to determine whether these peptidases play roles in modulating kinin-induced contractions in the airways , we studied the effects of captopril , an ace inhibitor , and of leucine-thiorphan and phosphoramidon , two nep inhibitors , on the contractile responses to bradykinin and lysyl-bradykinin in isolated segments of ferret trachea .
