Rats were subjected to moderate or severe hemorrhage and then resuscitated with either Ringer-saline (RS) or Ringer-lactate (RL). Electrolyte and hematocrit concentrations were measured before shock induction (baseline, T = 10 minutes), at the end of the experiment (sham group; shock/RS, shock/RL; T = 280 minutes) or at T = 150 minutes (that is, the last blood sample taken before the earliest death in the groups to be compared, shock/RS and shock/RL). The baseline values of the sham group were not significantly different from those of the other groups. Values are shown as the means ± SEM. *P <0.05 (vs. moderate shock/RS); # P <0.05 (vs. severe shock/RS).
