BACKGROUND Helicobacter pylori infection is associated with diverse upper gastrointestinal diseases, such as peptic and duodenal ulcers as well as gastric cancer. Longstanding period of infection impose great risk of H. pylori-related gastric disease, based on the evidence that early childhood infection is responsible for ensuing atrophic gastritis and(More)
Quality of ulcer healing (QOUH) is defined as ideal ulcer healing featuring with the fine granular ulcer scar, high functional restoration and the resistance to recurrence. This study was designed to compare the rates of QOUH achievement in rat gastric ulcer model between acid suppressant treated group and gastroprotectant treated group accompanied with(More)
BACKGROUND Proton pump is an integral membrane protein that is ubiquitous ATP binding cassette (ABC) involved in many transport processes in all living organisms, among which a specialized form of pump, so called p-type proton pump, exists in the parietal cells of stomach. Though proton pump inhibitors (PPIs) are frequently prescribed to prevent(More)
To prove whether dietary intervention can prevent Helicobacter pylori-induced atrophic gastritis and gastric cancer, we developed cancer preventive kimchi (cpKimchi) through special recipe and administered to chronic H. pylori-initiated, high salt diet-promoted, gastric tumorigenesis mice model. H. pylori-infected C57BL/6 mice were administered with(More)
Mouse bone marrow-derived clonal mesenchymal stem cells (mcMSCs), which were originated from a single cell by a subfractionation culturing method, are recognized as new paradigm for stem cell therapy featured with its homogenous cell population. Next to proven therapeutic effects against pancreatitis, in the current study we demonstrated that mcMSCs showed(More)
Omega-3 polyunsaturated fatty acids (n-3 PUFAs), particularly eicosapentanoic acid (EPA) and docosahexanoic acid (DHA), has been acknowledged as essential very long-chain fatty acids contributing to either achieving optimal health or protection against diseases, and even longevity. Recent high impact studies dealing with EPA and DHA have sparked a renewed(More)
Chronic gastric inflammation developing after Helicobacter pylori (H. pylori) infection is responsible for either dyspeptic symptom relevant to gastritis/peptic ulcer or gastric tumorigenesis, in which acid suppressants, especially proton pump inhibitors (PPIs), play role in relieving dyspepsia as well as the eradication regimen. Among several mediators(More)
AIM To compare ecabet sodium and cimetidine in relieving symptoms of functional dyspepsia. METHODS We performed a multi-center, prospective, randomized, double-blinded controlled trial to compare the clinical efficacy of ecabet sodium and cimetidine in patients with functional dyspepsia. Two-hundred and seventy-two patients with dyspeptic symptoms(More)
Sonic hedgehog (SHH) signaling is essential in normal development of the gastrointestinal (GI) tract, whereas aberrantly activated SHH is implicated in GI cancers because it facilitates carcinogenesis by redirecting stem cells. Since colitis-associated cancer (CAC) is associated with inflammatory bowel diseases, in which SHH and IL-6 signaling, inflammation(More)
