Translational inhibitor (cycloheximide) effect on DSP led to changes in ET-1 and S6c contractility. Rat bronchial segments were incubated for 24 hours in DSP in two groups. In the one group a translational inhibitor (cycloheximide, 10 μg mL-1) was added. Two-way Anova with Bonferroni post test was used to compare contraction at different concentrations of agonist. * P < 0.05.
