1. 有關airway hyperresponsiveness之轉機，何者有誤? (A) Increased contractility but not the volume of airway smooth muscle cells (B) Uncoupling of airway contraction as result of inflammatory changes in the airway wall (C) Loss of the maximum plateau of contraction fund in normal airways (D) Thickening of the airway wall by edema and structural changes amplifies airway narrowing
