Article Synopsis
  • Lactoferrin is a natural immunomodulator with known anti-inflammatory effects, and this study aimed to explore its protective role against esophageal damage from acid reflux in rats.
  • The research involved male Wistar rats and assessed the impact of lactoferrin on gastric acid secretion and esophageal damage after inducing acute acid reflux.
  • Results showed that lactoferrin significantly reduced esophageal damage, improved tissue weight and scores, and lowered proinflammatory markers, indicating its potential as a protective agent against acid reflux in the esophagus.

Article Synopsis
  • Endoscopic injection sclerotherapy is commonly used for treating esophageal varices, but it can lead to complications like pleural effusions, which are not extensively studied.
  • A study involving 128 patients found that 17.7% developed small pleural effusions post-sclerotherapy, with several factors such as ascites, chest pain, and the volume of sclerosant correlating with this complication.
  • The findings indicate that the likelihood of pleural effusions increases with higher amounts of sclerosant injected, highlighting the need for cautious dosage during the procedure.

Article Synopsis
  • - Elevated nitric oxide (NO) production from inducible NO synthase (iNOS) in the esophagus is linked to increased mucosal damage in reflux esophagitis, while endothelial NO synthase (eNOS) and vascular endothelial growth factor (VEGF) levels didn't show a significant correlation.
  • - A study measured mRNA levels of iNOS, eNOS, and VEGF in biopsy samples from 25 reflux esophagitis patients, finding a direct relationship between iNOS expression and the severity of esophagitis.
  • - The findings suggest that targeting NO production could be a potential therapeutic strategy to mitigate mucosal injury in reflux esophagitis patients.

Background: Medication for the relief of heartburn should have the rapid onset of action required for on-demand use. We studied the inhibition of gastric acid secretion by lafutidine and rabeprazole, given in single doses to fasting and postprandial subjects.

Methods: A total of 22 healthy male, Helicobacter pylori-negative volunteers participated in this randomized, two-way crossover study.

Background/aims: Triple therapy consisting of lansoprazole, amoxicillin, and clarithromycin (LAC regimen) is widely used to eradicate Helicobacter pylori in Japan. However, the need for appropriate treatment after failure of initial therapy to eradicate H. pylori has been increasing.

Background: The ideal medication for the treatment of acid-related diseases, for example, hemorrhagic ulcers and stress-related gastric bleeding, should have a rapid onset of action to promote hemostasis and alleviate symptoms. The aim of our study was to investigate the inhibitory effects on gastric acid secretion after single intravenous administrations of omeprazole 20mg and famotidine 20 mg.

Methods: Ten healthy Helicobacter pylori-negative male subjects participated in this randomized, double-masked, two-way crossover study.

Background And Aims: An ideal medication for heartburn should have the rapid onset of action needed for on-demand treatment. However, assessment of the onset of action of proton pump inhibitors has been largely subjective. We compared the inhibitory effect on gastric acid secretion of a single oral dose of omeprazole with that of rabeprazole.

Background: Recent studies have shown that the number of patients with reflux esophagitis is increasing in Japan, but the prevalence and risk factors associated with reflux esophagitis in Japanese patients are not well defined.

Methods: By using all endoscopic records in the Katta General Hospital from April through to September 1999, we identified 392 patients. We examined the Los Angeles classification, peptic ulcer, gastric mucosal atrophy, hiatal hernia and other medical variable factors for their contribution to esophagitis in the patients.

Background And Aims: The natural immunomodulator, lactoferrin, is widespread among various biological fluids and is known to exert an anti-inflammatory effect. However, there has been only one study that examined the mode of action of lactoferrin in reducing intestinal damage. We investigated the therapeutic role of lactoferrin and its effect on the levels of pro-inflammatory and anti-inflammatory cytokines, by using a rat model of dextran sulfate sodium (DSS) induced-colitis.

Natural immunomodulator lactoferrin is known to exert an anti-inflammatory effect. However, there have been no studies that examine the mode of action of lactoferrin in reducing intestinal damage. We investigated the effect of lactoferrin on a trinitrobenzenesulfonic acid (TNBS)-induced colitis model in rats.
