A: Ethanol stimulation vs. total stimulation [ethanol+ forskolin (0.5%)] of transepithelial Cl− conductance (n = 9 per condition) indicates ethanol concentrations > 0.5% result in decreased total stimulation.
B: Ethanol (0.5%) significantly increased Cl− transport when compared to PBS control (n = 9; p<0.05). Total stimulated ΔISC following application of [ethanol (0.05%) + forskolin] were statistically different from those with [PBS + forskolin] (total stimulated ΔISC of ethanol + forskolin (n = 9) = 20.7 ± 1.2 μA/cm2; total stimulated ΔISC of PBS + forskolin (n = 4) = 13.0 ± 0.5 μA/cm2, p = 0.002). * Statistical significance (p < 0.05)
