Effect of intravesical administration of oxo-M on evoked action potentials in the pelvic afferent nerves. A: Submaximal electrical stimulation (80 V, 0.15 ms) of the nerves on the surface of the bladder at the arrow evoked a discharge on the pelvic nerve during infusion of Krebs solution. B: 50 µM oxo-M transvesical infusion increased the evoked discharge. C: After infusion of 5 µM AMN in combination with 50 µM oxo-M the evoked discharge decreased. Evoked action potentials represent the computer average of 5 individual responses.
