【摘要】 目的 :探讨复方中药丹参滴丸对缺氧 /复氧心肌细胞的保护作用。方法 :培养的乳鼠心肌细胞 ,用钙探针Fluo - 3/AM染色 ,利用激光扫描共聚焦显微镜观察心肌细胞缺氧 /复氧及在复方丹参滴丸保护作用下心肌细胞内钙离子荧光强度变化。结果 :缺氧加丹参保护组 ,细胞内钙离子荧光强度 (12 17 78± 312 0 7)明显低于单纯缺氧组 (15 0 9 43± 5 0 8 5 8) ;缺氧复氧加丹参组 ,细胞内钙离子荧光强度为 (15 6 7 91± 5 77 6 1) ,亦较缺氧再给氧组 (16 17 6± 477 5 3)低。结论 :复方丹参滴丸对缺氧心肌细胞有明显保护作用。更多还原

【Abstract】 AIM: To examine the effect of compound salvae-dropping-pill (CSDP) on intracellular free calcium in cultured rat myocardial cells subjected to hypoxia and reoxygenation.METHODS: The Fluo- 3/AM was applied to probe intracellular calcium concentration and the fluorescent intensity was detected using laser confocal microscopy technique.RESULTS: Fluorescent intensity in hypoxia plus CSDP group was significantly lower (1 217 78±312 07) than that of hypoxia group (1 509±508 48), and the Fluorescent intensity of hypoxia/reoxygenation plus CSDP group was also markedly lower (1 567.91±577 61) than that of hypoxia/reoxygenation group (1 617.60±477.53).CONCLUSION: The cultured rat myocardial cells could be effectively protected by administration of CSDP in case of hypoxia and reoxygenation through decreasing the intracellular calcium concentration.
