Fig. 2. Effect of stress on AHR measured in OVA-sensitized and airway-challenged CBA/J mice. Indicated are mean and SEM from stressed (N = 8) and nonstressed (N = 8) sensitized CBA/J mice. The frequency that caused 50% of maximal contraction (ES₅₀) was calculated. Airway contractility is expressed as percent of nonstressed control (2.1 Hz). * p < .05.
