[Adrenergic control of myocardial contractile function in rats with incorporated 137Cs]. / Adrenergicheskii kontrol' sokratitel'noi funktsii miokarda krys s inkorporirovannym 137Cs.

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.
