Abstract:

Exhaled breath condensate (EBC) is a non-invasive method of investigating airway inflammation associated with nitric oxide (NO) and the metabolites nitrite/nitrates (NOx) in diseases such as chronic obstructive pulmonary disease (COPD), but some of the variables affecting the results are unknown. It was hypothesised that 1) EBC would be influenced by lung volumes and the type of EBC collection device; 2) fractional exhaled NO (FENO) and EBC NOx in COPD patients would be altered by smoking and glucocorticosteroids (GCS); 3) cigarette smoke could contribute to the EBC NOx concentration while it

Abstract:

Measuring the level of exhaled NO (eNO) in the breath is a new method to monitor airway inflammation in asthma and may have a role in the management of asthma. The hypotheses were that eNO will reflect the degree of inflammation in chronic asthma, and will indicate how anti- inflammatory therapy should be altered to improve asthma control. Three studies were performed to test the hypotheses. A cross sectional study was performed to define the normal range of eNO and to compare this range with those who have asthma or atopy. The second study was observational, to compare the level of eNO during

Abstract:

Chronic obstructive pulmonary disease (COPD), a progressive and nonreversible disease, is a leading cause of mortality and morbidity throughout the world. Detecting COPD early in the disease process will help in decreasing later stage COPD severity. Because airway inflammation is a hallmark of COPD, it has been proposed that measuring exhaled nitric oxide, a marker of inflammation, in exhaled breath condensate could prove to be an inexpensive and efficient method to detect COPD in outpatient settings. Using the hypothetico-deductive theory as a guideline, this study used secondary data from th

Abstract:

Introduction: The enzyme, inducible nitric oxide synthase (iNOS), is upregulated in the airway epithelium in patients with allergic asthma resulting increased nitric oxide production. The concentration of nitric oxide in exhaled air (FENO) correlates with the degree of eosinophilic airway inflammation and has been proposed as a new breath test to assist in the management of asthma. Key Aims: To determine the predictive accuracy of FENO compared with conventional testing in the diagnosis of asthma. To assess the performance characteristics of FENO to predict steroid responsiveness compared

Abstract:

Air pollution in the home has been associated with asthma and asthma-like symptoms in children. To understand how they contribute to the initiation and/or exacerbation of asthma, the toxic effects of these pollutants on the human respiratory system have been studied under controlled laboratory conditions. In these clinical studies exposure is short and concentrations are generally higher than those encountered on a daily basis. Domestic levels of air pollutants are quite low and little is known about how chronic exposure to these low level pollutants can affect asthma prevalence and severity.

Abstract:

The air that humans exhale contains various chemical markers whose levels have been associated with various respiratory disorders. Therefore, measurement of these markers offers a potential method of examining airway disease status. Furthermore, exhaled breath offers the advantage of being easy to collect and non-invasive. Hence, these exhaled breath markers are potentially of significant clinical use in examining airways. Therefore, examination of exhaled breath has become the subject of intense study.

This thesis is the first to demonstrate the most appropriate spirometry and FeNO reference values for use amongst Aboriginal and Torres Strait Islander children and young adults. Availability of this data will lead to improved accuracy of spirometry and FeNO interpretation which will aid in more timely diagnosis and management of respiratory conditions for this population. Results from this study also suggest that healthy Australian Indigenous lung function data may not be as low as previously reported in earlier studies.

碩士<br>輔仁大學<br>公共衛生學系碩士班<br>96<br>Background： According to the epidemiological studies, it demonstrated that the prevalence and incidence rate of asthma were increasing gradually every year. People spent over 80 % of their time indoors. Indoor and outdoor air pollutants such as particular matter（PM）, volatile organic compounds（VOCs）, sulfur dioxide（SO2）, ozone（O3）had been proved to be significantly correlated with the increased incidence of respiratory symptoms in asthmatic children. Collection of exhaled gas was a simple and noninvasive technique for sampling of nitric oxide（NO）and air

碩士<br>中國文化大學<br>應用化學研究所<br>87<br>Nitric oxide (NO) can be detected in the exhaled air of humans. Several recent studies have demonstrated that the concentration of exhaled NO is increased in patients with asthma, but reduced after patients were treated with inhaled glucocorticoids. In this thesis, we would like to build up a data bank and a method for measurement of exhaled NO concentrations of asthmatic patients in Taiwan. Exhaled NO determinations were performed via a on-line restricted exhaled breath method in 57 normal and 82 asthmatic subjects by a chemiluminescence analyzer. T

博士<br>中山醫學大學<br>醫學研究所<br>101<br>Objective: To evaluation the usefulness of FeNO measurement in patients with eosinophilic inflammatory airway disease, such as bronchial asthma and chronic cough. Material and Method: A nitric oxide analyzer (NOA 280i) was used to conduct five experiments. In the first experiment, 249 Taiwanese non-smoking healthy adults were enrolled to determine the reference values of FeNO in Taiwan. In the second experiment, the correlations between offline and online FeNO data of 56 patients were evaluated. In the third experiment, the correlations between FeNO level and %

Abstract:

Introduction: People with asthma suffer from lower fitness levels when compared to their peers. The abnormal respiratory response to exercise, known as exercise induced bronchoconstriction (EIB), in the majority of people with asthma is a barrier to improving fitness levels. EIB severity can be increased with airway inflammation, which can be measured by exhaled nitric oxide (eNO). One exercise protocol, high intensity interval exercise (HIIE), may decrease the risk of developing EIB in people with asthma. HIIE warm up studies have demonstrated that HIIE is feasible and reduces the incidence o
