    Sammanfattning : Giant cell arteritis (GCA) is a chronic inflammatory disorder of medium-size and large arteries which affects people aged 50 years or older with a female preponderance. The two different expressions of GCA are temporal arteritis (TA) and polymyalgia rheumatica (PMR). LÄS MER

  3. 3. Experimental Stroke and Neurotrophins: Regulation, function and gene transfer of neurotrophins in rat and mouse models of focal cerebral ischemia

    Detta är en avhandling från Restorative Neurology, Wallenberg Neuroscience Center, University Hospital, 221 84 Lund, Sweden

    Författare :Gunnar Andsberg; Lund University.; Lunds universitet.; [2001]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsychology; Neurology; animal behaviour; striatum; stereology; immunohistochemistry; focal cerebral ischemia; nerve growth factors; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : Stroke caused by focal cerebral ischemia is a major cause of death and neurological disability in humans. The forebrain region most commonly affected by ischemic incidents is that supplied by the middle cerebral artery. LÄS MER

  4. 4. Neuroprotection and neurogenesis after experimental stroke

    Detta är en avhandling från Andreas Arvidsson, Section of Restorative Neurology, Wallenberg Neuroscience Center, BMC A-11, SE-221 84, Lund

    Författare :Andreas Arvidsson; Lund University.; Lunds universitet.; [2003]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; stereology; rat; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi; BrdU; immunohistochemistry; in situ hybridization; subventricular zone; striatum; dentate gyrus; neuronal replacement; neuronal survival; Focal cerebral ischemia; glial cell line-derived neurotrophic factor;

    Sammanfattning : In this thesis, two potential endogenous mechanisms for neuronal survival and repair have been investigated in a rat model of stroke, middle cerebral artery occlusion (MCAO): signaling of the GDNF family of neurotrophic factors, and neurogenesis from endogenous progenitor cells. As determined by in situ hybridization for GDNF family ligand and receptor genes, MCAO caused widespread upregulation of both components of the functional GDNF receptor, c-Ret and GFRalpha1, indicating that GDNF may be a survival signal in stroke.

  5. 5. Parietal cell regeneration in rat gastric mucosal wounds a quantitative light and electron microscopical study

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Håkan Blom; Umeå universitet.; [1982]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rat; gastric mucosa; gastric wounds; parietal cells; re­generation; pyloroplasty; truncal vagotomy; antrectomy; pen­tagastrin; cimetidine; carbacholine; stereology; light microscopy; electron microscopy; pH-studies;

    Sammanfattning : The aims of the study were to obtain a method with which it would be possible to produce standardized wounds in the gastric mucosa, and to follow the regeneration of the acid producing parietal cells in those lesions during different experimental conditions. Quantitative methods applied to light and electron microscopy were used. LÄS MER
