1. 1. Laser Doppler Perfusion Monitoring and Imaging especially as regards testing for sympathetic nerve function

   Författare :Carolin Freccero; Kirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; wavelength; sympathetic vasodilatation; sympathetic vasoconstriction; sympathetic nerve function; parasympathetic nerve function; laser Doppler perfusion imaging; laser Doppler perfusion monitoring; finger skin blood flow; fibre separation; contralateral cooling; Concentration; Fysiologi; Cardiovascular system; Kardiovaskulära systemet; Diagnostik; Diagnostics;

   Sammanfattning : The operating principle of all laser Doppler methods is based on the fact that incident photons shift in wavelength when interacting with moving blood cells passing through the microvascular network. After photodetection and further signal processing, the recorded parameter can be considered an arbitrary measure of tissue blood flow, and this is referred to as ?perfusion?. LÄS MER

3. 2. Studies of sympathetic nerve activity in cutaneous nerves in healthy subjects using intraneural microneurography : The relationship between nerve activity and effector organ response

   Författare :Pirkko Hynninen; Anna Rostedt Punga; Roland Flink; Kristin Ørstavik; Uppsala universitet; []
   Nyckelord :Human; microneurography; neurophysiology; sympathetic nerve activity;

   Sammanfattning : The aim of the research presented in this thesis is to gain new knowledge of the characteristic features of sympathetic nerve activity of cutaneous nerves in healthy adult humans using intraneural microneurography. One further goal is to study the relationship between nerve activity and effector organ response. LÄS MER

4. 3. Structure and function of trigeminal primary sensory neurons after peripheral nerve injury

   Författare :Ulf Bongenhielm; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :ankyrinG; chronic constriction injury; electron microscopy; electrophysiology; hyperexcitability; immunocytochemistry; inferior alveolar nerve; in situ hybridisation; nerve injury; neuroma; SNS PN3; sodium channel; trigeminal ganglion;

   Sammanfattning : Iatrogenic injuries to branches of the trigeminal nerve are common during surgical procedures in the jaws and teeth, and as the repercussion of facial fractures or certain pathologies. A portion of these patients are left with disturbed sensory functions, and some with unpleasant abnormal sensations, including pain. LÄS MER

5. 4. Ganglionic nerve fibres in ventral roots

   Författare :Magnus Karlsson; Mårten Risling; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : According to the law of Magendie, the ventral roots channel efferent nerve fibres from the spinal cord to the periphery, while the dorsal roots channel afferent axons from the periphery into the spinal cord. However, as sensory C-fibres have been observed in mammalian ventral roots outside the autonomic outflow, this law has been questioned. LÄS MER

7. 5. Facial nerve injury and microsurgical repair : Experimental and clinical studies

   Författare :Davor Jergovic; Thomas Carlstedt; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Facial palsy is a relatively common clinical condition with a variety of causes. Irrespective of its etiology, facial palsy always represents a very serious problem for the patient. This underlines the need for more effective treatment procedures. LÄS MER
