Effect of LEH and saline resuscitation on IFNγ signaling in the gut tissues of rats with hemorrhagic shock. Transcript levels of STAT1 (A), IRF1 (B), IFNGR1 (C), and IFNGR2 (D). The mRNA levels were determined in 4 samples per group. E: representative immunoblot showing the expression of phospho-STAT1 in gut tissue. F: densitometric ratio of phospho-STAT1 to total STAT1 expression (n = 3 per group). P < 0.05 vs. Ctrl*, HSϕ, and Salζ.
