FIGURE 4.
(A) A representative trace of the effect of 18β-GA (30 μM) on spontaneous pressure fluctuations in an isolated whole rat bladder, and the effect on longitudinal (distances 1, 2, and 3) and transverse (distances 4 and 5) components. Distance 4 shortens whilst distance 5 elongates, as demonstrated with respect to baseline – arrows in distance 5 demonstrate shortening and elongating events. (B) Schematic diagram depicting measured longitudinal and transverse distances. (C) Control spontaneous pressure fluctuations – arrows in pressure and distance 3 highlight pressure changes displayed by the shortening of distance 3. (D) The effect of 18β-GA (30 μM) on spontaneous pressure fluctuations – arrow in pressure and distance 3 demonstrate shortening movement of distance 3 without measurable pressure change.
