摘要 目的:探索应用MTT法测定离体大鼠心室肌不同部位细胞活性的差异。方法:采用SD大鼠心肌不同时程缺血/再灌注模型,以MTT法分别检测心室肌不同部位的细胞活性。结果:与缺血对照组相比,随着缺血时间的延长,各组心肌细胞活性均有所下降。分别缺血15 min和60 min后,离体大鼠心室肌不同部位细胞活性无显著性差异;分别缺血30 min和45 min后离体大鼠心室肌不同部位细胞活性由大到小为:右心室>室间隔=左心室。结论:通过MTT法检测的心室肌细胞活性可得出,拟采用15-60 min缺血/再灌注模型,缺血在15 min至60min之内,则心室肌以右心室心肌细胞受损较轻,而左心室与室间隔心肌细胞受损较重。
