“…4). Same findings regarding the wall structure were found in Red-Capped Cardinal (Paroaria gularis gularis) (Catroxo et al, 1997), yellow-necked mouse (Apodemus flavicollis) and in guinea fowl (Numida meleagris) (Selvan et al, 2008).…”

“…Sci., 9 (6): 280-292, 2015 mentioned that the glands were oval and lined by tall columnar epithelium. The glands consists numerous secretory tubules which were lined by cuboidal cells and each tubule continued by one duct opened into the main collecting duct which subsequently opened into luminal surface of the organ as observed similarly by Catroxo et al (1997) in Red-Capped Cardinal (Paroaria gularis) and Batah et al (2012) in Coot bird (Fulica atra) whom mentioned this glands located in submucosal layer. Tunica muscularis constructed of two layers, inner thin longitudinal and an outer thick circular layers.…”

“…Generally, the mucosa was made of three constituents, that were epithelium, lamina propria and muscularis mucosa. Catroxo et al (1997) established that the mucous membrane of the proventriculus in the red-capped cardinal consists of mucosal folds in its luminal surface, which covered by epithelium of simple prismatic cells. Its propria was structured by the connective tissue with blood vessels, infiltrated with lymphocytes.…”

The study aimed to find out the histomorphological and histochemical structures of the walls of the stomach parts in mallard. To conduct this investigation, twelve healthy birds were collected from local suppliers at Baghdad province. Later on, birds were subdivided into three equal subdivisions, each of four for gross, histological and histochemical approaches. All birds were anesthetized and their abdomens were dissected, then their stomach were identified and photographed in situ. Organs were grossly described and specimens were immersed either in 10% neutral buffered formalin or in Bouin's solution for histological fixation and then processed for histological and histochemical staining techniques, which were comprised Hematoxylin-eosin, Masson Trichrome, Periodic Acid Schiff (PAS) and PAS-Alcian Blue (AB) (pH 2.5). The gross findings showed that the stomach was consisted of two distinguishable chambers, that were proventriculus and ventriculus. The proventriculus was tubular-shaped organ. The ventriculus appeared fusiform in shape and covered by thin fatty tissue. There was well demarcation between proventriculus and ventriculus. Histologically, the proventriculus mucosa lining was simple columnar epithelium. The submucosal consists of numerous and voluminous deep submucosal glands. The covering of the ventriculus was simple cuboidal. Presence of thick cuticle layer with well-developed muscular stomach. Muscularis mucosa appeared characteristically thick layer of smooth muscle bundles arranged as, inner circular and outer longitudinal layers. The tunica muscularis appeared, as a very thick structure of smooth muscles fibers. Three layers of muscles were distinguished that were thin inner, outer longitudinal and very thick intermediate circular layers.

“…A mesma descrição foi revelada no presente estudo, mas o espessamento da camada muscular é característico na região pilórica do estômago do T. tetradactyla. Contrariando tais autores, Catroxo et al (1997) encontraram no ventrículo do cardeal vermelho (Paroaria gularis) um epitélio prismático simples, e Illanes et al (2006), no ventrículo de avestruz, um revestimento epitelial cilíndrico simples. O tamanduá-mirim, assim como as aves, não possui dentes, por isso seu alimento precisa ser quebrado no estômago para que seja digerido.…”

 RESUMODiante do escasso conhecimento morfofisiológico do trato digestório do Tamandua tetradactyla, este trabalho pretendeu esclarecer a morfologia do estômago dessa espécie. Utilizaram-se seis espécimes, sendo três machos e três fêmeas jovens, provenientes da área de Mina Bauxita Paragominas -PA, doados, após morte por atropelamento, ao Laboratório de Pesquisa Morfológica Animal (LaPMA). Os animais foram fixados com solução aquosa de formaldeído (10%), seguido de dissecação, avaliação da topografia do estômago, com posterior descrição, mensuração e coleta de material para microscopia. As análises topográfica e macroscópica revelaram que o estômago, unicavitário, com presença de pequena e grande curvaturas, estava localizado no antímero esquerdo da cavidade abdominal, ligado cranialmente ao esôfago e caudalmente ao duodeno, e apresentou um aumento de superfície na região pilórica (toro pilórico). Histologicamente, era constituído por epitélio colunar simples (região glandular), epitélio estratificado pavimentoso (região aglandular), lâmina própria, muscular da mucosa, submucosa, muscular circular interna, muscular longitudinal externa e serosa. A região do piloro apresentou um grande espessamento da camada muscular da mucosa, e foram observadas nesta região fossetas gástricas profundas. O estômago de T. tetradactyla revelou características morfológicas macroscópicas e histológicas semelhantes às espécies domésticas e selvagens.Palavras-chave: Tamandua tetradactyla, morfologia, região gástrica ABSTRACT Given the limited morphophysiological knowledge about the digestive tract of Tamandua tetradactyla, this study aimed to clarify the morphology of the stomach of this species.

“…Bezuidenhout and Van Aswegen [2] and Illanes et al [3] in their research about African ostrich stomach mucosa have found out that the structure of superficial glands varies from simple to branched tubular glands. On the other hand, in most species of birds, including broilers, the structure of the superficial proventricular glands is simple tubular without branching [4][5][6][7]. Moreover, comparing the intestinal crypts of the two birds species, according to the literature, the deepest D DAVID PUBLISHING intestinal crypts in the ostrich chicks between day 1 and day 45 of life are found in the ileum [8]; while in the chicks of Gallus gallus domesticus, the deepest crypts over the first day of life are observable in the duodenum [9].…”

Abstract:The hexoses glucose, galactose and fructose serve as important dietary energy sources in animals and glucose plays a central role in energy homeostasis within eucaryotic cells. As relatively little is known about patterns of hexose transporters expression in birds gastrointestinal tract, the aim of the study was to examine glucose transporters 2 (GLUT-2) and glucose transporters 5 (GLUT-5) expression in stomach and duodenal epithelium of two different species-broilers (Gallus gallus domesticus) and ostriches (Struthio camelus var. domesticus) chicken. Materials from the two parts of gastrointestinal tract were collected from six 7-day-old female broilers and six 7-day-old female ostriches. Specimens were fixed with 10% formalin, embedded into paraffin, cut into 7 μm thick slices, followed by immunohistochemical staining with polyclonal primary antibodies rabbit anti-GLUT-2 and rabbit anti-GLUT-5; the staining was carried out according to the manufacturers guidelines (IHC kit, Abcam, UK). The investigation showed that the staining for both antibodies was more intensive in the epithelial cells of stomach and duodenum of the 7-day-old broilers. In duodenal epithelium, goblet cells and brush border membranes were stained in both species, however the signal was stronger for GLUT-5 than GLUT-2. Staining for GLUT-2 and GLUT-5 occurred in different parts of gastrointestinal tract of 7-day-old ostriches, but was weaker compared to 7-day-old broilers, which showed that the gastrointestinal tract of 7-day-old female broilers was more developed for transportation of hexoses than 7-day-old female ostriches.
