Timed dose-response relationship of depressive action of ouabain on toad heart contraction in vitro. %K %X Timed dose-response relationship (TDRR) of depressive action of ouabain (Oua) 0.01-30 mmol.L-1 on toad heart contraction in vitro was studied by simultaneous recordings of mechanical tension and electrocardiography. It was found that the inhibition of contraction tension, the latency, the half equilibrium time of depression, and the cardioplegia time (CPT) were all concentration-dependent (P %U http://www.chinaphar.com/article/view/8828 %V 14 %N 6 %P 523-526 %@ 1745-7254
