CpG-ODN was intraperitoneally administrated 1 hour before trauma-hemorrhage (T-H). Hemodynamic parameters were measured “Before” (before hemorrhage), “During” (during the first 10 minutes of hemorrhage, the mean AP was maintained at 35±5 mmHg) and “After” (at 60 minutes after the initiation of hemorrhage). Sham control was subjected to the same procedures as T-H group, but without bleeding. HR: heart rate; LVDP: left ventricular developed pressure (left ventricular systolic pressure- left ventricular diastolic pressure); SV: stroke volume; CO: cardiac output; SW: stroke work; dP/dtmax: maximum value of dP/dt; Mean AP: mean arterial pressure. Results are presented as mean ± SEM (N = 5–8/group). ,
P < 0.05 compared to corresponding “Before”;
P < 0.05 Vehicle T-H vs. Vehicle sham;
P < 0.05 CpG T-H vs. Vehicle T-H.
