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...
1. The relationship between volumes expired and the maximum intrathoracic pressures developed within the first second of expiration was examined in a group of healthy subjects and patients with airways obstruction who exhaled with varying degrees of effort. 2. The body plethysmographic method was used to ensure that expirations started from total lung capacity. 3. Three different types of volum...
Numerous epidemiological surveys have tried to evaluate the effects of exposures relevant to pulmonary disease.' A number of studies have analysed forced expiratory volume in one second (FEVI) using linear regression analysis, thus enabling adjustment for age, height, and sex as well as potential confounding variables. Within the last few years, studies analysing dichotomous FEV, variables with...
