作者观察到大鼠失血性休克早期各脏器（小肠、肺、肝）ＭＤＡ含量变化不显著，甚或有减少（心、肾）；回输血后除肺外，其它脏器ＭＤＡ含量均显著增加。心、肝、肾组织ＡＴＰ及能荷回输血后仍低于对照组；ＳＯＤ、ＣＡＴ预处理后各脏器ＭＤＡ含量均显著减少，心、肝、行组织ＡＴＰ、能荷显著升高。结果提示：失血性休克回输血后多个器官组织氧自由基产生增加，能量代谢恢复亦发生障碍。ＳＯＤ、ＣＡＴ治疗可降低组织脂质过氧化反应，促进能量代谢的恢复。 The authors observed that there was no significant or even decreased MDA content in various organs (small intestine, lung, and liver) at the early stage of hemorrhagic shock in rats, and MDA levels in other organs were significantly increased after blood transfusion. The content of ATP in heart, liver and kidney tissue was still lower than that in the control group after ATP was transfused; the content of MDA in each organ was significantly decreased after SOD and CAT pretreatment; The results suggest that the oxygen free radical production in multiple organs and tissues after hemorrhagic shock is transfused and energy metabolism is also impaired. SOD, CAT treatment can reduce tissue lipid peroxidation and promote energy metabolism recovery.
