aqueous (hydrophilic) and chloroform (lipophilic) extracts of nine medicinal plants currently used in traditional medicine, in egypt, to treat some gastrointestinal tract (git) disorders were tested for their gastro-protective effect against the incidence of peptic ulcer. indomethacin-induced ulcer in a rat model was used for this testing. mentha microphylla, brassica oleracea capitata (cabbage...

The immune responses to Helicobacter pylori infection play important roles in gastroduodenal diseases. The contribution of gamma interferon (IFN-gamma) to the immune responses, especially to the induction of gastric inflammation and to protection from H. pylori infection, was investigated with IFN-gamma gene knockout (IFN-gamma-/-) mice. We first examined the colonizing abilities of eight H. py...

Stress reduces gastric blood flow and produces acute gastric mucosal lesions. We studied the role of angiotensin II in gastric blood flow and gastric ulceration during stress. Spontaneously hypertensive rats were pretreated for 14 days with the AT1 receptor antagonist candesartan before cold-restraint stress. AT1 receptors were localized in the endothelium of arteries in the gastric mucosa and ...

Alcohol consumption is inconsistently associated with the risk of gastric cancer morbidity and mortality. The aim of this study was to systematically evaluate the association between alcohol consumption on gastric cancer risk. The PubMed, Embase, and Cochrane Library databases were searched from inception through April 2017. Prospective cohort studies evaluating the association between alcohol ...

BACKGROUND AND OBJECTIVES The best alternatives to synthetic medicines, available, for the treatment of gastric ulcer disorders, are the natural products found in plants. They are known to exhibit a variety of activities. The present study is aimed at the screening of Psidium (P.) guajava Linn for its gastro protective effect. MATERIAL AND METHODS The methanol extracts of the leaves of P. gua...

The present study aimed to evaluate the protective effect of gallic acid on gastric mucosal lesions caused by ischemia-reperfusion (I/R) injury in rat. Forty male rats were randomly divided into sham, control (I/R injury) and three gallic acid-pretreated groups. To induce I/R lesions, the celiac artery was clamped for 30 min and then the clamp was removed to allow reperfusion for 6 hr. Pretreat...

Despite the fact that mucus and bicarbonate are important macroscopic components of the gastric mucosal barrier, severe acidic and peptic conditions surely exist at the apical membrane of gastric glandular cells, and these membranes must have highly specialized adaptations to oppose external insults. Parietal cells abundantly express the heterodimeric, acid-pumping H-K-ATPase in their apical me...

Two groups A and B each comprising 12 healthy young male subjects were used in a double blind, placebo controlled trial to assess the effects of 1.0 g sucralfate qid on prostaglandin (PG) generation and mucosal integrity in the intact and aspirin-treated stomach. Mucosal formation and luminal release of PGE2, 6-keto-PGE1 alpha and thromboxane B2, gastric microbleeding and DNA loss (integrity in...
