Effect of cerebellar lesion and vestibular stimulation (VS) on the activity and alternation of ECL-cells along with changes in gastric volume and acid secretion was studied. The results suggest that cerebellar lesion caused increased gastric volume and acid secretion and tended to decrease ECL-cell density. On the other hand VS of nodular lesioned rats resulted in decrease of above parameter wh...

An asymptomatic 72-year-old man underwent a screening esophagogastroduodenoscopy (EGD) at our hospital. The EGD showed a sessile polypoid lesion with a smooth surface in the greater curvature of the gastric antrum, which was diagnosed as a submucosal tumor (●" Fig.1a). A second slightly elevated lesion with a shallow depression was observed in the greater curvature of the lower gastric body nea...

tion of connective tissue mast cells, but not mucosal mast cells, with release of serotonin and histamine from the cells. We have shown in rats with a single C48/80 treatment that the development of gastric mucosal lesions occurs with decreases in Se-glutathione peroxidase (Se-GSHpx) activity and vitamin E and hexosamine levels and increases in neutrophil infiltration, xanthine oxidase (XO) act...

absractgastritis cystic polyposa is a rare and peculiar polypoid lesion arising at a gastroenterostomysite, and almost always on the gastric side. it is characterized by elongationof the gastric foveolae along with hyperplasia and cystic dilatation of the gastricglands extending into the submucosal layer. esophagogastroduodenoscopy in a47-year-old woman without any history of gastric operation ...

BACKGROUND/AIMS The focal nature of gastric ulcers raises the possibility of underlying regional disturbances in gastric mucosal microcirculation. This study employed fluorescent in vivo microscopy with the aim of directly investigating the response of several areas of the gastric mucosa to 60% ethanol. METHODS Changes in macromolecular leakage of fluorescein labelled albumin, vessel diameter...

the gastric inflammatory fibroid polyp (ifp) is a rare benign tumor of unknown etiology that is localized mainly in the antrum and presents endoscopically as submucosal mass. the lesion manifests as abdominal pain, weight loss, bleeding, dyspeptic symptoms, and iron deficiency anemia. we report a case of gastric ifp presented with microcytic anaemia, dyspepsia, malena and weight loss. endoscopy...

A 55-year-old lady underwent upper gastrointestinal endoscopy due to dyspeptic symptoms. Endoscopy revealed a diminutive flat reddened lesion measuring less than 2mm which appeared as an erosion in the proximal gastric body and a second diminutive one in the distal part of the gastric body [Fig. 1a, b]. Magnification Endoscopy with and without Narrow Band Imaging demonstrated distinctly differe...

BACKGROUND - Gastric subepithelial lesion is a relatively common diagnosis after routine upper endoscopy. The diagnostic workup of an undetermined gastric subepithelial lesion should take into consideration clinical and endoscopic features. OBJECTIVE - We aimed to investigate the association between patients' characteristics, endoscopic and echographic features with the histologic diagnosis ...

Objective: This study aims to investigate the clinical significance of gastrin 17 and pepsinogen in gastric cancer and precancerous lesion screening. Methods: We used ELISA to measure the levels of gastrin 17 and pepsinogen in serum from the medical examination population, which compared to endoscopic results. Then statistical analysis was performed. Results: The classical method by testing pep...

Gastric hemangioma in the neonatal period is a very rare cause of upper gastrointestinal bleeding. We present a case of hemangioma limited to the gastric cavity in a 10-day-old infant. A huge, erythematous mass with bleeding was observed on the lesser curvature side of the upper part of the stomach. Surgical resection was ruled out because the location of the lesion was too close to the gastroe...
