摘要
目的通过建立心肌梗死大鼠模型,进而且分子生物学手段检测心肌Egr-1和NF-κB的表达,以期为心梗医学鉴定提供更多的数据和更好的方法。方法 (1)通过手术建立心肌梗死大鼠模型;(2)应用半定量PCR和免疫组织化学法检测心肌组织内Egr-1的表达;(3)半定量PCR方法和weatern blotting检测p65表达。结果 (1)在术后1~7 d,有7只死于左心室破裂或急性心力衰竭。其梗死面积可达(44.2±1.8)%;(2)手术组的Egr-1相对表达量明显高于正常组和假手术组(P〈0.05);(3)NF-κB P65在手术组中的表达量最高(P〈0.05)。结论在心肌梗死中有相同的刺激因表使得NF-κB和Erg-1被活化,从而使得其表达量上升为心肌梗死的诊断和预防提供条件。
Objective Objective to detecte the expression of Egr - 1 and NF - κB in myocardium ,the molecular biology methods were used .Methods (1 )The myocardial infarction rat model was obtained by operation .(2 ) Egr - 1 expression level was detected by semi - quantity PCR and immunohistochemical .(3 ) NF - κB expression level was detected by semi - quantity PCR and western blotting .Result (1 )Seven rats were died in left ventri-cle rupture or acute heart failure after operation from one day to seven days .(2 )Compared with normal group and sham operation group ,the Egr - 1 expression level in operation group was higher (P 〈 0 .0 5 ) .(3 ) NF - κB P6 5 in operation group was highest (P 〈 0 .0 5 ) .Conclusion Egr - 1 and NF - κB were actived by same activator in myocardial infarction .
