title: Hepatic excretion of cholecystopaques introduced into the canine jejunum.
abstract: The biliary excretion of five oral cholecystopaques was measured following their introduction into the jejunum of bile fistula dogs. The mean maximal iodine concentration in the bile ranged form a low of 2.2 +/- 0.55 mg per ml following a dose of 33 mg of iodine per kg of iopanoic acid to a high of 12.9 +/- 1.4 mg per ml after the same dose of sodium ipodate. Cumulative excretion at the end of three hours was over five times greater with sodium ipodate in comparison to ipoanoic acid. It is felt that the best explanation of this date is the ability of the more water soluble media to pass through the unstirred water layer of the intestine.
