摘　　要：目的研究早期心肌缺血大鼠模型上心肌肌钙蛋白T的脱失情况。方法应用免疫组化LSAB法显色观察。结果缺血15分钟,大鼠心肌肌钙蛋白T即有明显脱失,随缺血时间的延长,脱失面积呈扩大趋势。计算机图像分析显示缺血大鼠心肌肌钙蛋白T的脱失面积与正常大鼠心肌之间存在显著性差异。结论心肌肌钙蛋白T是诊断早期心肌缺血的较为敏感的指标之一。Objective To study the depletion of cardiac troponin T in Rats of early myocardial ischaemia. Methods Immunohistochemical method (LSAB) was used and the depletion area of CTnT in myocardial ischaemia were measured by the computer image analysis. Results There is obviously depletion of CTnT after 15 min in myocardial ischaemia of rats, the mean of CTnT depletion of myocardial ischaemic group is significant difference compared with that of the control group(P< 0.01), and the depletion area increased with the prolongagtion of ischaemic time. Conclusion The depletion of CTnT is one of sensitive signs of early myocardial ischaemia.
