A wild juvenile bean goose (Anser fabalis serrirostris) was rescued after sustaining an extensive degloving injury around the neck and chin region. Except for the degloving injury, physical and radiographic examination detected no other trauma-induced abnormality. On the day of presentation to the hospital, the patient underwent extensive debridement and suturing. A twice-daily force feeding with diluted parrot weaning food was required during the hospitalization due to severe anorexia. On day 18, the bean goose was moved to the aviary to undergo rehabilitation and feeding by itself. Management of the severe degloving injury of the cervical region with medical intervention and nutritional assistance was successful in this case, and the results of this case shows the proper management can be implemented to produce satisfactory outcomes.

The appearance of some gastrointestinal endocrine cells in the Meckel's diverticulum (MD) of the bean goose, Anser fabalis Latham was observed using specific antisera against serotonin, gastrin, cholecystokinin (CCK)-8, glucagon, secretin, somatostatin and human pancreatic polypeptide (HPP) with the peroxidase antiperoxidase (PAP) method. Among these specific antisera, serotonin-, gastrin-, CCK-8-, somatostatin- and HPP-immunoreactive cells were demonstrated in this study. Serotonin-, gastrin- and somatostatin-immunoreactive cells were detected at moderate frequency and CCK-8- and HPP-immunoreactive cells was rare and low frequencies, respectively. These immunoreactive cells were located in the superficial epithelium, intestinal crvpt and intestinal glands with spherical or spindle shaped cells having long cytoplasmic processes (open typed-cell). Mucosal layer of MD was composed of simple columnar epithelium and numerous intestinal glands. In addition, numerous lymphatic tissues were also demonstrated. In conclusion, histological profiles of MD were similar to any parts of the large intestine, especially the cecum, but the appearance, distribution and relative frequency of gastrointestinal endocrine cells were similar to those of upper parts of the small intestine. Although the exact digestive functions were unknown, the finding that the appearance, distribution and relative frequency of gastrointestinal endocrine cells in MD is similar to small intestine may be considered as distinct evidence that this organ may have some digestive functions.

The regional distribution and relative frequency of the endocrine cells in the pancreas of the bean goose were investigated by immunohistochemical methods using 6 types of the specific antisera. Spindle shaped serotonin-immunoreactive cells were detected in the exocrine portions. Spherical or spindle shaped glucagon-immunoreactive cells were observed in the exocrine and dark and mammalian type islets. In the dark type islets, numerous cells were dispersed throughout whole islets but they were located in the peripheral regions of the mammalian type islets. No glucagon-immunoreactive cells were detected in light type islets. Round or spherical shaped insulin-immunoreactive cells were observed in the exocrine and dark, light and mammalian type islets. They were observed in the exocrine regions with a few numbers. Extremely rare cells were detected in central portion of the dark type islets but moderate to numerous cells were found in the central regions of the mammalian and light type islets, respectively. Spherical or spindle shaped somatostatin-immunoreactive cells were observed in the exocrine and dark, light and mammalian type islets. A few single cells were detected in the exocrine portions. In the dark type islets, numerous cells were dispersed throughout whole islets but a few to moderate numbers of cells were located in the peripheral regions of the light and mammalian type islets. Moderate numbers of the bovine pancreatic polypeptide-immunoreactive cells were found in the exocrine portions with round, spherical or spindle shape. But no bovine Sp-1/chromogranin-immunoreactive cells were observed in this study.

The regional distributions and relative frequencies of the gastrointestinal endocrine cells in the bean goose (Anser fabalis Latham) were investigated by immunohistochemical methods using bovine Sp-1/chromogranin (CG), serotonin, gastrin, cholecystokinin (CCK)-8, somatostatin and glucagon antisera. BCG-immunoreactive cells were widespread throughout the gastrointestinal tract (GIT) with moderated frequencies except for the gizzard and proventriculus which were a few frequencies. Serotonin-immunoreactive cells were detected throughout the GIT except for the proventriculus and gizzard. These cells were observed in the pylorus with rare frequencies but numerous cells were detected in the intestinal tract. Gastrin-immunoreactive cells were restricted to the gizzard, pylorus and duodenum. These cells were most predominant in the pylorus and a few or rare in the gizzard and duodenum, respectively. CCK-8-immunoreactive cells were observed from the gizzard to ileum. The highest frequencies of endocrine cells were observed in the duodenum. These cells were increased from the gizzard to duodenum but thereafter decreased. Somatostatin-immunoreactive cells were detected in the GIT except for the large intestine. In the proventriculus and pylorus, numerous immunoreactive cells were demonstrated but a few cells were present in the other regions. Glucagon cells were observed in the gizzard, pylorus, ileum, colon and rectum with a few or moderated numbers.

한국의 서해안 지역에 위치한 새만금 지역은 만경강, 동진강 하구의 갯벌지역으로 수조류의 중요한 서식지 이다. 본 조사는 2008년 11월부터 2009년 2월까지 새만금에 도래하는 수조류 군집특성 파악을 위해 실시하였다. 월동기 동안 맹금류를 포함하여 새만금에서 관찰된 수조류는 69종, 최대개체수는 409,044개체이었다. 유사한 생태적 특징을 고려하여 분류군별로 나누어 보면 14개 분류군이 관찰되었다. 주요 우점종은 가창오리, 청둥오리, 쇠기러기, 검은머리흰죽지이었다. 쇠기러기는 조사시기에 따라 양의 상관관계를 보였다(rp=0.72, p<0.05). 주요 우점종 중 가창오리, 쇠기러기, 큰기러기, 검은머리흰죽지, 혹부리오리는 기존 연구와 비교했을 때 증가하였으며, 청둥오리, 흰뺨검둥오리, 민물도요는 큰 변화가 없었다.
