Role of cholecystokinin in the anorexia produced by duodenal delivery of peptone in rats.
    The American journal of physiology, 1999, Volume: 276, Issue:6

    We used the cholecystokinin receptor antagonist devazepide to assess the importance of CCK in mediating the anorexia produced by 2-h duodenal infusions of peptone, a protein digest, at dark onset in nonfasted rats. Peptone alone (0.14-2.24 g/h) suppressed food intake dose dependently by 18-96%, with an approximate half-maximal dose of 1 g/h. Peptone-induced reductions in caloric ingestion were comparable to the caloric loads infused. Devazepide alone (30-1,000 microgram/kg) stimulated food intake dose dependently by 30-73%, with a minimal effective dose of 100 micrograms/kg. Devazepide appeared to reverse the anorexic response to peptone (1.1 g/h) dose dependently by 29-65%, with a minimal effective dose of 30 micrograms/kg. The magnitudes of these devazepide-induced effects were similar to, and in some cases were larger than, those produced when the same doses of devazepide were administered alone. Coadministration of devazepide (1,000 micrograms/kg) and a lower peptone dose (0.8 g/h) produced similar results. These results suggest that an essential CCK mechanism plays a significant role in mediating the satiety response to duodenal delivery of protein.
