RT Journal Article SR Electronic T1 IV. THE EFFECT OF EPINEPHRINE UPON THE RATE OF CONTRACTION AND UPON THE CONDUCTION TIME OF PERISTALSIS AND ANTIPERISTALSIS IN EXCISED URETERS JF Journal of Pharmacology and Experimental Therapeutics JO J Pharmacol Exp Ther FD American Society for Pharmacology and Experimental Therapeutics SP 449 OP 456 VO 39 IS 4 A1 GRUBER, CHARLES M. YR 1930 UL http://jpet.aspetjournals.org/content/39/4/449.abstract AB 1. The rate of conduction of the contraction wave is the same whether the wave passes from kidney to bladder or vice versa. 2. Segments taken from the ureter near the kidney and some distance from it are equally sensitive to epinephrine. 3. Epinephrine increases the rate of conduction of both peristaltic and antiperistaltic waves in the ureter and to the same degree.
