Inhibition of type 1 protein phosphatase activity by activation of β-adrenoceptors in ventricular myocardium

The regulation of protein phosphatase (PP) activity by cardiac β-adrenergic receptor stimulation with isoproterenol (ISO) was studied in four groups of guinea pigs consisting of seven animals each. Group 1 received the vehicle solution only intraperitoneally; group 2, 6 μg/kg of ISO; group 3, 60 μg/...
