[Adrenergic control of myocardial contractile function in rats with incorporated 137Cs]
Radiobiologiia
|January 1, 1992
Abstract:
It was shown on isolated myocardium preparations that internal gamma irradiation of rats with 137Cs (1.6 MBq/kg) decreased the contractile function of ventricles and had no essential effect on the auricle contractility. The inotropic response of myocardium to activation of alpha-adrenergic receptors decreased, and of beta-adrenergic receptors decreased.
