Mean arterial pressure and survival time of rats subjected to hemorrhagic shock and reperfusion. (a) Survival analysis was assessed with the Kaplan-Meier method and log-rank tests ( rats per group). (b) Time course of MAP during 120 minutes of hemorrhagic shock followed by 120 minutes of observation ( rats per group). compared with the control group; compared with the vehicle group; , compared with the PD group. BL, baseline; DA: drug administration; H, hemorrhage; R, reinfusion; PR, postreinfusion; PD, polydatin.
