1. 6. Endogenous Nitric Oxide Production and Pulmonary Blood Flow : during different experimental lung conditions

   Författare :Manja Nilsson; Filip Fredén; Kristina Hambraeus-Jonzon; Göran Hedenstierna; Eddie Weitzberg; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nitric oxide; pulmonary blood flow; endotoxin; nitric oxide inhalation; endothelin; hypercapnia; acidosis; lavage-induced lung injury; Anaesthetics and intensive care; Anestesiologi och intensivvård; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

   Sammanfattning : Nitric oxide (NO) is an important regulator of pulmonary blood flow and attenuates hypoxic pulmonary vasoconstriction (HPV). Nitric oxide is synthesized enzymatically in a number of tissues, including the lungs, and can also be generated from reduction of nitrite during hypoxia and acidosis. LÄS MER

3. 7. T cells in chronic obstructive pulmonary disease

   Författare :Ester Roos-Engstrand; Anders Blomberg; Anders Bucht; Annelie F Behndig; Magnus Sköld; Claes-Göran Löfdahl; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; airway epithelium; bronchoscopy; bronchoalveolar lavage; endobronchial mucosal biopsies; inflammation; flow cytometry; T lymphocytes; CD25; CD127; FoxP3; Lung diseases; Lungsjukdomar; lungmedicin; Lung Medicine;

   Sammanfattning : Background: Tobacco smoking is the main cause of chronic obstructive pulmonary disease, COPD, but the mechanisms by which cigarette smoke induces COPD are still elusive. T lymphocytes have been implicated in the pathogenesis of the disease, but their role in the airway inflammation in COPD is not fully understood. LÄS MER

4. 8. Airway inflammation in "healthy" smokers. Relation to lung function and high resolution CT findings

   Författare :Ann Ekberg-Jansson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chronic obstructive pulmonary disease; smoking; bronchoalveolar lavage; bronchial biopsies; cytokines; lymphocytes; computed tomography; lung function; respiratory symptoms;

   Sammanfattning : The aim of the present study was to characterize the inflammatory pattern in "healthy"smokers and relate it to lung function, high resolution computed tomography (HRCT) findings and respiratory symptoms in order to identify smokers at risk to develop COPD. Subjects were recruited from a population study "Men born 1933 in Göteborg". LÄS MER

5. 9. Recruitment of small size lungs - experimental studies

   Författare :Angela Hanson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; lung recruitment; PEEP titration; VTCO2; Cdyn; computed tomography; cardiac output; atelectasis; lung aeration; driving pressure;

   Sammanfattning : Background: Patients - both children and adults - undergoing anesthesia and mechanical ventilation rapidly develop atelectasis. Even more severe problems occur in patients with acute lung injury/acute respiratory distress syndrome. LÄS MER

7. 10. Ozone and diesel exhaust : airway signaling, inflammation and pollutant interactions

   Författare :Jenny Bosson; Anders Blomberg; Thomas Sandström; Ellinor Ädelroth; John Balmes; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; air pollution; ozone; diesel exhaust; airway inflammation; asthma; immunohistochemistry; Lung diseases; Lungsjukdomar; lungmedicin; Lung Medicine;

   Sammanfattning : It is well established that air pollution has detrimental effects on both human health as well as the environment. Exposure to ozone and particulate matter pollution, is associated with an increase in cardiopulmonary mortality and morbidity. Asthmatics, elderly and children have been indicated as especially sensitive groups. LÄS MER
