In Zollinger-Ellison patients the gastric mucosa is characterized histologically by hyperplasia both of the glands and the gastric pits. The fundic gastric mucosa is thickened with a marked increase of the specific glandular cells. In-vitro autoradiographic examination shows a significant increase in proliferation of the stomach epithelial cells in three patients with hypergastrinaemia. The mean generation time was diminished from 72 plus or minus 2 in controls to 45 plus or minus 4 hours in the Zollinger-Ellison patients owing to a reduction of the G-1 phase from 62-63 to 36-37 hours. The labelling index (3-H-index) was increased from 10.0 plus or minus 0.2 to 15.7 plus or minus 1.8%. The DNA synthesis phase, the G-2 phase, and the mitotic time were not altered compared to the controls.

() infection is a typical microbial agent that interferes with the complex mechanisms of gastric homeostasis by disrupting the balance between the host gastric microbiota and mucosa-related factors, ultimately leading to inflammatory changes, dysbiosis, and gastric cancer (GC). We searched this field on the basis of PubMed, Google Scholar, Web of Science, and Scopus databases. Most studies show that inhibits the colonization of other bacteria, resulting in a less variety of bacteria in the gastrointestinal (GI) tract.

Most gastric neoplastic lesions appear in patients with gastric premalignant conditions. Here, we present the case of a 75-year-old woman with no prior history of infection, with a big gastric adenoma resected by endoscopic submucosal dissection. Histopathological examination revealed high-grade foveolar dysplasia.
