Figure 7From: Effects of guaifenesin, N-acetylcysteine, and ambroxol on MUC5AC and mucociliary transport in primary differentiated human tracheal-bronchial cellsEffects of guaifenesin (GGE), N -acetylcysteine (NAC) or ambroxol (Amb) on rheological parameters. G’ (elasticity) and G” (viscosity) of the secretions from human primary lung epithelial cell cultures at 24 hr are shown. Elasticity and viscosity of collected, undiluted, apical secretions were evaluated using a 20 mm parallel plate rheometer at a 50 μM gap size. ** and *** indicate p < 0.01 and 0.005, respectively, vs. the IL-13-only control (ANOVA with Dunnett’s post-test).Back to article page
