  1. 1. Blood Flow in Human Skeletal Muscle : The Effect of Adrenaline and the Influence of a Small Muscle Injury

    Författare :Torbjörn Vedung; Jan Henriksson; Jan Lundvall; Södersjukhuset Karolinska Institutet. Dept of Hand Surgery Dept of Physiology and Pharmacology; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adrenaline; blood flow; blood redistribution; ischemia; muscle injury; skeletal muscle; strain-gauge plethysmography; sympathetic tone; transmural pressure; 99mTechnetium clearance; tennis elbow; venous compliance; venous occlusion plethysmography; 133Xenon clearance; adrenaline;

    Sammanfattning : A variety of vasoregulatory systems are involved in the complex control of blood flow inhuman skeletal muscle. The interaction between these systems where one system canoverride or modify the other makes blood flow regulation complicated. LÄS MER

  4. 3. Non-invasive measurement of skeletal muscle blood flow using by photoplethysmography. Experimental studies on the human leg

    Författare :Qiuxia Zhang; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; photoplethysmography; skeletal muscle blood flow; perfusion pressure; intramuscular pressure; venous obstruction; muscle exercise; non-invasive; limb elevation; vibration exposure; hyperaemia; foot pump.;

    Sammanfattning : The purpose of this thesis was to validate a new non-invasive photoplethysmography (PPG) method for measuring relative changes in local muscle blood flow (MBF) in the human leg. Experimental conditions expected to impede or increase local MBF were used to test responsiveness of the PPG. LÄS MER

  5. 4. The regulation of muscle interstitial insulin, nutrients and blood flow in insulin resistant models. An investigation using the euglycemic insulin clamp and microdialysis techniques

    Författare :Maria Niklasson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; insulin resistance; skeletal muscle; glucose uptake; transcapillary transport; interstitial fluid; euglycemic insulinclamp; microdialysis; blood flow; vasodilation;

    Sammanfattning : Insulin resistance, mainly located to the skeletal muscle tissue, is one prominent feature in thedevelopment of non insulin-dependent diabetes mellitus (NIDDM) and further, associated withcardiovascular diseases. In this context the importance of blood flow for insulin sensitivity has beensuggested by regulating the delivery of insulin and nutrients to the target cells. LÄS MER

  7. 5. Microcirculation in skeletal muscle during hypoperfusion : An experimental study regarding some psysiological and pharmacological factors influencing blood flow and oxygen pressure distributions

    Författare :Urban Gustafsson; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The vascular bed in skeletal muscle plays an important role in the regulation of the systemic circulation. The present study was undertaken to investigate how capillary blood flow and oxygenation in skeletal muscle are affected by: a) a reduction in the levels of respiratory gases in blood, hypocapnia or hypoxia, and b) the interaction of anesthetics (pentobarbital, propofol, ketamine) during hemorrhage, and c) hypotension induced pharmacologically by adenosine, sodium nitroprusside or acetylcholine.
