  2. 11. Single fibre laser Doppler flowmetry for skeletal muscle perfusion measurements : methodological developments and clinical applications

    Author : Hongming Cai; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Measurements of microvascular blood flow in skeletal muscle by using the laser Doppler flowmetry (LDF) technique were first reported in 1979. The introduction of the single fibre technique in 1987 increased the possibilities of studying muscle perfusion under various physiological conditions without causing major tissue trauma. READ MORE

  4. 12. Nitric oxide production by the intestinal mucosa during hypoperfusion

    Author : Johan Snygg; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nitric oxide; nitric oxide synthase; intestinal epithelium; hemorrhagic shock; cardiac tamponade; septic shock; lower body negative pressure; splanchnic circulation; substrate; laser Doppler;

    Abstract : The present thesis is based on the concept that gastrointestinal blood hypoperfusion is a common phenomenon associated with critical illness. Furthermore, the development of the multiple organ dysfunction syndrome (MODS) is proposed to be initiated by gastrointestinal mucosal barrier dysfunction, allowing intestinal luminal contents to penetrate into the tissue and activate a systemic inflammatory response.

  5. 13. Assessment of microvascular function by use of transdermal iontophoresis : methodological aspects

    Author : Erik Droog Tesselaar; Folke Sjöberg; Angela Shore; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Iontophoresis; Microcirculation; Laser-Doppler; Acetylcholine; Sodium nitroprusside; Pharmacodynamics; Pharmacokinetics skin; Physiology and pharmacology; Fysiologi och farmakologi;

    Abstract : Assessment of the microcirculation is of major importance in understanding the physiology of the vasculature and in assessing te vascular effects of pathological conditions such as diabetes, hypertension and sepsis. Transdermal iontophoresis can be used to non‐invasively introduce vasoactive drugs into the skin. READ MORE

  6. 14. Rhinostereometry and laser doppler flowmetry : simultaneous measurements of inflammation and steroid effects in normal and allergic human nasal mucosa

    Author : Hans Grudemo; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Rhinastereometry; Laser Doppler Flowmetry; Nasal mucosa; Allergic rhinitis Histamine challenge;

    Abstract : This thesis describes the development of a combination of non-invasive methods for measuring different aspects of inflammation simultaneously in a selected part of the human nasal mucosa. It also describes use of this combination in studies of allergic nasal mucosa and the effects of intranasal steroids before and during the allergy season. READ MORE

  7. 15. Liver transplantation in man. Gastrointestinal perfusion and inflammatory response

    Author : Ebbe Rønholm; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; carbondioxide; complement activation; cytokines; endotoxaemia; hydrogen-ion concentration; liver transplantation; laser-Doppler flowmetry; PMN elastase; regional blood flow; reperfusion;

    Abstract : Patients undergoing liver transplantation develop a systemic inflammatory response which eventually continues with development of a multiple organ dysfunction syndrome (MODS). Gastro-intestinal hypoxia or bacterial translocation has been proposed as the "motor" of MODS. READ MORE
