The effect of saline (a and c) or CP-99994 (b and d) on cumulative concentration-response curves for SP and frequency-response curves for EFS in isolated mice tracheal smooth muscle after exposure to 5 days FA (open circles) or SS-(solid circles). Values are means SE; in each group. *Significant difference in EFS between FA and SS exposure, .
