Effects of SP600125 and nicaridipine on the sodium fluoride (NaF)- and calyculin-A-induced contraction of bronchial rings isolated from rats. Typical traces of the effects of vehicle (A), SP600125 (B), and nicardipine (C) on NaF- or calyculin-A-induced contraction in bronchial smooth muscle. SP600125 (30 μM) and nicardipine (1 μM) were added 30 min before the addition of NaF or calyculin-A. Values are the means ± SEM from four independent experiments, respectively (D, E). **P < 0.01 vs. Vehicle (DMSO).
