Basal HCO(3)(-) secretion across the duodenum has been shown in several species to principally involve the activity of apical membrane Cl(-)/HCO(3)(-) exchanger(s). To investigate the identity of relevant anion exchanger(s), experiments were performed using wild-type (WT) mice and mice with gene-targeted deletion of the following Cl(-)/HCO(3)(-) exchangers localized to the apical membrane of mu...

A 65-year-old woman presented with abdominal pain, weight loss, fatigue, and microcytic anemia. Esophagogastroduodenoscopy, until the second part of duodenum, was normal. Ultrasound and computed tomography demonstrated a solid mass in the distal duodenum. A repeat endoscopy confirmed an ulcerative, intraluminar mass in the third and fourth part of the duodenum. Segmental resection of the third ...

Tubulo-villous tumours of the duodenum are rare tumours which account for less than 1% of duodenal neoplasms, 88% of which are located in the second part of duodenum. The remaining 12% are equally distributed in first and third part of the duodenum [1, 2] . A high rate of malignant transformation complicates management with surgical treatment options ranging from wide local excision to radical ...

1. Two groups of four 18-month-old ewes fitted with a rumen cannula and re-entrant cannulas in the proximal duodenum were fed on one of two diets based on varying proportions of dried-grass meal, ground straw and barley. 2. The apparent availability, retention and amount of the mineral reaching the proximal duodenum were measured for calcium, phosphorus, magnesium, copper and zinc. Significant ...

dust colour and corrugated.in patches as if caused by bites. Duodenum of same colour. Whole length of intestines is of a somewhat similar colour with several small congested spots. In case No. 6 cancruiu oris. In case No. 7 most .oi the ai)chylostoma were found alive and adhering to duodenum and jejunum. In cases Nos. 8 aud 10 hemorrhagic spots in duodenum. In casesNos. 13 and 19 anchylostoma a...

The aim of the present study was to investigate the effect of systemic oxytocin (OT) and vasopressin (VP) on the motility of stomach and duodenum. Two plastic balloons made of condom were inserted into stomach and duodenum to monitor the change of mean pressure. Intravenous injection of OT (0.1-0.8 microg kg(-1)) or VP (0.02-0.08 IU kg(-1)) dose-dependently increased the stomach and duodenum pr...

CONTEXT Superior mesenteric artery syndrome is a life- threatening upper gastrointestinal disorder due to compression of duodenum as it poses a difficult diagnostic dilemma. Third part of duodenum is in fixed compartment bounded anteriorly by the root of mesentery and superior mesentery artery and posteriorly by the aorta and lumbar spine. On barium contrast study and abdominal computerized tom...

The aim of the present study is to determine the distribution of residual circumferential strains along the duodenum in anesthetized guinea pigs. A silicone elastomer was allowed to harden in the duodenal lumen under a pressure of 0.7 kPa. The duodenum was excised with the cast and photographed. The zero-stress state was obtained by cutting rings of duodenum radially. The geometric configuratio...

The effects of trifluoperazine and verapamil on bradykinin- and des-Arg(9)-bradykinin induced responses of isolated rat duodenum and guinea-pig ileum were investigated to elucidate post-bradykinin receptor events. Verapamil and trifluoperazine inhibited bradykinin induced relaxations and contractions and des-Arg(9)- bradykinin induced contractions in rat duodenum. Bradykinin induced contraction...

Organogel as a system was to estimate its capacity delay and slow the drug release in duodenum. The gelators, 12HSA (12-hydroxystearic acid), span 60. 40 were used; castor oil (CO) anise (AO) also represented liquid phase. To achieve goal of this work by using diclofenac sodium (DS). Organogels specifications estimating thermal attitude tabletop rheology differential scanning calorimetry (DSC)....
