Extracellular Calcium-Dependent Modulation of Endothelium Relaxation in Rat Mesenteric Small Artery: The Role of Potassium Signaling

Figure 1

Concentration-dependent contractions to noradrenaline (NA) of rat mesenteric small arteries were not different in the presence of 1 mM and 2.5 mM . The contractions were also the same in solutions with 4.2 mM and with 5.9 mM . Preincubation with 10 μM TRAM34 was without significant effect on the contractile responses ((a) versus (b)). .
