摘要: 目的: 观察环维黄杨星D(CVB-D) 对实验性心律失常、心肌缺血的影响。方法: 分别以胺碘酮(15 mg·kg-1, iv)、复方丹参注射液(1.0 g·kg-1, iv)为阳性对照, 采用冠状动脉两步结扎法诱发家犬心律失常和大鼠静脉注射垂体后叶素(0.5 μg·kg-1) 造成心肌损伤, 观察CVB-D(iv) 对动物心律失常、急性心肌缺血, 以及耐缺氧的影响。结果: CVB-D 可减少犬冠脉结扎所致的室性早博和室性心动过速发生次数;抑制垂体后叶素引起的大鼠心电图ST 段和T 波抬高, 大小剂量组间呈现量效关系;使小鼠耐缺氧的存活时间延长。结论: O9CVB-D 对犬冠脉结扎所致的心律失常具有对抗作用;对大鼠心肌缺血损伤有一定的保护作用;增强小鼠的耐缺氧能力。

Abstract: AIM: To study the effects of cyclovirobuxine- D (CVB-D) on experimental arrhythmia and myocardial ischemia.METHODS: The arrhythmia models were set up in the dogs with ligating coronary artery method, and myocardial ischemia model with high-dose pituitrin (0.5 μg·kg -1, iv).Some indices were observed, including the influence of CVB-D on the arrhythmia in dogs, acute myocardial ischemia models in rats, and the effects on survival time of hypoxia in mice.Amiodarone (15 mg·kg -1, iv) and compound salvia injection (1.0 mg·kg -1, iv) were set as controls, respectively, RESULTS: CVB-D could significantly reduce the incidence of ventricular premature beats (VP) and ventricular tachycardia (VT) in dogs, antagonize the rising of STsegment and T-wave of ECG in rats, and lengthen the survival time of hypoxia in mice.CONCLUSION: CVBD (iv) can antagonize arrhythmia and myocardial ischemia in animal models.
