The emergence of antibiotic-resistant Helicobacter pylori is of concern in the treatment of H. pylori-associated gastroduodenal diseases. As the organism was reported to bind gastric mucin, we used porcine gastric mucin as substrate to assess the antiadhesive property of polysaccharides derived from Spirulina (PS), a commercially available microalga, against the binding of H. pylori to gastric ...

Gastric mucins are high molecular weight extracellular glycoproteins that play a major role in the protection of the gastrointestinal tract and besides that they are also involved in many disease processes. In the present study, size exclusion chromatography under non-degrading conditions was used to study the fragmentation pattern of native gastric mucins. The samples of gastric mucins of diff...

Atractylodin is one of the main constituents in the rhizomes of Atractylodes lancea Thunb., being capable of treating cancer cachexia-anorexia and age-related diseases as an agonist of growth hormone secretagogue receptor (GHSR). GHSR was herein expressed in human gastric smooth muscle cells (HGSMCs) and activated by ghrelin receptor agonist L-692,585. Like L-692,585, atractylodin also increase...

Persistent colonization of the gastric mucosa by Helicobacter pylori (Hp) elicits chronic inflammation and aberrant epithelial cell proliferation, which increases the risk of gastric cancer. Here we examine the ability of microRNAs to modulate gastric cell proliferation in response to persistent Hp infection and find that epigenetic silencing of miR-210 plays a key role in gastric disease progr...

The incidence of gastric band erosion has decreased to 1%. Gastric band erosion can manifest with various clinical symptoms, although some patients remain asymptomatic. We present a case of a mostly asymptomatic patient who was diagnosed with gastric band erosion during a routine health check-up. A 32-year-old man without any underlying diseases except for non-alcoholic fatty liver underwent la...

The sequence of events in the gastric mucosa that precede the manifestation of gastric cancer has been shown to begin decades earlier. Typically, it begins with chronic non-atrophic gastritis that progresses to chronic atrophic gastritis, which may eventually lead to intestinal metaplasia, dysplasia, and finally adenocarcinoma (Kuipers, 1999). Helicobacter pylori infection is accepted as the pr...

Sennoside A (erythro) and sennoside B (threo) are dianthrone glycosides and diastereomers. We investigated their abilities to prevent the gastric lesions associated with diseases, such as, gastritis and gastric ulcer. To elucidate their gastroprotective effects, the inhibitions of HCl•EtOH-induced gastritis and indomethacin-induced gastric ulcers were assessed in rats. It was observed that both...

The possible involvement of Toll-like receptor (TLR) genome DNA in the prolongation and relapse of inflammatory intestinal diseases and alcoholic hepatic diseases has been reported. In this study, we examined the relationship of mutations of the TLR 2, 4, 6 and 9 genomic DNA to recurrent or intractable gastritis or gastric ulcers. The subjects were 32 patients, including 6 with H. pylori (Hp)po...
