OBJECTIVE
Dopamine is often used in the treatment of traumatic brain injury to maintain cerebral perfusion pressure. However, it remains unclear whether dopamine contributes to secondary brain injury caused by vasoconstriction and resulting diminished cerebral perfusion. The present study

Cerebral blood flow (CBF) and extent of irreversible tissue damage as well as the time course of extracellular concentration of amino acids, substrates of energy metabolism, and purine metabolites, intracranial pressure and tissue oxygen tension were assessed in 34 patients with large strokes

Lung injury was induced in young rats by a continuous infusion of hypoxanthine intravenously and breathing 100% oxygen for 48 h (group 1). Control animals were rats infused glucose and breathing 100% oxygen (group 2), rats infused hypoxanthine in room air (group 3), and untreated rats (group 4). In

We investigated in vitro whether endothelial cell edema is induced by cellular hypoxia or oxygen radical formation. Measurements of relative cell volume (RCV) were made using microweight analysis, liquid scintillation spectrometry and analysis of cellular protein content. To validate this method of

OBJECTIVE
The pathogenesis of cerebral edema in acute liver failure is suggested, in in vitro and animal studies, to involve a compromised oxidative metabolism with a decrease in cerebral ATP levels and an increase in purine concentrations. In this study we hypothesize that the cerebral

OBJECTIVE
Disturbance of calcium homeostasis contributes to evolving tissue damage and energetic impairment following traumatic brain injury (TBI). Calcium-mediated activation of calcineurin results in production of tissue-damaging nitric oxide and free oxygen radicals. Inhibition of calcineurin

We studied the cerebral effects of oxygen-derived free radicals generated from the xanthine oxidase/hypoxanthine/ADP-Fe3+ system. Xanthine oxidase/hypoxanthine/ADP-Fe3+ solution (0.1 ml) was infused into caudate putamen, and brain was frozen rapidly in situ. Brain water and sodium content increased

OBJECTIVE
Our purpose was to study the effect of fetal asphyxia on the release of hypoxanthine and xanthine in cerebrospinal fluid and on brain histologic characteristics.
METHODS
In seven fetal lambs (3 to 5 days after surgery, gestational age 124.3 +/- 2.6 days) asphyxia was induced by restriction

After 1 hour of arterial or venous occlusion, the circulatory and metabolic events in island skin flaps of the pig were studied. Both occlusion types showed significant but transient increases in glucose uptake and a parallel release of lactate, hypoxanthine, and potassium. Oxygen uptake and

Adenosine is a possible mediator of myocardial and skeletal muscle blood flow regulation. Whether adenosine plays a similar role in modulating the pulmonary pressor response to acute alveolar hypoxia is not known. Adenosine levels (nmol/g tissue) in lung in six dogs ventilated with 95% N2, and 5%

Toxic oxygen metabolites (TOM) have been suggested to be mediators of permeability edema associated with the adult respiratory distress syndrome (ARDS). Because corticosteroids have possible beneficial effects in ARDS, we have examined the effect of methylprednisolone (MP) on TOM-induced lung edema

Identification of new therapeutic agents aimed at attenuating posttraumatic brain edema formation remains an unresolved challenge. Among others, activation of bradykinin B2 receptors is known to mediate the formation of brain edema. The purpose of this study was to investigate the

We studied the effects of oxygen-derived free radicals on the ultrastructure of brain cortical slices and the release of fatty acids from phospholipids of crude synaptosomes. Xanthine oxidase, hypoxanthine, and ADP-Fe3+, a free-radical-generating system, caused swelling of cellular processes and
