Figure 11: Influence of coincubation with PUAT + L-NNA on contractile responses to ACh of PUAT-free ureters. ACh stimulated contractile magnitudes of PUAT-free ureters in the absence (control, closed bars, 𝑛 = 1 0 ) and presence (open bars, 𝑛 = 1 0 ) of a ureter + PUAT and L-NNA. Contractile magnitudes were not significantly different.
