摘  要:目的:通过在体兔心肌缺血再灌注模型,观察红花黄色素对家兔缺血再灌注心肌是否具有保护作用。方法:24只新西兰家兔随机分为缺血再灌注组(IR组)、缺血预处理组(IPC组)及红花黄色素组(SY组),每组8只。分别于结扎前、再灌注3h、再灌注6h采兔血,测定各组血超氧化物歧化酶(SOD)、丙二醛(MDA)、肌酸激酶同工酶(CK-MB)和肌钙蛋白I(cTNI)的水平。实验结束,用氯化硝基四氮唑蓝(NBT)染色测定心肌梗死面积。结果:与IR组相比,SY组和IPC组在再灌注各时间点MDA、CK-MB、cTNI浓度均降低(P<0.05),而SOD升高(P<0.05);SY组和IPC组坏死面积占总面积之比小于IR组(P<0.05)。结论:红花黄色素和缺血预处理一样能减轻缺血再灌注损伤。OBJECTIVE To study whether Safflor Yellow(SY) produces cardioprotection on rabbit cardiac ischemic-reperfusion model in vivo. METHODS 24 Rabbits were randomly distributed to three group(n = 8 in each group) :①Ischemia-reperfusion(IR) ;②Ischemic preconditioning(IPC) ;③Safflor Yellow (SY) . Each group was determined the density of serum superoxide dismutases(SOD), malonaldehyde (MDA), creatinkinase isoenzyme (CK-MB) and troponin Ⅰ (cTNⅠ) at three times: before LADO, reperfusion 3h and reperfusion 6h. The infarction sizes(IS) were measured with nitroblue tetrazolium(NBT) dye. RESULTS Compared with IR group, the levels of MDA ,CK-MB and cTNⅠ in SY group and IPC group were reduced significantly (P〈0. 05) at reperfusion 3h and reperfusion 6h, on the contrary, the levels of SOD was increased (P〈0. 05) ;The IS (percent age necrosis/total areas) was reduced significantly (P〈0. 05) in SY group and IPC group. CONCLUSION Safflor Yellow as same as ischemic preconditioning can protect the ischemia damage of myocardium.
