The afferent responses of CSLV fibers to the right atrial bolus injection of capsaicin (A) and to lung inflation (B) before and 5, 15, 30, 60, and 90 min after the termination of airway exposure to aerosolized l-cysteine (5 mg/ml for 3 min) in 2 groups of rats. ^aSignificantly different from the value before inhalation in the same group (P < 0.05). *Significantly different from the value at the corresponding time period in the vehicle group (P < 0.05). Data in each group are means ± SE of 8 fibers recorded from 8 rats. See Fig. 2 for further explanation.
