Effect of saline and LEH resuscitation on the ER stress in the gut tissue of rats with hemorrhagic shock. Messenger RNA levels of spliced (s)XBP1 (A), total (t)XBP1 (B), spliced XBP1/total XBP1 ratio (C), GRP78 (D), GRP94 (E), ATF4 (F), CHOP (G), and GADD34 (H). The data are from at least 4 tissues from different animals per group. P < 0.05 vs. Ctrl*, HSϕ, and Salζ.
