Bioaccumulation of heavy metals including Cd, Pb, Cu and Zn in muscle, gill, liver, kidney and stomach in Acipencer persicus was studied. Fish were collected from the ‘Iranian fishery zone 1’ located between Astara and Kiyahshahr. Samples (n=25) were collected from five stations in the study area during the autumn catch season in 2001. Samples were analyzed by wet digestion with hyd...

AIM The incidence of stomach cancer in Mizoram is highest in India. We have conducted a population based matched case-control study to identify environmental and genetic risk factors in this geographical area. METHODS A total of 102 histologically confirmed stomach cancer cases and 204 matched healthy population controls were recruited. GSTM1 and GSTT1 genotypes were determined by PCR and H. ...

The Bioaccessibility Research Group of Europe (BARGE) has carried out an inter-laboratory trial of a proposed harmonised in vitro physiologically based ingestion bioaccessibility procedure for soils, called the Unified BARGE Method (UBM). The UBM includes an initial saliva phase and simulated stomach and intestine compartments. The trial involved the participation of seven laboratories (five Eu...

Ghrelin, an endogenous ligand for the GH secretagogue receptor was characterized recently from extracts of rat stomach. We describe the enteric distribution of ghrelin, ontogeny of stomach ghrelin gene expression, effects of dietary and endocrine manipulations, and vagotomy on stomach ghrelin mRNA and peptide levels and secretion in the rat. Ghrelin expression was examined by Northern blotting....

The structural characterization and function of the stomach in the omnivore Pygocentrus nattereri were described using light and scanning electron microscopy. The sac-like stomach was morphologically divided into the cardiac and pyloric regions. The histological structure of the stomach consisted of four layers of the mucosa, submucosa, muscularis, and serosa. The superficial epithelium of the ...

that the gallium activity was located near the stomach. After another glass of water was taken, the stomach was imaged again, using the upper three gallium peaks and thus excluding the Tc99m energy. This showed that the gallium activity was no longer present in the stomach (Fig. I). Gallium and Tc-99m were seen on the oscilloscope to enter the small bowel. An image taken 30 min later did not sh...

We herein report a patient who presented with follicular lymphoma. Although the stomach was initially intact, mucosal redness and multiple erosions appeared in gastric body owing to infiltration of lymphoma cells. Subsequently, slightly depressed, white area lacking structure detected lesser curvature cardia body, where cell also pathologically observed beneath stratified squamous epithelium. T...

 The endocrine cells of Salmo trutta macrostigma stomach and pyloric caeca have been investigated using immunohistochemical techniques. 8 antisera were tested and 6 of them were detected in the endocrine cells serotonin, somatostatin, substance P, galanin, CCK and neuropeptide Y. These immunoreactive cells are described for the first time in the stomach and pyloric caeaca of Salmo trutta macros...

Benign Gastric tumors are rare and generally account for less than 10% of all stomach tumors. Gastric lipoma is a rare tumor that constitutes approximately 3% of all benign tumors of the stomach and mainly is seen as a submucosal mass. Most gastric lipoma are asymptomatic and are found accidentally. Occasionally they can cause symptoms such as gastrointestinal bleeding, obstruction, abdominal p...
