Intestinal A1 blood flow. Group I = sham operation and no hemorrhagic shock (HS); Group II = HS + conventional resuscitation (CR) with the return of the shed blood + 2 volumes of normal saline (NS); Group III = HS + return of the shed blood + hypertonic saline (HTS) (7.5 % NaCl, 4 ml/kg); Group IV + HS + HTS (7.5 % NaCl, 4 ml/kg), then return of the shed blood after 60 min; Group V = HS + HTS (7.5 % NaCl, 4 ml/kg), then 1 volume of NS after 60 min. BL, baseline, RES, resuscitation; ↑, timing of initiation of second phase of resuscitation in Groups IV and V; §, P < 0.05 vs sham; * P < 0.05 vs CR (Group II) by 2-way ANOVA and Bonferroni post-test.
