title: Effects of [1-desamino-8-D-arginine]vasopressin and papaverine on rabbit renal pelvis.
abstract: The effects of [1-desamino-8-D-arginine]vasopressin (DDAVP) (V2 receptor agonist) and papaverine on four continuous circular smooth muscle strips in rabbit renal pelvis were studied by an isometric tension recording methods. DDAVP suppressed spontaneous contractions in a dose-dependent and region-dependent way. Papaverine suppressed these contractions in a dose-dependent way simultaneously in all four portions. These results suggest that there may be distribution differences of V2 receptors in the renal pelvis. Together with its anti-diuretic action, DDAVP may merit consideration for the treatment of renal colic.
