| Abstract |
|
The relative frequency and distribution of bovine chromogranin(BCG)-, serotonin-, somatostatin(SOM)- and S-100 protein-immunoreactive cells in the intestinal tract of the duck (Anas platyrhynchos platyrhyncos, Linne) with ages were studied using immunohistochemical methods. BCG-immunoreactive cells were detected in duodenum on 23 days of incubation. Thereafter these cells were occurred throughout the intestine. SOM-immunoreactive cells were detected in the small intestine from hatching to 9 weeks. Thereafter they were also observed in colon. Serotonin-immunoreactive cells were detected throughout the intestinal tracts after hatching. These immunoreactive cells were increased with ages except that BCG-immunoreactive cells were decreased with ages from 6 weeks after hatching. BCG- and serotonin-immunoreactive cells were most frequently detected in colon regions and SOM-immunoreactive cells in duodenum regions, but no S-100 protein-immunoreactive cells were detected in this study. |
