    Sammanfattning : Main objectives of this thesis were to evaluate a gamma scintigraphic method used to quantify drug aerosol deposition in the lung, to investigate the influence of two aerosol inhalation parameters on the distribution of inhaled dry powder within the airways, to assess pulmonary absorption kinetics and bioavailability of an inhaled hydrophilic solute in relation to site of deposition, and to assess the influence of a surface active agent (sodium taurocholate, a bile salt) on the deposition and absorption of an inhaled hydrophilic solute. Repeated planar gamma scintigraphy was found to provide the same information on total pulmonary drug deposition as an independent method that involved assessments of urinary drug recovery after blockage of gastrointestinal drug absorption when all of the critical parts of the methodological procedures were accurately and meticulously executed.

    Sammanfattning : The PET-CT imaging modality is based on positron emission tomography combined with computed tomography. Before a PET-CT examination, a radioactive tracer (also called a radiopharmaceutical) is intravenously injected into the patient. PET technology images the distribution of this tracer element by detecting the decay. LÄS MER

    Sammanfattning : Bildtagning med magnetresonans (mangetic resonance imaging eller MRI) är en fascinerande teknik som använder magnetfält och radiovågor för att skapa detaljerade bilder av kroppens innanmäte. Tvärt om mot vad många tror så finns det ingen ”magnetröntgen” i MR-kameran, och därmed ingen skadlig joniserande strålning. LÄS MER

    Sammanfattning : In this thesis we explore and further develop several techniques used in the animal laboratory as well as in the clinical setting. In particular, we expand the understanding and usefulness of plethysmographic techniques in small rodents. LÄS MER

  5. 5. Arterial wall stiffness in man. On gender differences and abnormalities in insulin dependent diabetes mellitus and alpha1-antitrypsin deficiency

    Författare :Åsa Rydén Ahlgren; Malmö Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sex characteristics.; abdominal aortic aneurysm; arterial stiffness; alpha1-antitrypsin deficiency; ultrasonography; Insulin dependent diabetes mellitus; Clinical physics; radiology; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Sammanfattning : The mechanical properties of major arteries may reflect early manifestations of vascular disease and are also of interest because they are important for cardiac work. Using echo-tracking sonography and blood pressure measurements, arterial stiffness and diameters were investigated in healthy individuals as well as in patients with insulin dependent diabetes mellitus (IDDM) or alpha1-antitrypsin deficiency (alpha1-AT deficiency).
