11. Single fibre laser Doppler flowmetry for skeletal muscle perfusion measurements : methodological developments and clinical applications
Sammanfattning : 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. LÄS MER
12. Nitric oxide production by the intestinal mucosa during hypoperfusion
Sammanfattning : 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.

13. Assessment of microvascular function by use of transdermal iontophoresis : methodological aspects
Sammanfattning : 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. LÄS MER
14. Rhinostereometry and laser doppler flowmetry : simultaneous measurements of inflammation and steroid effects in normal and allergic human nasal mucosa
Sammanfattning : 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. LÄS MER
15. Liver transplantation in man. Gastrointestinal perfusion and inflammatory response
Sammanfattning : 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. LÄS MER
