The effects of oxytocin upon tissue cAMP content and short-circuit current (SCC) were measured in the urinary bladder of the toad, Bufo marinus. Tissue cAMP levels doubled before any increment in SCC was observed, the two hormone responses were quantitatively related, and a threshold level for an effect of cAMP upon sodium transport was demonstrated. The period of time over which cAMP levels continued to rise after the threshold level had been attained seemed invariant with hormone concentration. The rate at which cAMP levels rose increased with hormone concentration yielding hormone concentration-dependent maximal levels. The decay of cAMP levels was delayed when sodium influx was curtailed, suggesting a sodium-regulatory effect upon tissue cAMP levels.
