  1. 1. Cell activation and nerve regeneration following peripheral nerve injury

    Författare :Annika Widerberg; Malmö Handkirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurology; nerve regeneration; Nerve injury; conditioning lesion; nerve graft; tourniquet compression; vibration; DRG; Schwann cell; p75; CPON; neurofysiologi; neuropsykologi; Neurologi; neurophysiology; neuropsychology;

    Sammanfattning : The effect of short time vibration exposure and tourniquet compression on nerve regeneration in rats was studied with special reference to cell activation. One of the hindlimbs was conditioned by either vibration exposure (5 hours / day - 5 consecutive days) or compression (150-300 mmHg for 30-120 minutes), which was followed by a recovery period of 0-7 days.

  3. 2. Surgery for ulnar nerve compression at the elbow : Focusing on factors influencing outcome

    Författare :Alice Giöstad; Erika Nyman; Lars Dahlin; Gustav Andersson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ulnar nerve compression; Simple decompression; Nerve transposition; PROM; Pain; Return to work; Spinal nerve root;

    Sammanfattning : Ulnar nerve compression at the elbow (UNE) is a common peripheral nerve compression disorder in the upper limb. The literature regarding surgical outcome is inconclusive. LÄS MER

  4. 3. PACAP and orphanin FQ/nociceptin -Distribution, importance and regulation in sensory neurons and spinal cord

    Författare :Lina Pettersson; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neurophysiology; Neurologi; neuropsykologi; neurofysiologi; neuropsychology; Neurology; trk; spinal cord; sensory neuron; rat; PAC1; PACAP; ORL1; OFQ N; neurotrophin; neuropeptide; nerve transection; nerve compression; inflammatory pain; BDNF; DRG;

    Sammanfattning : Neuropeptide expression in the nervous system is abundant and plastic, and an altered expression after injury is an example of a functional response, helping the neuron to cope with adverse changes, and involves effects on differentiation, synthesis, repair/regeneration, survival, and modulation of signal transmission. I have investigated the distribution/expression of the neuropeptides, orphanin FQ/nociceptin (OFQ/N) and pituitary adenylate cyclase activating polypeptide (PACAP), under normal conditions, in response to nerve injuries, and also studied sensory responses in mice deficient for the PAC1 receptor (PAC1-/-).

  5. 4. Effects of nucleus pulposus on nerve root circulation and function. Morphologic and functional studies in an experimental model using porcine spinal nerve roots

    Författare :Gunnar Byröd; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nerve root; dorsal root ganglion; intervertebral disc; nucleus pulposus; epidural space; nerve fibre; permeability; blood flow; sciatica;

    Sammanfattning : Sciatica due to lumbar disc herniation has for many decades been viewed as a consequence of mechanical compression exerted on spinal nerve roots by the bulging disc tissues. Recent research has, however, indicated that extruded nucleus pulposus (NP) from the intervertebral disc might cause functional and endoneurial morphological changes in spinal nerve roots, without mechanical compression.

  7. 5. Nerve tissue injury markers, inflammatory mechanisms and immunologic factors in lumbar disc herniation. Clinical and experimental studies

    Författare :Helena Brisby; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Disc herniation; sciatica; intervertebral disc; nucleus pulposus; nerve root; neurofilament; S-100; cytokines; nitric oxide; glycosphingolipids.;

    Sammanfattning : The general concept for sciatic pain has for many decades been mechanical nerve root compression caused by a herniated disc. Recently evidence has indicated a more complex process, with a combination of mechanical and inflammatory/immunologic factors involved. LÄS MER
