Effects of propofol preconditioning on GES‐1 cell viability under H/R conditions. (A) normoxic culture for 15 hours; H/R, hypoxia 3 hours/reoxygenation 12 hours; and propofol (1, 5, 10, 25, 50 and 100 μmol/L) preconditioning under hypoxia 3 hours/reoxygenation 12 hours. (B) Hypoxia (0.75, 1.5, 3, 6, 9 and 12 hours)/reoxygenation 12 hours, with propofol at 50 μmol/L. (C) Hypoxia 1.5 hours/reoxygenation (1, 2, 4, 6, 8 and 12 hours) with propofol at 50 μmol/L. (D) Normoxic culture (N) for 3.5 hours; H/R, fat emulsion 50 μmol/L preconditioning (F) and propofol 50 μmol/L preconditioning (P) groups subjected to hypoxia 1.5 hours/reoxygenation 2 hours. Means ± standard deviation, n = 6. *p < 0.05 vs. N group. # p < 0.05. ## p < 0.01 vs. H/R group.
