while a wide array of pathological changes occur in cerebral arteries following subarachnoid hemorrhage (sah), the most consistent is endothelial damage. since the endothelium normally modulates reflexes that influence vascular tone, any damage to it may represent a significant contributor to cerebral vasospasm following sah. this experimental study investigates the correlation between endothel...

AIm: This study aims to apply computed tomography perfusion imaging (CTPI) technology under in vivo conditions in order to explore its reliability and accuracy in evaluating the rat acute cerebral ischemia-reperfusion model (RACIRM). mAterIAl and methOds: The thread embolism method was used in 48 rats to create the RACIRM. Rats were divided into 2 groups as ischemia group and ischemia-reperfusi...

Background: Hyperthyroidism as a risk factor for stroke is not conclusive. There are no definite data on the relationship between ischemic cerebrovascular injury and hyperthyroidism. This study was designed to define whether the outcomes of post-ischemic stroke injury are influenced by chronic hyperthyroidism. Methods: Two groups of hyperthyroid (HT) and control euthyroid rats of equal numbers ...

Introduction: Cerebral edema could be caused by mild or moderate traumatic brain injury. The primary modality for cerebral is head computed tomography (CT), however the interpretation different between radiologists which due to subjectivity. purpose of this study determine radiologist interobserver and intraobserver reliability in on CT injury Sanglah General Hospital, Denpasar, Bali.Methods: R...

The pathophysiology of multiple disease states, including sepsis,1,2 hypertension,1 atherosclerosis,3–5 and ischemiareperfusion injury,6 is characterized by loss of the endothelial barrier function leading to the accumulation of plasma-borne proteins, tissue edema, and cell death. Importantly therapeutic strategies that inhibit loss of endothelial barrier function have been associated with stra...

The incidence and severity of primary cardiac events are inversely related to the plasma concentration of high-density lipoproteins (HDLs). We investigated whether HDLs may exert a direct cardioprotection in buffer-perfused isolated rat hearts, which underwent a 20-minute low-flow ischemia followed by a 30-minute reperfusion. The administration of HDLs at physiological concentrations (0.5 and 1...

Objective(s): Paeoniflorin (PF) has anti-oxidation, anti-inflammation, anti-apoptosis, and neuroprotection pharmacological effects against ischemic injury. The aim of the present study was to investigate the neuroprotection mechanisms of PF in cerebral ischemia-reperfusion injury rats.Materials and Methods: We established an animal model of cerebral infarct by occlusion of the middle cerebral a...

Objective(s): The aim of this study was to investigate the effects of mild hypothermia on expression of NF-E2-related factor 2 (Nrf2) and heme-oxygenase-1 (HO-1) of rat cerebral cortex and hippocampus after cardiopulmonary resuscitation and further investigate the possible mechanism of action. Material and Methods:To copy an asphyxia heart arrest model, Sprague Dawley rats were randomly divided...

Objective: The present study investigated possible neuroprotective effects of ethanolic extract of Tiliacora triandra leaf against cerebral ischemic-reperfusion injury in mice. Materials and Methods: Forty male Institute of Cancer Research (ICR) mice were randomly divided into five groups: (1) Sham + 10% Tween 80, (2) bilateral common carotid artery occlu...

Lung Cell. Mol. Physiol. 278: L3–L12, 2000.—Intestinal ischemia-reperfusion commonly occurs in critically ill patients and may lead to the development of remote organ injury, frequently involving the lu...
