For many years physiological properties within the body that lead to or prevent ulceration of gastric and duodenal mucosa have been thought of as being 'aggressive' or 'defensive' in nature. Peptic ulcer has been assumed to develop when the summation of aggressive factors is greater than defensive, and a past concept has assumed that an increase in the latter or decrease in the former would lea...

Between 1957 and 1969 700 patients with duodenal ulceration were treated by selective vagotomy and simple drainage using the electrical stimulation test to achieve complete nerve section. Ten of these patients have been re-admitted to the hospital with further ulceration, one with a lesser curve gastric ulcer and nine with recurrent duodenal disease. The first patient had gastric retention and ...

duplications of gastrointestinal tract are congenital anomalies found in about 0.2% of all children. these include the rare gastric duplication. we present such a cyst in a 14 years old girl with gastric outlet obstruction. she was found to have a noncommunicating antral duplication cyst .the cyst was managed by cystectomy and marsupialization. microscopically the duplication cyst contained a m...

There is increasing evidence that blood group substances play a rôle in the causation of disease or in the protective mechanism against it. This paper records the special liability for patients of blood group O to develop stomal ulceration. Other data studied failed to confirm previous work suggesting that in gastric ulceration or neoplasm blood group A was a characteristic of an antral lesion.

Four experiments were conducted to evaluate the effect of diet and the administration of H2-antagonists in feed on gastric ulcer formation and performance of growing-finishing swine. Pigs receiving a finely ground diet (less than lmm) grew faster (.73 vs .68 kg/d, P less than .01) and had better feed utilization (3.47 vs 3.76, P less than .01) than pigs receiving a cracked corn-based diet. Inci...

Objective(s) Gastric ulceration is induced by various forms of stress like surgery, ischemia and trauma. The female sex has more resistance to stress and the gastrointestinal lesions happen fewer than male sex. The purpose of this study was to evaluate the role of estradiol and progesterone on the gastric acid and pepsin levels following traumatic brain injury (TBI) induction. Materials and M...

This study investigated the quantitative polyphenolic constituents and gastroprotective effects of aqueous leaf extracts of Spondias mombin and Ficus exasperata against indomethacin-induced gastric ulcer in rats. Ulceration was induced by a single oral administration of indomethacin (30 mg/kg body weight). Wistar rats were pretreated with esomeprazole (reference drug) at a dose of 20 mg/kg body...

Gastric microbiology of the pig has been given a great deal of attention in the past decade. Much of the work in this area has been published in human medical journals, and therefore, swine practitioners may not be aware of these recent findings. The pig has been used in the study of gastroduodenal ulcers of humans. The stomach of pigs has been successfully colonized experimentally by Helicobac...

Anti gastric ulcer activity of root, stem and leaves of Amaranthus spinosus Linn. was studied against ethanol, hydrochloric acid, indomethacin, stress and pyloric ligation induced gastric ulceration in albino rats. Omeprazole was used as standard anti gastric ulcer drug. Significant anti gastric ulcer activity was noted in root, stem and leaves of Amaranthus spinosus Linn. Root of the plant, ho...
