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. Peripheral nerve function : metabolic features, clinical assessment, and heat shock protein 27

   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Peripheral neuropathy is a common complication among patients with diabetes mellitus, but whether peripheral neuropathy is present in individuals with impaired glucose tolerance (IGT) is debatable. In order to identify and diagnose peripheral neuropathy correctly, it is important to evaluate diagnostic tools that can be implemented in routine health care to assess both large and small nerve fibre function.

4. 3. 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.

5. 4. 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.

7. 5. Development of biosynthetic conduits for peripheral nerve repair

   Författare :Aleksandra McGrath; Liudmila N Novikova; John Haycock; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biosynthetic conduit; Mesenchymal stem cells; Nerve graft; Nerve tissue engineering; Peripheral nerve injury; Schwann cells;

   Sammanfattning : Peripheral nerve injuries are often associated with significant loss of nervous tissue leading to poor restoration of function following repair of injured nerves. Although the injury gap could be bridged by autologous nerve graft, the limited access to donor material and additional morbidity such as loss of sensation and scarring have prompted a search for biosynthetic nerve transplants.
