HO-1 activity. Quantification of the HO-1 levels was higher in the RIPC/LPS and LPS/RpostC compared with Saline group at 1 h after LPS or saline injection (p < 0.05). Mice were treated with saline (Saline group), RIPC plus saline (RIPC/Saline group), saline plus RpostC (Saline/RpostC group), LPS (20 mg/kg, i.p.; LPS group), RIPC plus LPS (RIPC/LPS group), and LPS plus RpostC (LPS/RpostC group). i.p.: intraperitoneal. RIPC: remote ischemic preconditioning, RpostC: remote ischemic postconditioning. Data are expressed as mean ± SEM (n = 6 in each group). *P < 0.05 versus LPS group. † P < 0.05 versus Saline.
