Figure 5From: The expression and relaxant effect of bitter taste receptors in human bronchiConcentration-response curves of (A) chloroquine, (B) phenanthroline, (C) dapsone and (D) flufenamic acid in human bronchi pretreated or not with 1 μM BAY K8644. The results are expressed as a percentage of the relaxation observed with 3 mM theophylline (mean ± SEM from 4 to 10 independent experiments). **p < 0.01.Back to article page
