| 中文摘要: |
| 对初次发病且发病后３６ｈ内收住冠心病监护室的４３例急性心肌梗塞（ＡＭＩ）患者，采用黄芪口服液治疗，进行了４周心功能的动态观察。研究表明，黄芪（６０ｇ／ｄ）可使ＡＭＩ患者药后射血前期／左室射血时间（ＰＥＰ／ＬＶＥＴ）比值显著下降，优于基础治疗组；同时提高ＡＭＩ患者红细胞超氧化物歧化酶（ＳＯＤ）活性，降低血浆过氧化脂质（ＬＰＯ）含量，作用均优于基础治疗组；并证明了ＰＥＰ／ＬＶＥＴ比值与ＳＯＤ活性、ＬＰＯ含量的相关性。研究表明，黄芪抗氧自由基的作用可能是其强心作用机制之一。 |
| 英文摘要: |
| Dynamic observations for 4 weeks were made on left ventricular function and oxygen free radical (OFR) in 43 patients first suffering from acute myocardial infarction and hospitalized in Coronary Care Unit with an attack less than 36 hours. The results showed that the Astragalus membranaceus (AM) could strengthen the left ventricular function and had an effect of anti-OFR.After administration of AM, the ratio of pre-ejection period/left ventricular ejection time (PEP/LVET) was decreased, the superoxide dismutase (SOD) activity of red blood cell was increased, and the lipid peroxidation (LPO) content of plasma was reduced. There was a significant difference between the AM group and the control group in the parameters above-mentioned.The study demonstrated that the PEP/LVET ratio was closely correlated with the SOD and LPO. It suggested that the anti-OFR effect of AM was one of the mechanisms of its cardiotonic action. |
