Airway responsiveness to methacholine (Mch) in the absence of deep inspirations (DIs) is lower in athletes compared with sedentary individuals. In this prospective study, we tested the hypothesis that a training exercise program reduces the bronchoconstrictive effect of Mch. Ten healthy sedentary subjects (M/F: 3/7; mean + or - SD age: 22 + or - 3 yr) entered a 10-wk indoor rowing exercise prog...

bronchial asthma represents an increased airways responsiveness to vari¬ous stimulants, leading to reversible obstruction of expiratory flow and chronic inflammatory changes in airways wall. ketamine has been demonstrated to lower airway resistance and to increase lung compliance in the asthmatic patients. in several studies and case reports it has been used successfully in the management of st...
