Abstract:
Intravenous injection of SPD 10 mg/kg could increase the tolerant dose of ouabain, and prevent the arrhythmias induced by acute myo-cardial ischemia in rats and that elicited by adrenaline-chloroform model in rabbits. SPD 60 mg/kg intraperitoneally could abolish the ventricular fibrillation produced by chloroform inhalation in mice. It inhibited the contractility, prolonged the functional refractory period and decreased the automaticity significantly of the isolated guinea pig papillary muscles, but no significant effect on excitability.
