    Journal: Regul Pept; 1987 Dec; 19(5-6):365-72. PubMed ID: 3438492.
    Abstract:
    The objective of this study was to characterize the distribution and concentration of peptide YY (PYY) in the gastrointestinal tract of the rat, dog, and monkey. In the rat, the greatest concentration of PYY was detected in the ileum and colon. The concentrations of PYY in the ileum and colon were 72 +/- 49 and 768 +/- 180 ng/g tissue, respectively. In the dog, PYY was found primarily in extracts of the mucosal layer of the ileum and colon, with smaller amounts in the distal jejunum. The concentration of PYY in the mucosal layers of the canine distal jejunum was 113 +/- 25 ng/g tissue, proximal jejunum 302 +/- 56, mid jejunum 507 +/- 151, distal ileum 691 +/- 184, and colon 1706 +/- 774 ng/g tissue. In the monkey gastrointestinal tract, PYY was detected predominantly in mucosal extracts of the jejunum, ileum, and colon. The concentration of PYY in the mucosal layer extract of the jejunum was 92 +/- 23, ileum 615 +/- 127, and colon 1013 +/- 243 ng/g tissue.
