摘 要: | 应用大鼠实验性心肌梗塞模型,观察小檗碱(Berberine,Ber)对缺血心肌的保护作用。结果表明;Ber(总量12mg·kg-1,iP)能显著缩小大鼠冠脉结扎后24h的心肌梗塞范围,减少血清游高脂肪酸的增高,降低梗塞后病理性Q波的发生率,提示Ber对缺血心肌具有保护作用。P<0.01(n=10),306±87μmol·L-1(n=10),与正常血清比差异无显著性(P>0.05),NS组冠脉结扎后1h,4h血清FFA明显增高,与结扎前正常血清比差异有显著性(P<0.05)。Ber和Ver组与NS组比均能降低冠脉结扎后1h,4h血清FFA的增高(P<0.05)。结果见表2。表2Ber对大鼠冠脉结扎后1h,4h血清FFA的影响,n=10;与NS组比较,P<0.052.3对大鼠心肌梗塞后病理性Q波的影响各组大鼠结扎后4h,24h胸前导联(V4)心电图病理性Q波的出现率见表3。结果表明,Ber与Ver相似,能降低Q波的发生率(P<0.05)。表3Ber对大鼠冠脉结扎后4h,24hECGQ波发生率的影晌(n=10)Sham=伪结扎组,与NS组比较,*P<0.05,P<0.013讨论MIS是影响心功能的主要因素之一,M?

Protective effects of berberine on experimental myocardial infarction in rats |
| |
Abstract: | The protective effects of berberine(Ber)on experimental myocardial infarction induced by ligating the left coronary artery were estimated in rats.The myocardial infarction size(MIS)was determined by nitro-blue tetrazolium technique.Ber,as well as verspamil,played a remarkable role in diminishing the MIS within 24h,decreasing the rise of free-fatty-acids (FFA)in the serum within one hour and 4 h and reducing the incidence of Q wave in electrocardiography(ECG)after the ligation of the coronary artery.These results show that Ber possesses protective effects on ischemic myocardium. |
