The ability of resveratrol or dimethyl sulfoxide (vehicle) to induce relaxation of human gallbladder muscle strips. Resveratrol-induced relaxation in the human gallbladder muscle fiber in a dose-dependent manner. The values are expressed as a percent of a papaverine (100 μM)-induced relaxation. The results given are from at least four experiments. The vertical bars represent ± standard error of the mean (SEM). * represents a significant difference compared with the relaxation induced by resveratrol (p < 0.05)
