[The role of delayed rectifier potassium channels in the regulation of bronchial smooth muscle tension in asthmatic rats].

Abstract

OBJECTIVE To investigate the role of delayed rectifier potassium channels (K(V)) in the regulation of bronchial smooth muscle tension in asthmatic rats and their effects on bronchial reactivity in vitro. METHODS By using a specific potassium channel blocker, the bronchial contraction induced by spasmogens was observed in normal and asthmatic rats with the… (More)
