KONDO, S., SAEKI, H., MORITA, T., TSUCHIDA, S., SHIMA, H. and TASHIMA, Y. Effects of Dobutamine on Cyclic AMP Content in Canine Upper Urinary Tract Tissue. Tohoku J. exp. Med., 1985, 146 (3), 371-372-There was no regional difference in tissue cAMP content throughout the upper urinary tract specimens obtained from dogs immobilized by pancuronium bromide (0.1mg/kg, i.v.). The cAMP content was increased in all regions examined 5min after administration of dobutamine (1mg/kg, i.v.) and pancuronium bromide. The increase was much higher in the pelvicalyceal region than in the other upper urinary tract tissue. The responsiveness of the pelvicalyceal region where pacemaker cells for ureteral peristalsis exist is considered to be higher than that in the other upper urinary tract tissue in respect to dobutamine-induced cAMP increase.
