  2. 16. Pharmacological interventions against myocardial ischemia and reperfusion injury

    Author : Lars O Karlsson; Göteborgs universitet; []
    Keywords : Myocardial reperfusion injury; opioids; cyclosporine A;

    Abstract : Background: Ischaemic heart disease is the leading cause of death in the industrialised world. Although the concept of early restoration of coronary blood-flow constitutes an important factor to reduce the injury caused by myocardial ischaemia, reperfusion in itself can aggravate the damage to myocardial tissue, a phenomenon denoted myocardial reperfusion injury.

  4. 17. Regeneration in the adult brain after focal cerebral ischemia : exploration of neurogenesis and angiogenesis

    Author : Wei Jiang; Jukka Jolkkonen; Umeå universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; neurogenesis; angiogenesis; rats; mice; gliosis; BrdU; CBF; protein synthesis; ATP; penumbra; reperfusion; VEGF; 3-D confocal; photothrombosis; MCAO; Medicine; Medicin;

    Abstract : Background: Ischemic stroke ranks as the third major cause of clinical mortality and the leading cause of handicap in adults. Each year, stroke occurs in about 30,000 Swedes. The severity of an acute ischemic stroke depends mainly on the degree and duration of local cerebral blood flow (lCBF) reduction. READ MORE

  5. 18. Cellular and molecular mechanisms of ischemic brain damage in hyperglycemic rats

    Author : Hiroyuki Uchino; Lund Wallenberg Neurocentrum; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Reperfusion injury; Mitochondria; Permeability transition; Cyclosporin A; Neurotrophins; Seizures; Brain damage; Acidosis; Hypercapnia; Ischemia; Hyperglycemia; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Abstract : The present study is centered on mechanisms of ischemic brain damage in hyperglycemic animals, and in those in which exaggerated intraischemic acidosis was induced by superimposed hypercapnia in normoglycemic animals. The initial experiments were focussed on the pathophysiology of postischemic seizures. READ MORE

  6. 19. Intestinal effects of lung recruitment maneuvers

    Author : Jonas Claesson; Ola Winsö; Stefan Lehtipalo; Conny Arnerlöv; Björn Biber; Göran Hedenstierna; Petter Aadahl; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acute lung injury; oleic acid lung injury; ischemia; reperfusion injury; swine; mechanical ventilation; lung recruitment; splanchnic circulation; laser Doppler flowmetry; tissue oxygen tension; microdialysis; lactate; glycerol; Anaesthetics and intensive care; Anestesiologi och intensivvård; lungmedicin; Lung Medicine;

    Abstract : Background and aims: Lung recruitment maneuvers (brief episodes of high airway pressure) are a modern treatment alternative to achieve open lung conditions under mechanical ventilation of patients with acute lung injury. It is well known that positive pressure ventilation with high airway pressures cause negative circulatory effects, and that the effects on regional vascular beds can be even more pronounced than the systemic effects.

  7. 20. Acute skeletal muscle ischemia and reperfusion in the rat : The role of leukocytes and the effect of hyperbaric oxygen on microcirculation and metabolism during reperfusion

    Author : Allan Sirsjö; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Much experimental work in recent years seems to indicate that reperfusion after long periods of ischemia can damage tissue. Suggested factors of importance are accumulation of polymorphonuclear leukocytes (PMNs) and production of reactive oxygen metabolites (ROMs). READ MORE
