in nine patients with asthma and 11 normal subjects , by means of specific airway conductance ( gaw/vl ) and flow volume loops , we measured : resting airway caliber , bronchodilation after 0.75 and 1.50 mg of quantitatively inhaled atropine ( a0.75 and a1.50 ) , provocation dose-40 of acetylcholine ( ach ) ( pd40-ach ) , dose ratio of ach ( dr-ach ) after saline solution , a0.75 and a1.50 , and the slope of log-dose response curves to ach ( sldrc-ach ) .
