similar results were obtained with aminophylline ( 0.3-30.0 mg/kg , i.v . ) and isoproterenol ( 0.003-0.3 microgram/kg , i.v . ) , but their effects on the measured cardiac parameters were much more potent and long-lasting than those of fkk , when compared in doses producing a bronchodilation in similar magnitude .
