1.1 Important aspects on ulcer pathogenesis World-wide, peptic Ulcer disease (PUD) is considered as a common gastrointestinal disorder. It develops as a result of altered balance between offensive and defensive factors. Offensive (aggressive) factors disrupt normal mucosal integrity and allow H+ back diffusion with a subsequent cellular injury. Helicobacter pylori (H. pylori) and nonsteroidal a...

Background and Objectives Recurrent aphthous stomatitis is an inflammatory condition present since ancient era wherein numerous treatment modalities have been tried. But complete eradication of the disease has not been possible and hence newer agents are being introduced. One such agent is a flavonoid named quercetin with proven antioxidant, anti-inflammatory, and ulcer healing properties. Me...

Introduction: The importance of H. pylori as an etiological agent in gastroduodenal disease had suggested antibiotic treatment as a main target for the elimination of infection. The successful eradication of H. pylori infection was shown to resolve the gastritis, dramatically accelerate ulcer healing, reduce ulcer recurrence and the prophylactic effect on the recurrence of ulcer bleeding. Mater...

First described by Dittrich in 1847, gastroduodenal fistulas are rare and are usually acquired as a complication of gastric ulcer disease: the ulcer penetrates into the duodenum, scarring occurs, and the ulcer tract epithelializes. Fortunately, these fistulas most often are clinically innocuous, although, in the presence of renal failure and with the continuous exposure to prednisone and NSAIDs...

A series of six novel benzimidazole-pyrazole hybrid molecules was synthesized and characterized using elemental analysis (CHN) and spectroscopic methods (1HNMR, FT-IR). All the synthesized compounds were evaluated for their in vivo anti ulcerogenic activity using Albino rats (weighing 180-220 g). The interactions between the compounds and active site residues of H+/K+ ATPase were investigated b...

BACKGROUND Helicobacter pylori is the primary cause of peptic ulcer disease and an etiologic agent in the development of gastric cancer. A high frequency of H. pylori infection has been reported from resource-poor regions. H. pylori infection is curable with regimens of multiple antimicrobial agents. However, antibiotic resistance is a leading cause of treatment failure. In Africa, there are ve...

Raphanus sativus L. ‘Radish’ locally known as Fijl, is a Brassicaceous plant of cabbage family which has been reputed for its benefic medicinal properties. The present study was undertaken to evaluate the freshly squeezed Radish juice (FRJ) for its anti-gastric ulcer activity in experimental models, besides preliminary qualitative phytochemical screening. Oral administration of FRJ in doses of ...

Effects of FRG-8701, a new histamine H2-receptor antagonist, on gastric acid secretion, necrotizing agents-induced gastric lesions and acute gastric or duodenal ulcer in rats were studied. In lumen-perfused rats, intravenous injection of FRG-8701 reduced gastric acid secretion, and its antisecretory effect was almost equipotent to that of famotidine but the duration of action was substantially ...

The association ofHelicobacter pyloriwith peptic ulcer disease and gastric cancer was first proposed by Warren and Marshall in 1983 (Warren and Marshall, 1983). In February 1994, the National Institutes of Health Consensus Development Conference concluded thatH. pylori infection is themajor cause of peptic ulcer disease, and all patients with confirmed peptic ulcer disease associatedwithH. pylo...

Background: Peptic ulcers occur in that part of the gastrointestinal tract which is exposed to gastric acid and pepsin, i.e., the stomach and duodenum. Gastric and duodenal ulcers are common pathologies that may be induced by a variety of factors such as stress, smoking and noxious agents including non-steroidal anti-inflammatory drugs. Ipomoea batatas tubers (sweet potato) contain ample amount...
