“…An average hourly secretion of about 14 ml. of pure duodenal juice was found in experiments using the same sheep under the same dietary regime as used here (Harrison & Hill, 1962). The average magnesium concentration in this juice was 1F2 + 01 (8) m-equiv/l.…”

“…A sheep with double re-entrant fistulae in the duodenum and a cannula opposite the sphincter of Oddi was used to measure the absorption of magnesium from the duodenum (Harrison & Hill, 1962). Any effect on magnesium absorption associated with the presence of bile and pancreatic juice was examined either by the addition of suitable amounts of bile and pancreatic juice to the loop solution or by repeating the experiment after initial catheterization of the common bile duct via the sphincter of Oddi, as described by Taylor (1960).…”

“…Pancreatic juice was freeze-dried, stored at -200 C and reconstituted with sterile water on the day of experiment. The bile and pancreatic juice were infused separately into the duodenum at rates similar to normal secretion rates (Taylor, 1962;Harrison, 1962) using a continuous infusion pump.…”

“…For experimental replacement of either pancreatic juice or bile, the separate secretions were collected from donor animals (see Taylor, 1960 andHarrison, 1962), and the bile was stored at -20°C until required. Pancreatic juice was freeze-dried, stored at -200 C and reconstituted with sterile water on the day of experiment.…”

SUMMARY1. The absorption of 3H-and "IC-labelled palmitic, stearic and oleic acids under control conditions and in the absence of bile and/or pancreatic juice has been studied in sheep prepared with intestinal cannulae and reentrant fistulation of the thoracic lymph duct.2. Under control conditions the percentage recoveries in thoracic duct lymph of fatty acids introduced into the duodenum were: stearic acid 59-6 + 3-2 (mean + S.E. of mean), palmitic acid 71-1 + 1-2 and oleic acid 80'4+ 1*9.3. At the peak of absorption over 90 % of the radioactivity was located in the triglyceride fraction.4. It was calculated that between 1900 and 3800 ml. lymph containing up to 20 g lipid flowed daily from the thoracic duct. The major fatty acids of lymph triglycerides were C16:0 (26 %), C18:0 (39 %) and C1,:l (19 %).5. In the absence of pancreatic juice, but in the presence of bile, the absorption of stearic, palmitic and oleic acids was 0-8, 4-1-8-5 and 26% respectively of the dose injected into the duodenum. In the absence of bile but presence of pancreatic juice corresponding values were 0 1-0 5, [1][2][3][4][5][6][7][8] and 7.7 %.6. In the absence of pancreatic juice the total lipid content of thoracic duct lymph fell from 800 to 80 mg % within 4 hr. When bile was also absent the lipid content of lymph fell further to 50 mg %.7. It is concluded that pancreatic juice functions in the lumen of the intestine probably through the production from biliary lecithin of the lysolecithin necessary for the optimum absorption of lipids.

Digestive secretions and the flow of digesta along the duodenum of the sheep

Abstract: Passage of digesta from the forestomachs of the ruminant is a more or less uninterrupted process and is reflected in the continuous nature of the secretory and mechanical behaviour of the remainder of the tract.
