    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cerebral oxygen delivery.; cerebral blood flow; hypervolaemic haemodilution; isovolaemic haemodilution; transcranial cerebral oximetry; transcranial Doppler ultrasound; delayed ischaemic deficit; Aneurysmal subarachnoid haemorrhage; cerebral arterial vasospasm; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : This thesis deals with cerebral arterial vasospasm and ischaemia, a serious complication after aneurysmal subarachnoid haemorrhage. Firstly is the noninvasive transcranial Doppler ultrasound and transcranial cerebral oximetry techniques evaluated in detecting cerebral arterial vasospasm in clinical practice. LÄS MER

  3. 2. Subarachnoid Hemorrhage in the Elderly

    Författare :Mats Ryttlefors; Per Enblad; Kristina Cesarini; David Mendelow; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; subarachnoid hemorrhage; intracranial aneurysm; elderly; outcome; endovascular coiling; neurosurgical clipping; secondary insult; cerebral vasospasm; Neurosurgery; Neurokirurgi;

    Sammanfattning : Subarachnoid hemorrhage (SAH) is a disease with high risk of mortality and morbidity. Elderly patients have an even higher risk of poor outcome. The incidence of SAH increases with age and the elderly constitute a substantial and increasing proportion of the population. Thus, the management of elderly SAH patients is an imminent clinical challenge. LÄS MER

  4. 3. MAPK and pro-inflammatory mediators in the walls of brain blood vessels following cerebral ischemia

    Författare :Aida Maddahi; Lund Medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mitogen activated protein kinase; iNOS; Matrix metalloproteinases; IL-1ß; IL-6; TNF-α; Inflammation; Subarachnoid hemorrhage; Middle cerebral artery occlusion;

    Sammanfattning : INTRODUCTION Stroke is a serious neurological disease which may lead to death and severe disability [1, 2]. There are two major types of stroke: ischemic and hemorrhagic stroke. LÄS MER

  5. 4. On receptor changes in cerebral arteries after subarachnoid haemorrhage

    Författare :Jacob Hansen-Schwartz; Lund Medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacognosy; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi; Pharmacological sciences; subarachnoid haemorrhage; reverse transcriptase polymerase chain reaction; in vitro pharmacology; organ culture; Endothelin receptors; 5-HT receptors;

    Sammanfattning : Overall the aim has been to characterise the in vitro upregulation of the 5-hydroxytryptamine 1B/1D (5-HT(1B/1D)) and endothelin (ET) receptors in the cerebral circulation as well as demonstrating phenotypic changes in a pathophysiological model mimicking subarachnoid haemorrhage. The first part describes receptor upregulation using organ culture of whole vessel segments from both rat and man. LÄS MER

  7. 5. Calcium calmodulin-dependent protein kinase signal transduction in cerebral arteries

    Författare :Roya Waldsee; Lund Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CAMK; Ednothelin receptors; Calcium; gene regulation;

    Sammanfattning : Cerebral arteries participate actively in the response that follows an episode of cerebral ischemia in man and rat. It has been shown that the vascular endothelin receptor expression is increased in stroke and organ culture. LÄS MER
