청둥오리 Fabricius 낭에 대한 조직학적 및 면역조직화학적 연구 = Histological and immunohistochemical studies on the endocrine cells in the bursa of Fabricius of duck, Anas platyrhynchos platyrhyncos Linne

다국어 초록 (Multilingual Abstract)

The histological profiles and endocrine cells in the bursa of Fabricius of the duck (Anas platyrhynchos platyrhyncos, Linne) were studied at 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. Histologically epithelium of bursa Fabricius were pseudostratified columnar and simple columnar epithelium. Numerous lymphatic follicles and well developed plica were observed in this study. The sections were reacted immunohistochemically using antisera specific to bovine chromogranin(BCG), serotonin and somatostatin antisera using immunohistochemical methods. A few number of BCG-immunoreactive cells were detected from 23 days of incubation to 5 weeks after hatching and serotonin-immunoreactive cells were also observed from 23 days of incubation to 3 weeks after hatching. No somatostatin-immunoreactive cells were detected in this study.
