  1. 1. Studies on Peripheral Nerve Regeneration: Microdispensing, Neurite Guidance and Galectins

    Author : Per Gustavsson; Funktionell zoologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; vävnadskultur; histokemi; cytokemi; Histologi; tissue culture; histochemistry; cytochemistry; Histology; Schwann cells; sciatic nerve; dorsal root ganglia; DRG; neurite guidance; galectins; inkjet; microdispensing; peripheral nervous system; nerve regeneration; Animal physiology; Djurfysiologi; Biotechnology; Bioteknik;

    Abstract : The present thesis describes development of a microdispenser-based technique to create of protein patterns for neurite guidance. The same technique was also developed to allow direct positioning of dissociated cells, including neurons, on cell culture substrates. Finally the role of galectin-3 and 8 during nerve regeneration was investigated. READ MORE

  2. 2. Phospholipase A2 in nerve injury and axonal outgrowth

    Author : Marie Hornfelt; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Neurology; cell death; apoptosis; leukotrienes; arachidonic acid; M-type receptor; secretory phospholipase A2; cytosolic phospholipase A2; sciatic nerve; dorsal root ganglia; growth cone; axonal outgrowth; nerve injury; peripheral nerve regeneration; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi; Animal physiology; Djurfysiologi;

    Abstract : This thesis deals with processes coupled to injury in the peripheral nervous system (PNS), with a general aim to investigate the role of phospholipase A2 (PLA2) enzymes in axonal outgrowth. The axonal outgrowth of dorsal root ganglia (DRG) neurons in vitro was reduced by several different inhibitors of PLA2 activity and enhanced by an activator of this enzyme. READ MORE

  3. 3. Repair and Reconstruction of Peripheral Nerve Injuries. Treatment with G-CSF and Stromal Vascular Fraction

    Author : Hanna Frost; Malmö Handkirurgi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; peripheral nerve injuries; nerve regeneration; reconstructive surgical procedures; diabetes mellitus; rat sciatic nerve; granulocyte colony-stimulating factor; stromal vascular fraction; electrospinning; rats; Schwann cells;

    Abstract : While surgery is a cornerstone in treatment of peripheral nerve injuries, it is not a comprehensive approach, and outcome is unsatisfactory, especially sensory function. The present aim was to translate recent findings about stem- and progenitor cells to improve regenerative outcome, where the cells have to be autologous, available within the same surgical procedure, and minimally manipulated.

  4. 4. Opioid-induced cholecystokinin release in the CNS-neurochemical mechanisms and effects of sciatic nerve lesion

    Author : Henrik Gustafsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Cholecystokinin (CCK) and opioid peptides have a similar distribution in the nervous system and CCK has been demonstrated to counteract opioid-induced analgesia at spinal and supraspinal level. An increased spinal release of CCK has been suggested to be a mechanism for the relative resistance to opioid analgesic drug in certain pain conditions following nerve lesions (i. READ MORE

  5. 5. Long acting local anaesthetics - a study in rats

    Author : Henrik Dyhre; Anestesiologi och intensivvård; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin människa och djur ; Medicine human and vertebrates ; in vivo and effect kinetics; Comparison of in vitro; Neuro toxicity; Infraorbital nerve block; Sciatic nerve block; Lipid depot formulation;

    Abstract : Local anaesthetics provide excellent pain relief after central and peripheral nerve blocks. However, in many clinical situations there is an insufficient duration of action to allow effective treatment of long-term pain with single injection techniques. This problem became the focus of the present studies. READ MORE
