摘要
目的:比较在传统心脏停搏液中加入L-精氨酸、L-精氨酸与腺苷和L-精氨酸、腺苷与组氨酸对心肌缺血/再灌注损伤的保护作用。方法:将60例法洛四联症婴幼儿随机分成3组,分别应用含L-精氨酸(A组)、L-精氨酸加腺苷(B组)和L-精氨酸、腺苷及组氨酸(C组)心脏停搏液灌注心脏。检测血清肌钙蛋白I(cTnI)、肌酸磷酸激酶同工酶(CKMB)含量。结果:B组血浆cTnI含量仅于主动脉开放2h显著降低(P<0.01),C组不但于主动脉开放后30min、2h和6h均显著低于A组(P<0.01或P<0.05),而且于主动脉开放2h、6h显著低于B组(P<0.01或P<0.05);C组血浆CKMB含量于主动脉开放后30min、2h、6h均显著低于A组(P<0.01或P<0.05),而在2h、6h也显著低于B组(P<0.01或P<0.05)。结论:加入L-精氨酸、腺苷和组氨酸心脏停搏液能显著减少cTnI、CK-MB的释放,较L-精氨酸和L-精氨酸与腺苷心脏停博液效果更好。
Objective:To compare the myocardial protective effect of three cardioplegic solution respecti- vely added L-- arginine, L--arginine and adenosine and L--arginine, adenosine and histidine in traditional cardioplegic solution. Methods: Sixty patients with tetralogy of Fallot were randomly divided into three groups, respectively,L-- arginine(group A), L-- arginine plus adenosine(group B) and L-- arginine, adenosine and histidine(group C). Serum level,s of troponin I(cTnI),creatine kinase isoenzyme(CKMB) content were tested in different time--point. Results: Plasma cTnI content in group B only significantly decreased (P〈0.01)2 h after opening aortic , group C plasma cTnI was significantly lower than that of group A(P〈0.01 or P〈0.05) not only in 30 rain,2 h and 6 h after opening aorta, but also significantly lower than those of group B after opening aortic: 2 h and 6 h(P〈0.01 or P〈0.05 ). Plasma content of CK- MB in group C were significantly lower than that in group A in 30 min,2 h and 6 h after opening aorta (P 〈0.01 or P〈0.05 ),and were significantly lower than that of group B (P〈0.01 or P〈0.05 ) in the 2 h and 6 h. Conclusion: L--arginine, adenosine and histidine cardioplegic solution can significantly reduce cT- nI, CKMB release,which has better effect thaa L--arginine and L--arginine and adenosine cardioplegic solution.
