There are two phases of fore-stomach development during the first 200 days of pouch life in tammar wallaby. For the first 170 days, the mucosa displays an immature gastric glandular phenotype that changes to a cardia glandular phenotype, which remains for the rest of the animal's life. During this 200-day period after birth, the pouch young (PY) is dependent on maternal milk, which progressivel...

In an experimental study in rats, cimetidine, a potent gastric-acid inhibitor (50 mg/kg, .p.o.) reduced the macromolecular glycoprotein level of glandular stomach. The administration of cimetidine at a dose of 50 mg/kg, which inhibited the gastric lesions induced by hypoxia (13% O2 for 6 hours), reduced the glandular stomach level of high molecular glycoproteins in animals receiving a low oxyge...

Histological lesions associated with Eucoleus sp. infection of the non-glandular stomach were discovered in a wild, urban population of Norway rats (Rattus norvegicus) trapped over a 1-year period in Vancouver, Canada. Four distinct categories of histological lesions in the non-glandular stomach were identified in association with infection in a sample of 183 rats. The apparent prevalence of Eu...

the aim of the present study was to determination the prevalence of gastric ulcer in caspian miniature horse. the design field- laboratorial study on 23 caspian miniature horses. feed withdraw 12-16 hours before study and the owners or riders completed a form about housing, medication, age, sex, cell boold counts and the biochemical profile tests were carried out. endoscope performed through th...

VSIG1, a cell adhesion protein of the immunoglobulin superfamily, is preferentially expressed in stomach, testis, and certain gastric, esophageal and ovarian cancers. Here, we describe the expression patterns of three alternatively spliced isoforms of mouse Vsig1 during pre- and postnatal development of stomach and potential function of Vsig1 in differentiation of gastric epithelia. We show tha...

The signaling pathways that are essential for gastric organogenesis have been studied in some detail; however, those that regulate the maintenance of the gastric epithelium during adult homeostasis remain unclear. In this study, we investigated the role of Fibroblast growth factor 10 (FGF10) and its main receptor, Fibroblast growth factor receptor 2b (FGFR2b), in adult glandular stomach homeost...

Five investigators familiar with gastric ulcer disease in horses met to establish a scoring system that could be utilised in future studies. Slides of gastric lesions were viewed and discussed and a scoring system established that required the nonglandular and glandular portions of the stomach to be graded separately. Each portion of the stomach (glandular and nonglandular) received a score for...

Extraskeletal osteosarcoma is a very rare tumor in humans and animals including rats. This paper describes a case of extraskeletal osteosarcoma observed in the glandular stomach of an aged female Fischer 344 rat. Grossly, a whitish solid mass was observed at the greater curvature of the glandular stomach. Histologically, the tumor consisted of both atypical polygonal and pleomorphic spindle-sha...

rrhe marked resistance of the glandular stomach of animals to spontaneously occurring cancer is well known. A similar resistance to the experi mental production of cancer has been observed, since carcinogenic agents have been fed to mice and rats without producing cancer of the glandular stomach (6) . However, when threads saturated with methylcholanthrene were imbedded in the mucosa of the sto...

The quantitative studies on the gastric glands have been carried out by Mall (1892), using the dog's stomachs, by Toldt (1880), Zimmermann (1898), Johnson (1910), and by Scott (1925, 1929), employing the stomach of the human kind as a material. But very few investigations have reported the comparative studies on the quantitative difference of the gastric glands between each part of a stomach. E...
