摘要: 目的 探讨骨髓间充质干细胞(MSCs)对急性心梗的大鼠心肌组织中能量代谢关键酶的影响。方法 SD大鼠18只,随机分为假手术对照组、急性心梗组及MSCs移植组。应用ELISA检测大鼠左心室组织中己糖激酶(HK)、肉毒碱脂酰转移酶(CACT)、脂酰辅酶A合成酶(ACS)、柠檬酸合成酶(CS)和乳酸脱氢酶(LDH)的含量及活性。结果 大鼠心梗后1d左心室组织中CACT、ACS、CS和LDH的含量下降、HK的含量和活力增加(P<0.05或P<0.01)。在经过MSCs移植后上述酶的水平基本恢复。结论 急性心梗后左心室组织能量代谢的关键酶发生变化,MSCs移植对这种能量代谢的异常变化具有一定的改善作用。

Abstract: Objective To investigate the effects of transplantation of MSCs on the key enzymes of energy metabolism after acute myocardial infarction(AMI). Methods Eighteen SD rats were randomly divided into 3 groups(n=6 respectively):control group,acute myocardial infarction group,MSCs group. The left ventricular tissues of rats were isolated one day later after left anterior descending artery occlusion for determination of HK, CACT,ACS,CS,LDH by ELISA. Result One day post-AMI,the concentration and activity of these enzymes changed obviously(P<0.05~P<0.01). One day after MSCs treatment post-AMI,some of concentration and activity of those enzymes had returned to normal levels. Conclusion The transplantation of MSCs may improve cadiocyte's energetics by regulating the concentration and activity of those key enzymes .
