Isolated perfused rat heart model was used to observe the protective effects of berbamine on myocardial ischemia/reperfusion injury. The hearts were remarkably injured by 40 min global ischemia followed by 20 min reperfusion. Berbamine could significantly improve heart function, prevent ventricular

Pretreatment of berbamine protects the heart from ischemia/reperfusion (I/R) injury. However it is unknown whether it has cardioprotection when given at the onset of reperfusion (postconditioning (PoC)), a protocol with more clinical impact. Autophagy is upregulated in I/R myocardium and exacerbates

BACKGROUND Berbamine, a natural compound from Barberry, was reported to protect myocardium from ischemia/reperfusion (I/R) injury, but the underlying mechanisms are largely unknown. RESULTS Berbamine pretreatment from 10 to 100nmol/L concentration-dependently improved post-ischemic myocardial

Berbamine (molecular formular C37H40N2O6) is a bi-benzle-isoquinolyl alkaloid extracted from Berberis poiretil Schneid (genus of Berberis, family of Beridaceae), a kind of Chinese plants. In aspect of cardiovascular pharmacology, berbamine shows actions of anti-arrhythmia, anti-myocardial ischemia,

The isolated working rabbit hearts perfused with Tyrode's buffer solution persisted working in good condition at least up to 70 min. Berbamine (Ber) 3 mumol.L-1 significantly changed the hemodynamic parameters and reduced cardiac functions. The effects of Ber appeared in a dose-dependent manner.
