  2. 1. Airway responsiveness and exhaled nitric oxide : Studies in asthma and Sjögren's syndrome

    Author : Dóra Lúðvíksdóttir; Uppsala universitet; []
    Keywords : Medical sciences; Airway hyperresponsiveness; nitric oxide; airway inflammation; Sjögren s syndrome; asthma; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

    Abstract : In this thesis, four different types of provocation agents: methacholine, adenosine, cold air and mannitol were used to study different aspects of the airway responsiveness profile in asthma and Sjögren's syndrome. Exhaled nitric oxide (NO) and markers of eosinophil activation, serum eosinophil peroxidase (S-EPO) and eosinophil cationic protein (S-ECP) were measured. READ MORE

  4. 2. Nitric oxide within the concept of united airway disease : Exhaled and nasal nitric oxide in cystic fibrosis, asthma and upper airway inflammatory diseases

    Author : Christina Krantz; Andrei Malinovschi; Kjell Alving; Celeste Porsbjerg; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nitric oxide; nasal NO; exhaled NO; asthma; cystic fibrosis; airway inflammation; upper airway inflammatory disorders; united airway disease; IgE sensitisation; Lungmedicin; Lung Medicine; Pediatrik; Pediatrics;

    Abstract : Background: Within the concept of united airway disease, it is postulated that inflammatory disorders in the upper and lower airways are interrelated and influence each other. Fractional exhaled nitric oxide (FeNO) is an established biomarker of type-2 inflammation in the lower airways and is elevated in patients with asthma. READ MORE

  5. 3. Airway effects of diesel exhaust in healthy and asthmatic subjects

    Author : Charlotta Nordenhäll; Thomas Sandström; Ellinor Ädelroth; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; air pollution; diesel exhaust; airway responsiveness; airway inflammation; lung function; asthmatics; immunohistochemistry; bronchial epithelium;

    Abstract : Several epidemiological studies have revealed an association between particulate matter (PM) pollution and various health effects. Importantly, there is evidence to suggest that individuals with pre-existing respiratory disease, such as asthma, are more sensitive to elevated ground levels of particulate matter as compared to healthy subjects.

  6. 4. Innate defense mechanisms of the nasal airway

    Author : Henrik Widegren; Lund näs- och halssjukdomar Öron-; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neutrophils; Leukotriene B4; CC10; TNF-alpha; innate immunity; allergic rhinitis; Airway inflammation;

    Abstract : Allergic and infectious rhinitis are prevalent conditions that besides a direct morbidity also causes exacerbations of asthma and chronic obstructive pulmonary disease. The immune mechanisms associated with various forms of rhinitis are not fully understood. READ MORE

  7. 5. Effects of nitrogen dioxide on airway responsiveness in allergic asthma

    Author : Victoria Strand; Karolinska Institutet; Karolinska Institutet; []
    Keywords : air pollution; nitrogen dioxide; asthma; allergy; airway responsiveness; pulmonary function; eosinophils; particulates; repeated exposure;

    Abstract : Asthma is one of the most common chronic diseases in the industrialized world and its prevalence is increasing. Clinical symptoms of airway obstruction and bronchial hyper responsiveness can be induced by specific agents, such as allergens and non-specific stimuli, such as cold air and irritants. READ MORE
