目的:探讨不同浓度的黄芪甲苷对乌头碱诱导的斑马鱼心脏损伤的保护作用.方法:挑选受精后发育正常的48 h斑马鱼胚胎,用30 mg/L的乌头碱溶液药浴,同时给予10、25、40μg/m L的黄芪甲苷溶液,观察斑马鱼的心率、心脏形态以及静脉窦-动脉球(SV-BA)距离的变化,观察黄芪甲苷对其心脏损伤的保护作用.结果:30 mg/L的乌头碱溶液处理24 h可致斑马鱼心率加快、心包水肿、SV-BA间距延长.25、40μg/m L黄芪甲苷溶液能降低斑马鱼的心率,减轻斑马鱼心包水肿的程度.结论:黄芪甲苷对乌头碱诱导的斑马鱼心脏损伤具有一定的保护作用,且呈剂量依赖性.“,”Objective: To investigate the protective effect of astragaloside Ⅳ at different concentrations on aconitine-induced zebrafish heart injury. Methods: Zebrafish of 48 hours post fertilization were treated with 30 mg/L aconitine solution and 10, 25, and 40 μg/m L astragaloside Ⅳ solution for 24 h. We observed the heart rate, heart shape, and SV-BA of zebrafish. Results: The 30 mg/L aconitine solution can cause zebrafish heart injury such as heart rate increase, ventricular arrest, pericardial edema. The study found that 25 and 40 μg/m L astragaloside Ⅳ solution can reduce the heart rate of zebrafish and relieve the extent of pericardium edema. Conclusion: The Astragaloside Ⅳ shows a certain protective effect on aconitine-induced cardiac damage in zebrafish, which is dose-dependent.
