Cell viability of RGM 1 cells. (a) The time course of RGM 1 cell incubation in the acidic medium to induce cell damage. Cells were cultured in normal medium (pH 7.4) for 2 h and acidic medium (pH 4.0). (b) RGM 1 cells were pretreated with 100 μL of various concentrations (0.1, 1, 2, 5, and 10 mg/mL) of Magnolia officinalis water extract or sucralfate (3 mg/mL) as the positive control and cultured in normal medium for 2 h and acidic medium for 40 min. Data are presented as a relative percentage versus the mean of the control group (100%) and the mean ± S.E. from three independent experiments. ^∗ vs. negative control.
