  1. 1. Peripheral airway function in asthma and cystic fibrosis. Measurements using inert gas washout methods

    Författare :Henrik Ljungberg; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acinar; adults; airway hyperresponsiveness; asthma; children; conductive; functional residual capacity; gas trapping; inert gas washout; infants; peripheral airways; plethysmography; respiratory function tests; ventilation inhomogeneity;

    Sammanfattning : It is increasingly recognised that asthma and cystic fibrosis (CF) frequently involves the peripheral airways. Characteristic features of abnormal peripheral airway function are uneven ventilation distribution and increased gas trapping. LÄS MER

  3. 2. Nitric Oxide Exchange in Central and Peripheral Airways : Determinants in Health and Respiratory Disease

    Författare :Andrei Malinovschi; Christer Janson; Kjell Alving; Lena Holm; Elisabeth Bel; Uppsala universitet; []
    Nyckelord :exhaled nitric oxide; alveolar NO; bronchial NO flux; extended NO analysis; asthma; smoking; snus; IgE-sensitization; pharyngo-oral tract; nitrate; nitrite; pulmonary hypertension;

    Sammanfattning : Background: Exhaled nitric oxide (NO) is a marker of eosinophilic steroid-sensitive inflammation in the airways of patients with respiratory disease. Moreover, information about the localization of inflammation in the respiratory tree is obtained by estimates of bronchial and alveolar contributions to exhaled NO. LÄS MER

  4. 3. The asthmatic airway response – effects on physiology and biomarkers

    Författare :Henning Stenberg; allergologi och palliativ medicin Lungmedicin; []
    Nyckelord :Asthma; Exhaled breath temperature; Exercise; Allergen challenge; Small airways; Airway provocations; Spirometry; Impulse oscillometry; Inert gas washout; Body plethysmography; Club cell protein CC16 ;

    Sammanfattning : Asthma is a common airway inflammatory disease, associated with a variable degree of airway obstruction. It is a heterogeneous condition with large variations in severity and clinical presentation. Moreover, disease activity can vary from time to time. Taken together, these factors make the diagnosis, monitoring and treatment of asthma challenging. LÄS MER

  5. 4. From sneeze to wheeze: Non-invasive studies on asthma and rhinitis

    Författare :David Aronsson; allergologi och palliativ medicin Lungmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; airway inflammation; united airways; airway hyperresponsiveness; asthma; allergíc rhinitis;

    Sammanfattning : Asthma and allergic rhinitis are diseases that cause major disability and illness in all ethnic groups and ages. It is well established that allergic rhinitis and asthma are closely linked entities and more than 75 % of the patients with asthma reports concomitant rhinitis. LÄS MER

  7. 5. Nitric oxide and eicosanoids : significance and interactions during antigen-induced responses in peripheral lung tissue

    Författare :Anna-Karin Larsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Nitric oxide; leukotrienes; prostaglandins; histamine; ovalbumin; contractions; distal lung; rat; human; guinea pig; precision-cut lung slices; mast cell;

    Sammanfattning : Asthma means difficulty in breathing and is described as a chronic, inflammatory disorder that produces narrowing of the lower respiratory tract. The allergen-induced asthmatic bronchoconstriction is primarily caused by an IgE-mediated release of the mast cell mediators, histamine and eicosanoids (leukotrienes and prostanoids). LÄS MER
