摘要 目的探讨红花提取物对家兔肥厚心肌细胞内钙含量的影响。方法将30只家兔按随机分配原则分为假手术组、心肌肥厚组和红花组,每组10只。采用Langendorff灌流装置分离心肌细胞,应用荧光指示剂Fura-2/AM标记,SIMPLE-PCI图象成像系统分别测量三组心肌细胞的荧光比值,并以此比值来间接反映细胞内钙的含量的变化。结果心肌肥厚组(1.26±0.04)和红花组(1.02±0.02)较假手术组(0.85±0.04)荧光比值明显增大,具有统计学意义(P<0.05),而红花组较心肌肥厚组的荧光比值明显减小,差异具有统计学意义(P<0.05)。结论肥厚心肌细胞内钙([Ca2+]i)增加,形成钙超载,使心律失常的发生率显著升高。
