BACKGROUND
Hemodilution has had limited success as a treatment of cerebral ischemia. When using a non-oxygen-binding fluid, the therapeutic efficacy of hemodilution-induced increases in blood flow are offset by concomitant decreases in oxygen content.
METHODS
The effect of hemodilution, with
We have shown that high-concentration albumin therapy is markedly neuroprotective in focal cerebral ischemia. The present study was conducted to ascertain the degree to which hemodynamic alterations are responsible for this therapeutic effect. Normothermic, physiologically regulated male
Recent investigations have proposed that, after temporary ischemia, pentastarch may reduce microvascular permeability and reperfusion injury. However, this hypothesis has not been tested in the brain. Accordingly, after 180 min of temporary middle cerebral artery occlusion, the effect of pentastarch
In recent experimental studies, we demonstrated a highly beneficial neuroprotective effect of moderate- to high-dose human albumin treatment of transient focal cerebral ischemia, but we did not define the effect of albumin therapy in permanent focal cerebral ischemia. In this study, anesthetized
Albumin is known to have neuroprotective effects. The protein has a long half-life circulation, and its effects can therefore persist for a long time to aid in the recovery of brain ischemia. In the present study, we investigated the neuroprotective effects of human serum albumin (HSA) on brain
We investigated the temporal profile of the extravasation of serum albumin in a reproducible gerbil model of unilateral cerebral ischemia, using immunohistochemical and dye-tracer techniques to evaluate albumin accumulation and the occurrence of active extravasation, respectively. After 30 min of
OBJECTIVE
It is well known that residual cortical cerebral blood flow plays a pivotal role in the pathophysiology of cerebral ischemia and can influence the outcome of recanalization therapy. This study examined the impact of residual cortical cerebral blood flow on the neuroprotective efficacy of
The objectives were to study plasma and erythrocyte flow in an area of acute focal cerebral ischemia and define their relationship to developing microcirculatory obstruction as determined by morphological techniques. Eighteen adult cats, anesthetized with ketamine hydrochloride, had right middle
Nitroxide free radicals are known to protect cells from oxidative damage. Diffusion-weighted and perfusion-weighted magnetic resonance imaging was used to evaluate the effects of polynitroxyl albumin (PNA) in a middle cerebral artery intraluminal suture model of transient focal cerebral ischemia in
