摘要
目的 :研究黄芪注射液 (MR)对麻醉开胸犬急性心肌梗死的保护作用。方法 :健康杂种犬用二步结扎法结扎冠状动脉前降支 ,记录结扎前后心电图变化 ,4时后取心肌做NBT染色 ,确定心肌梗死程度。结果 :黄芪注射液可降低开胸麻醉犬死亡率 ;降低急性心肌梗死后ST段抬高程度 ;减慢心率 ;对缺血区心肌坏死有保护作用。结论 :静脉注射黄芪注射液对犬急性心肌梗死有显著保护作用。
Objective:To investigate the protective effect of Intravenous Injection of Radix Astragali seu Hedysari on acute myocardiac infarction (AMI) in anesthetized dogs. Methods: Twenty health dogs were treated by ligating descending anterior of coronary with two-step method. The changes of electrocardiogram before and after ligation were recorded. After 4 hours myocardium were taken out and dyed with NBT to make sure of the extent of myocardiac infarction.Results: Intravenous Injection of Radix Astragali seu Hedysari could decrease the lethality of AMI, ameliorated ST changes on electrocardiogram induced by AMI, and reduced infarction area. Conclusions: Intravenous Injection of Radix Astragali seu Hedysari is effective in the treatment of AMI in anesthetized dogs.
