补心活络胶囊对冠心病及其脂质过氧化作用的影响

目的]评价补心活络胶囊(由水蛭、黄芪、麦冬、三七、延胡索等中药组成)治疗冠心病的临床疗效和作用机制。方法]采用补心活络胶囊治疗冠心病175例,并和121例消心痛组对照研究,观察其对心绞痛、心电图、血清脂质过氧化物(LPO)和红细胞超氧化物歧化酶(SOD) 的影响。结果]补心活络胶囊组心绞痛总有效率为88.0％,心电图总有效率80.0％,与消心痛组比均无显著性差异;对减少心绞痛发作次数和硝酸甘油用量的作用,优于消心痛,同时明显降低患者LPO,提高SOD活性,与消心痛组比差异有显著性(P<0.05)。结论]补心活络胶囊能缓解心绞痛发作,改善心肌缺血,具有清除自由基、抗脂质过氧化损伤作用。

Effect of Buxin Huoluo Capsule for Coronary Heart Disease and Its Anti-lipid-peroxidation Mechanism

Objective] To evaluate the therapeutic effect of Buxin Huoluo Capsule (BHC) for coronary heart disease (CHD) and to explore its anti-lipid-peroxidation mechanism. Methods] One hundred and seventy-five cases of CHD were treated with BHC and 121 cases with isosorbide dinitrate (ID) . Effects of BHC on angina pectoris, electrocardiograph, superoxide dismutase (SOD) activity and lipid peroxides (LPO) level were observed. Results] In BHC group, the total effective rate in relieving angina pectoris was 88.0 % and that in improving electrocardiogram was 80.0 % , the difference being not significant as compared with ID group. As for the reduction of frequency of angina pectoris and the decrease of dosage of nitroglycerin, BHC were superior to ID. Furthermore, BHC decreased LPO level and increased SOD activity, the difference being significant (P <0.05 ). Conclusion] BHC can reduce the frequency of angina pectoris and improve myocardial ischemia, and this may be related to the clearance of free radicals and counteraction of lipid peroxidation.
