丹参注射液在急性心肌梗死溶栓治疗中抗过氧化损伤的实验研究

目的　研究探讨丹参注射液在急性心肌梗死溶栓治疗中抗过氧化损伤作用。方法　采用电刺激家兔冠脉形成急性心肌梗死模型 ,研究观测体表心电图、整体心肌功能指标、血清和心肌梗死组织脂质过氧化损伤的生化指标和病理指标。结果　尿激酶联合丹参注射液溶栓治疗 ,可明显减轻或避免尿激酶溶栓治疗引发的再灌注心律失常、心肌收缩力和心输出量的下降、血清心肌损伤酶学的升高及心肌脂质过氧化损伤程度。结论　丹参注射液在急性心肌梗死家兔尿激酶溶栓治疗中可以明显减轻或避免心肌过氧化损伤。

The experiment study of injectio tanshin on the antiperoxide damage during dissolving thrombus to cure the acute myocardial infarction

AIM To study the antiperoxide damage of injectio tanshin during dissolving thrombus to cure the acute myocardial infarction(AMI). METHODS AMI model formatted by electricity to irritate the left ventricular branch of coronary artery of open-chest rabbit,and observation aspects including electrocardiogram(ECG),cardiac output and contractility,serumal enzymatic activities and biochemistry and pathology of lipid peroxide extent of myocardial infarction zone. RESULTS By urinate kinase(UK) combining with injection tanshin,abnormal changes of ECG, descending of cardiac contractiles and cardiac output,going up of serum cardiac damage enzyme(CPK-MB and LDH),and the malondialdehyde(MDA)of serum and myocardial infarction zone could be remarkably reduced or avoided during UK dissolving the thrombus to cure AMI rabbits. CONCLUSION Injection tanshin can clearly reduce or avoid lipid peroxidation damage during UK dissolving the thrombus to cure the acute myocardial infarction.
