Protection of ghrelin postconditioning on hypoxia/reoxygenation in gastric epithelial cells

Figure 1 Effects of different doses of ghrelin on cell viability in human gastric epithelial cells induced by H/R. Cells were grouped as follows: normoxic culture for 6 h (N), 2 h hypoxia/4 h reoxygenation (H/R), alcohol vehicle postconditioning (DM) and ghrelin postconditioning at three doses (10^-9 mol/L, 10^-8 mol/L and 10^-7 mol/L). Cell viability was detected by 3-(4,5-dimethylthazol-2-yl)-2,5-diphenyl tetrazolium bromide assay. mean ± SD. n = 6. ^aP < 0.05, ^bP < 0.01 vs H/R.
