Figure 8. Pooled data of force (A) and [Ca2+]i transients (B) at different concentrations of diethylamine/NO (DEA/NO), a NO donor.

Figure 8

Low doses of DEA/NO (up to 120 μm) increased force and [Ca2+]i transients. In contrast to AS, force decreased at higher concentrations of DEA/NO while [Ca2+]i transients remained unchanged. Temperature, 22°C; sarcomere length, 2.2–2.3 μm; n = 4.
