In Sicily folk medicine, Opuntia ficus indica (L.) Mill. cladodes are used for the treatment of gastric ulcer. We studied the effect of administration of lyophilized cladodes on experimental ethanol-induced ulcer in rat. In this paper, we report the ultrastructural observations of gastric mucosa. The ultrastructural changes were observed by trasmission electronic microscopy (TEM) confirming the...

background: saffron is the dried stigmata of the flowers of saffron (crocus sativus l., iridaceae). saffron is well known for the treatment of gastric disorders in traditional medicine.   objectives: in the search for new potential antiulcer agents, the effects of the ethanol extract of saffron and its active constituents crocin and safranal as compared with omeprazole against gastric ulcer ind...

Agnitundirasa was tested for antigastric ulcer activity in shay rat model. Oral dose of 10 mg/kg reduced the ulceration in shay rat. With 20mg/kg dose the ulceration was completely absent. The antigastric ulcer activity of agnitundirasa (20 mg/kg) was found to be equal to the effect produced by cimetidine (20 mg/kg). The reduction in gastric acidity was more with cimetidine and the reduction in...

The present study developed an oral hepatocyte growth factor (HGF) gene therapy strategy for gastric ulcers treatment. An attenuated Salmonella typhimurium that stably expressed high HGF (named as TPH) was constructed, and the antiulcerogenic effect of TPH was evaluated in a rat model of gastric ulcers that created by acetic acid subserosal injection. From day 5 after injection, TPH (1 × 10⁹ cf...

objective: gut–brain axis (gba) is very important in creation and modulation of gastrointestinal problems. aloe vera gel has gastroprotective properties. the purpose of this study was to evaluate the effect of aqueous extract of aloe vera leaves on the gastric acid secretion and brain and intestinal water content following acetic acid gastric ulcer induction. materials and methods: gastric ulce...

Changes in redox status of gastric mucosa cells are the main pathogenic factor of gastric erosion and gastric ulcer development. Pro-oxidants can affect cell transcription activity via changes in redox-sensitive transcription factors. Egr-1 and Sp-1 may regulate the transcription of genes that are associated with the pathogenesis of gastric ulcer (growthfactors, cell cycle regulators, etc.). Th...

Cathelicidin, a cationic host defense peptide, has been shown to promote cutaneous wound repair and reaches high levels in the gastric mucosa during infection and inflammation. Therefore, we investigated whether this peptide contributes to gastric ulcer healing in rats. Ulcer induction increased the expression of rat cathelicidin rCRAMP in the gastric mucosa. Further increase in expression of r...

abstract       background and objective: baba2 and hpa genes are involved in adherence of helicobacter pylori (h.pylori) to gastric mucosal tissue. this study aimed to investigate the frequency of these genes in isolates of h. pylori from gastric biopsies and their relationship with gastritis, peptic ulcer and gastric cancer.       methods: gastric biopsy samples were obtained from patients wit...

Background: Basic fibroblast growth factor (bFGF) is a glycoprotein with stimulating ability of angiogenesis. In addition, bFGF plays an important role in wound healing process in some tissues for example gastrointestinal tract, but its ability for discrimination of various stages of wound severity in these diseases was not reported. Therefore, we aimed to determine the bFGF levels in gastric u...

Background: Chronic inflammation and dys-regulation of the immune system mechanisms are now well established as primary triggers of gastric cancer and peptic ulcer disease. Galectin-9 (Gal-9) is a member of the galectin family and known as an inducer of cell aggregation, adhesion and apoptosis. Gal-9 interaction with its main ligand T-cell immunoglobulin and mucin domain protein-3 (Tim-3) leads...
