Gastric continuous with the glands are tubular, connective tissue strands simple or branched lying in between the glands, lying parallel to pyloric glands.
The cellular outline of pyloric glands is completely lost toward the luminal side.
Between days 0 and 14 the specific activity was lower in the mucosa of the fundic gland region than in the cardiac and pyloric gland regions, and was similar in all regions thereafter except for d28 in the cardiac gland region (Table 4).
There was a little difference in different gland region, in fundic gland region mucosa which was highest, and in pyloric gland region was lowest;and in contents which was lowest because of milk and grass diluted (0.
They were oval or irregular in shape, open to the lumen in the pyloric gland (Figure 14).
The CCK-IR cells were detected in the pyloric glands of M.
Pyloric gland adenoma (PGA), one of the gastric-type adenoma subtypes, is a recently noted entity with distinct attributes.
Interestingly, carcinomatous transformation is found to be associated with partial loss of expression of MUC6 (marker of pyloric gland mucin; Novocastra Laboratories, Newcastle, United Kingdom), while increased expression of MUC5AC (a marker of foveolar mucin; Novocastra Laboratories) is observed (Figure 1, B, inset), which, based on the association of MUC5AC expression with high-grade morphology, may be beneficial for discrimination of high-grade morphology.
Intraductal tubular adenoma of the pancreas, pyloric gland type: a clinicopathologic and immunohistochemical study of 6 cases.
C, Intraductal tubular adenoma of pancreas showing predominantly tubular configuration with pyloric gland feature and low-grade atypia.
Pyloric gland adenoma of the stomach occurs more commonly in older female patients.
4) Extragastric PGAs have also been associated with pyloric gland metaplasia in the setting of chronic mucosal injury.
3,9) Adenomas can also be classified by their cytoarchitectural resemblance to the different parts of the gastrointestinal tract as pyloric gland adenoma, intestinal-type adenoma, and biliary-type adenoma.
Pyloric gland metaplasia with perineural invasion of the gallbladder: a lesion that can be confused with adenocarcinoma.
MUC6 is expressed in the cytoplasm of antral pyloric glands
but also in mucous neck cells and chief cells of the gastric body.
