1. 1. Peripheral nerve reconstruction. Studies on cellular and acellular iso-, allo- and xenografts

   Författare :Martin Kvist; Malmö Institutionen för kliniska vetenskaper; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acellular nerve graft; costimulation blockade; FK506; immunosuppression; nerve graft; nerve defect; nerve regeneration; nerve injury; nerve extraction; allograft; xenograft;

   Sammanfattning : The best results after a nerve injury with a defect are achieved by a nerve reconstruction procedure using autologous nerve grafts. However, limitations include insufficient amount of suitable donor material and donor site morbidity. The aim of the present thesis was to study alternative nerve grafts, i.e. LÄS MER

3. 2. 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.

4. 3. Sutures bridging nerve defects

   Författare :Peter Scherman; Malmö Handkirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; orthopaedics; traumatology; Surgery; continuous longitudinal sutures; nerve repair; nerve regeneration; nerve defect; Kirurgi; ortopedi; traumatologi;

   Sammanfattning : A new and simple method for the repair of nerve defects, in which sutures alone are used to guide regeneration between the nerve endings, was developed. Bilateral seven to 17 mm rat sciatic nerve defects were bridged by continuous longitudinal sutures with or without different modifications, by conventional autologous nerve grafts or direct repair under tension as controls.

5. 4. Stem cell transplantation and regeneration after dorsal root avulsion

   Författare :Carl Trolle; Elena Kozlova; Adam Reid; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Regeneration; dorsal root; sensory nerve; nerve injury; cell transplantation; Medical Science; Medicinsk vetenskap;

   Sammanfattning : Spinal root avulsion leads to paralysis and loss of sensory function. Surgical methods can improve motor function and ameliorate pain but sensory recovery in adults is poor. Previous studies have shown that cell transplantation or treatment with trophic factors can improve functional outcome in rodents after dorsal root transection or crush. LÄS MER

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

   Författare :Per Gustavsson; Funktionell zoologi; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER
