Reverse transcription-polymerase chain reaction was used to detect the expression of CaL-α1CandKATP-Kir6.1 mRNA in the myocardial cell membrane of all groups of rats. RESULTS: Total flavonoids from Ganshanbian(Herba Hyperici Attenuati) can delay the appearance of myocardial ischemia reperfusion arrhythmias,shorten the duration of myocardial ischemia reperfusion arrhythmias, reduce heart rate, reduce cell membrane expression of CaL-α1C mRNA and enhance the expression of KATP-Kir6.1 mRNAin myocardial ischemia-reperfusion arrhythmic rats.CONCLUSION: Total flavonoids from Ganshanbian(Herba Hyperici Attenuati) can alleviate arrhythmias by affecting the expression of L-type calcium channels and ATP-sensitiveK+ channels.展开更多
