title: Effects of polydatin on attenuating ventricular remodeling in isoproterenol-induced mouse and pressure-overload rat models.
abstract: The study was designed to examine the effects of polydatin on ventricular remodeling induced by isoproterenol in mice and by abdominal aortic banding in rats. Polydatin reduced cardiac weight indexes in mice and rats, lowered the contents of cyclic AMP and angiotensin II in mice. It also decreased the size of cardiomyocyte, the levels of aldosterone, tumor necrosis factor-α, angiotensin II and endothelin-1, reduced ventricular collagen volume and decreased blood pressure in rats. The results demonstrate that polydatin has the beneficial effects on attenuating ventricular remodeling, which are associated with its inhibiting the activation of neurohormone, especially in rennin-angiotensin-aldosterone system.
