Figure 6. Effect of DMTU in the presence of SIN-1 or OONO− in frog cardiac fibres.

Figure 6

In A a ventricular fibre was initially superfused with the control solution. SIN-1 (100 μm), DMTU (10 mm) and OONO− (14 μm) were applied as indicated by the lines. B, summary of the effects on the active tension of SIN-1 (100 μm) and OONO− (0.6-14 μm) in the absence or presence of DMTU (10 mm). The active tension in the presence of agents was normalised to its value in the absence of agents. Bars and lines are the mean ±s.e.m. of the number of experiments indicated. Statistical differences from the control level are indicated as *P < 0.05; **P < 0.01.
