cromolyn sodium, a mast cell stabilizing agent, provides an immediate protective effect against the exercise-induced bronchoconstriction while being used before the exercise. however, cromolyn is ineffective in reversing asthmatic bronchospasm; it is used as a maintenance therapy and has a prophylactic role in chronic asthma.    the purpose of this study was to determine the extent of change in...

airway mucus hypersecretion health effects caused by air pollutants may range from subtle biochemical or physiological signs, such as mildly reduced lung function, to difficult breathing, wheezing, coughing and exacerbation of existing respiratory conditions such as asthma. the aim of this study was measuring the adverse health effects of air pollution on lung function of primary school student...

previous literature has implicated that there might be an individual susceptibility difference in terms of race/ethnicity and gender in response to second hand smoke (shs) exposure. this study was done to examine the effect of shs exposure on lung function in non-smoking korean women.this cross-sectional study was conducted using the korea national health and nutrition examination survey (knhan...
