This increment was caused by an enhanced biliary output of bilirubin monoconjugates. The effect was dose dependent but maximal at a secretin infusion of 0.80 CU. Somatostatin 0.2 and 0.8 microgram/h/100 g body wt caused a dose related inhibition of the hepatic effects of secretin both on bile flow and on biliary output of bilirubin conjugates. As secretin elicits the release of somatostatin, a feed-back system could be envisaged whereby the somatostatin released stops the effects of secretin.
