| Abstract |
|
The distributions and relative frequencies of bovine chromogranin(BCG)-, serotonin-, and bovine pancreatic polypeptide(BPP)-immunoreactive cells in the pancreas of the duck(Anas plaryrhynchos plaryrhyncos, Linne) were studied immunohistochemically on 23 days of incubation, at hatching, 1 week, 2 weeks, 3 weeks, 5 weeks, 6 weeks, 7 weeks, 9 weeks, 10 weeks, and 32 weeks after hatching. In the exocrine portions, the relative frequencies of BCG- and serotonin-immunoreactive cells tend to decrease according to ages. BPP-immunoreactive cells first appeared 1 week after hatching, and thereafter decreased. These cells were mainly observed in the exocrine pancreas and marginal region of the pancreatic islets. In the endocrine portions, BCG-, serotonin- and BPP-immunoreacteve cells disappeared 2 weeks, 9 weeks and 5 weeks after hatching, respectively. |
