Abstract:
Objective To test the protective effect of a new Ringer's malate solution on intestine's apoptosis caused by hemorrhagic shock in rats.Methods Forty-eight Sprague-Dawley male rats, weighing 280-320 g, were randomly assigned into four groups: sham shock group (group SS), normal saline group (group NS), Ringer's lactate group (group RL) and Ringer's malate (group RM), n=12 each.The group SS was served as control group, the other groups were subjected to 60 min of hemorrhagic shock followed by crystalloid resuscitation.Those rats were sacrificed 3 h after resuscitation.Intestinal tissue was harvested to detect Bcl-2/Bax protein level, the bioactivity of superoxide dismutase (SOD) and malondialdehyde (MDA) level.The level of intestinal cell apotosis was measured using TUNEL method and apoptosis index was calculated.The intestinal histopathology was examined.Results Compared with group SS, the expression of Bcl-2 and the bioactivity of SOD were lower, the level of Bax protein, MDA and apoptotic index were higher in groups NS, RL and RM (P<0.05).Compared with groups NS and RL, the expression of Bcl-2 and the bioactivity of SOD was higher, the level of Bax protein, MDA and apoptotic index were lower in group RM (P<0.05).Histopathological examination showed that group RM was better than group NS and group RL.Conclusion Ringer's malate alleviated intestinal apoptosis caused by hemorrhagic shock in rats.The study suggests that Ringer's malate solution could be a potential new therapeutic agent for fluid resuscitation.
