1. 1. The hyperosmolar airway : Mechanisms of reduced response to nitric oxide

   Författare :Josephine Hjoberg; Uppsala universitet; []
   Nyckelord :Medical sciences; 8-Br-cyclic GMP; airway epithelium; airway reactivity; airway smooth muscle; amiloride; epithelium derived relaxing factor; furosemide; hyperosmolarity; hypertonic saline; nitric oxide; SNAP; sodium chloride; sodium nitroprusside; superoxide; tracheal perfusion; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Physiology; klinisk fysiologi;

   Sammanfattning : Inhaled nitric oxide (NO) relaxes smooth muscle of the airways and of pulmonary blood vessels and is used to treat lung diseases where the pulmonary vessels are constricted. NO has also been tested as a bronchodilator in asthmatic patients. LÄS MER

3. 2. Regulation of experimentally induced airway obstruction

   Författare :Eva G. Lindström; Jan Lötvall; Linköpings universitet; []
   Nyckelord :airway obstruction; antigen; capsaicin; epithelium; inflammatory mediators; sensory neurons; tube preparation; tachykinins; formoterol; histamine; presynaptic inhibition; in vitro; guinea pig; MEDICINE; MEDICIN;

   Sammanfattning : Asthma is one of the commonest diseases in industrialized countries. The cause and mechanisms of !he disorder are still not fully unden;tood, al!hough it is known that inflammation in !he airways plays an important role. Inflammatory mediators, e.g. LÄS MER

4. 3. Allergic airway disease : studies on diesel exhaust exposures, oxylipins and antioxidants

   Författare :Nirina Larsson; Annelie Behndig; Leif Bjermer; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Asthma; allergic rhinits; diesel exhaust; airway inflammation; oxylipins; metabolomics; antioxidants; SVCT2; bronchoscopy; lungmedicin; Lung Medicine;

   Sammanfattning : Allergic airway disease, i.e. allergic rhinitis (AR) and asthma, is a common health problem. The prevalence is increasing in most countries of the world. LÄS MER

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

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

   Sammanfattning : 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.

7. 5. Ultrastructural Studies of the Airway Epithelium in Airway Diseases

   Författare :Eyman Shebani; Godfried M. Roomans; Marie Johannesson; Anil Mehta; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Morphology; asthma; cilia; corticosteroids; cytokines; desmosomes; Gaucher’s disease; montelukast; primary ciliary dyskinesia; transmission electron microscopy; Morfologi; Morphology; cell biology; pathology; Morfologi; cellbiologi; patologi;

   Sammanfattning : Ultrastructural studies of airway epithelium in airway disease are important for diagnosis and understanding the underlying pathology which helps clinicians to improve the patients' treatment.Airway biopsies from a 5-month old boy with respiratory problems and gastro-oesophageal reflux were studied by transmission electron microscopy (TEM).
