摘要: 目的 观察缺氧-复氧对大鼠心室肌细胞的损伤及川芎嗪的保护作用 。方法 在缺氧-复氧条件下,测量对照组和不同浓度川芎嗪组对杆形心肌细胞百分比、心肌细胞内 K+/Na+浓度比及Ca2+浓度的影响。结果 缺氧-复氧对大鼠心室肌细胞有损伤作用,浓度为 4μmol·L-1的川芎嗪对缺氧-复氧损伤细胞有保护作用,它能抑制损伤细胞挛缩,提高损伤细胞生存率,抑制心肌细胞内 K+/Na+浓度比的降低 、增加细胞内 Ca2+浓度,且剂量越大,保护作用越好,即川芎嗪对缺氧-复氧损伤细胞的保护呈剂量依赖性 。结论 川芎嗪对缺氧-复氧损伤的大鼠心肌细胞具有保护作用,它能显著地对抗缺氧-复氧对心室肌细胞的损伤作用 。

Abstract: Aim To observe anoxia-reoxygenation damage to ventricular myocytes and the protective effects of tetramethylpyrazine on the damage in rats.Methods T he myocytes viability,intracellular K+/Na+,intracellular free calcium concentration were detected in different tetramethylpyrazine concentration groups and control group in the anoxia-reoxygenation damage condition.Results Anoxia-reoxygenation had done harm to the rat ventricular myocytes.Tetramethylpyrazine inhibited the myocyte contracture,increased the cell via-bility,inhibited the fall of intracellular K+/Na+,and increased intracellular free calcium concentration in the dose of 4μmol·L-1or more.And the more the dose is,the better the salutary effects are.Conclusions Tetramethylpyrazine has protective effect during anoxia-reoxygenation on the ventricular myocytes of rats.

Key words: tetramethylpyrazine, myocyte, anoxia-reoxygenation
