摘  要:目的:探讨阿霉素(ADR)对兔心脏结构及血清氨基末端脑钠尿肽前体(NT-proBNP)的影响,为慢性心衰模型的建立提供理论依据。方法:新西兰兔30只,随机分成正常对照组、模型4周组和模型8周组,每组10只(n=10)。模型4、8周组:耳缘静脉注射ADR(1.0 mg/kg,用生理盐水配制成1.0 mg/ml溶液),每周2次,共4、8周,正常对照组:注射相同体积的生理盐水。各组于末次注射7 d后,测量其左室舒张末期内径(LVEDD)、左室收缩末期内径(LVESD)、室间隔厚度(IVS)和左室后壁厚度(LVPW),并检测血清NT-proBNP水平的变化。结果:与正常对照组相比,模型4、8周两组LVDd、LVDs、IVS及LVPW均有不同程度增大(P<0.05或P<0.01),血清NT-proBNP的水平明显升高(P<0.01)。结论:ADR常规剂量长期静脉注射4、8周,可致兔心脏结构及血清NT-proBNP水平明显变化,可用于慢性心衰模型的制作。AIM:To study the effects of adriamycin (ADR) on cardiac structure and serum Nterminal brain natriuretic peptide precursor (NTproBNP) in rabbits and provide a model for chronic heart failure. METHODS: Thirty rabbits were randomly divided into three groups: 4week model group (n=10) and 8week model group (n=10, each) in which ADR was intravenously injected at the doses of 1 mg/kg twice weekly for 4 or 8 weeks, and control group (n=10) in which an equivalent volume of 09% sodium chloride was given. Seven days after the final injection in each group, the left ventricular enddiastolic dimension (LVEDD), left ventricular endsystolic dimension (LVESD), interventricular septum (IVS), left ventricular posterior wall (LVPW) and serum NTproBNP were evaluated, respectively. RESULTS: Compared with those in control group, LVDd, LVDs, IVS, LVPW and serum NTproBNP increased obviously in both model groups. CONCLUSION: Chronic administration of intravenous ADR to rabbits for 4 or 8 weeks harms the cardiac structure and raises serum NTproBNP. A model of chronic heart failure can be induced by ADR.
