In equids, phenylbutazone at high doses induces gastric disease, primarily in the glandular portion of the stomach. However, the mechanism of nonsteroidal anti-inflammatory drug (NSAID)-induced gastric disease in horses has yet to be determined. While phenylbutazone-associated ulceration is often attributed to a decrease in basal gastric prostaglandins, this has not been demonstrated in the horse. Twelve horses were randomly assigned to treatment (n = 6; 4.4 mg/kg phenylbutazone PO in 20 ml molasses q 12 hr for 7 days) or placebo (n = 6; 20 ml molasses PO q 12 hr for 7 days) groups...

The complex diversity of nonpathogenic microbes that colonize the human body, known as microbiota, exert considerable effects on physiological homeostasis, and immune regulation. Helicobacter pylori (H. pylori) is a bacterium that frequently colonizes human stomach and is a major pathogenic agent for peptic ulcer diseases, gastric cancer, and mucosa-associated lymphoid tissue (MALT) lymphoma. Due to its acidic pH and peristaltic movements, the stomach has been considered a hostile environment for most microorganisms, however various commensal microorganisms are capable of colonizing the stomach to form a stomach niche...

Current clinical treatment of Helicobacter pylori infection, the main etiological factor in the development of gastritis, gastric ulcers, and gastric carcinoma, requires a combination of at least two antibiotics and one proton pump inhibitor. However, such triple therapy suffers from progressively decreased therapeutic efficacy due to the drug resistance and undesired killing of the commensal bacteria due to poor selectivity. Here, we report the development of antimicrobial polypeptide-based monotherapy, which can specifically kill H...

Gastric ulcer is one of the major gastrointestinal disorders affecting people worldwide. Despite medical advances, management of gastric ulcer and its complications remains a challenge facing medicine nowadays. In addition, currently available medicines exhibit limited efficacy and several side effects. In the current study, the potential protective effects of chrysin -naturally occurring flavonoid- were tested against indomethacin-induced gastric ulcer model in rats. It was found that chrysin in both doses; 50 and 100mg/kg were effective in promoting mucus secretion and preventing the rise in ulcer and lesion indices, acid production and histologic changes induced by indomethacin...

Treatment of chronic mesenteric ischemia has evolved over the last two decades. Endovascular therapy is now the treatment of choice for patients with lesions amenable to such an approach. Open revascularization remains the standard of care but is frequently being reserved for lesions containing intraluminal thrombus or severe calcification. In most cases, celiac axis (CA) stenting is not needed since revascularization of the superior mesenteric artery (SMA) alone results in symptomatic resolution. This report describes a case of a patient with chronic mesenteric ischemia and diffuse gastric ulcers found to have a common origin of the SMA and CA that was treated endovascularly using a bifurcated stent technique...

Indomethacin is a nonsteroid anti-inflammatory drug (NSAID) that is used to alleviate pain and inflammation in clinical medicine. Previous studies indicated that NSAIDs can cause gastrointestinal mucosal complications, and it is associated with mucosal lipid peroxidation and oxidative damage. Based on the evidences, decreasing oxidative stress may be an ideal therapeutic strategy for preventing gastrointestinal ulcer. Apple (Rosaceae Malus sp.) is one of the most commonly consumed fruits worldwide. The abundant polyphenolic constituents have received increasing attention for decades...
