Objectives: We investigated the ability of a novel low-molecular-weight free-radical scavenger, bis(1-hydroxy-2,2,6,6-tetramethyl-4-piperidinyl)-decandioate (IAC), to protect the gastric mucosa from indometacin-induced ulceration.
Methods: The pharmacological effects of IAC, administered orally or by intraperitoneal injection, on the gastric mucosa were assessed in a rat model of gastric ulceration induced by indometacin. The effect of IAC on the level of prostaglandin PGE2 in the gastric mucosa was also investigated.
Results: IAC, which has no ulcerative activity per se, had a preventive and protective activity against indometacin-induced gastric ulceration. This effect could be only partially attributed to a modulatory effect of IAC on PGE2 levels; it is more likely to be due to the antioxidant activity of the compound.
Conclusions: Taking into account the properties of IAC and the mechanisms underlying gastric inflammation elicited by non-steroidal anti-inflammatory drugs, IAC may represent a novel anti-ulcer agent.

To investigate the clinicopathological features, diagnosis, genetic alterations, and biological behaviors of hamartomatous inverted hyperplastic polyp (HIHP) in the gastrointestinal tract. The clinical, sonographic, endoscopic and pathologic data of 10 HIHP cases diagnosed at the First Affiliated Hospital of Air Force Medical University, Xi'an, China from January 2013 to March 2024 were collected. Their clinicopathological features and histological morphology were analyzed.

The integrity of esophageal epithelial cells in patients with gastroesophageal reflux disease (GERD) or GERD-like symptoms is the first mechanism of protection to decrease the sensitivity to gastric reflux and heartburn symptoms. We investigated the protective effects of Poliprotect (PPRO), a CE-marked medical device, on esophageal epithelial integrity using in vitro and ex vivo models. In vitro, the protective effects of PPRO were tested on Caco-2 cells.

: Acute gastric injury is a prevalent gastrointestinal disorder characterized by inflammation and damage to the stomach lining. In this study, we investigated the therapeutic potential effects of broccoli stem extract (BSE) against acute gastritis in a rat model. : The antioxidant properties of BSE were evaluated through DPPH and ABTS radical scavenging activity assays and total polyphenol content analysis.
