Studies on Renal Pelvis

Experiments commence after a 60 to 90 min equilibrium period after which amplitude and fre- 

Concentration response curves to noradrenaline and acetylcholine are performed by non-cumulative addition to the bath at 20 min intervals. Contact time of drugs is 15 min. 

All values are expressed as mean SEM. Statistical analysis is performed by means of Student s t-test for paired or unpaired data or by analysis of variance. 

Kimoto and Constantinou (1990,1991) studied contractility of smooth muscle strips from the pacemaker regions and pelviureteric junction of renal pelvis from rabbits. 

Kondo et al. (1992) determined the effects of dobu-tamine and terbutaline on adenylate cyclase activity and cyclic AMP content in the renal pelvis of rabbits.
