Koyama, Kaori, Iwao Sasaki, Hiroo Naito, Yuji Funayama, Kouhei Fukushima, Michiaki Unno, Seiki Matsuno, Hisayoshi Hayashi, and Yuichi Suzuki. Induction of epithelial Na1 channel in rat ileum after proctocolectomy. Am. J. Physiol. 276 (Gastrointest. Liver Physiol. 39): G975– G984, 1999.—In patients with colectomy, epithelial transport function in the remnant small intestine can be regulated in r...

Background Meconium ileus (MI) is one type intestinal obstruction due to inspissated meconium at the level of the terminal ileum. The purpose of this study is to present the non-ionizing ultrasound-guided approach for the treatment of meconium ileus. Materials and Methods This study was performed, prospectively, at Dr. Sheikh and Akbar children's Hospitals, Mashhad University of Medical Science...

Mucosal specimens from active Crohn's disease (ileum, n = 6; colon, n = 6), active ulcerative colitis (n = 9), normal ileum (n = 6), and normal colon (n = 6) were subjected to paired immunofluorescence staining for characterisation of macrophage subsets in situ. In the normal state, only few CD68+ macrophages (< 10%) expressing the myelomonocytic L1 antigen (calprotectin) were seen. In inflamed...

The topical effect of methotrexate (MTX) on small intestinal hexose and ion transport has been studied using an in vivo steady state jejunal perfusion technique in the rat, and short circuited rabbit terminal ileum in Ussing chambers in vitro. In rat jejunum, perfusion with MTX (1 mumol/l) caused significant reductions in water, sodium, and glucose absorption within 110 minutes of exposure. Fru...

Factors influencing transport of potassium in the human small bowel were studied using perfusion techniques in normal subjects and in patients with ileostomies. In the small intestine of normal subjects and in the ileum of ileostomy patients, potassium is distributed across the mucose in a passive transport process. Potassium transport in the jejunum was influenced to a large degree by solven...

1. The activity of peptidase enzyme(s) was measured in homogenates of mucosa taken at slaughter from sites along the length of sheep small intestine. 2. The activity of the homogenate towards six dipeptides showed a similar pattern of distribution for each substrate. Activity was lowest in the proximal duodenum, rising through the jejunum to peak in the mid-ileum and declining towards the termi...

Periportal halos are an uncommon finding on computerised tomography (CT) of the liver. Here, reported a case of periportal halos and hepatomegaly in a patient with eosinophilic gastroenteritis. A 49-year-old male presented with a six week history of right lower quadrant pain and diarrhoea. A CT of the abdomen showed hepatomegaly and multiple hypodense periportal halos around the patent portal v...

POWELL, DON W., HENRY J. BINDER, AND PETER F. CURRAN. Active electrolyte secretion stimulated by choleragen in rabbit ileum in vitro. Am. J. Physiol. 225(4): 781-787. 1973.-Purified cholera toxin added to the mucosal solution of rabbit ileum in vitro caused changes in ion fluxes and electrical properties after a 50to 60-min lag period. Potential difference and short-circuit current increased an...

Ileitis is defined as inflammation of the ileum. This condition includes ulcers, aphthous ulcers, erosions, and nodular or erythematous mucosa. Various etiologies are associated with ileitis. Crohn's disease, ulcerative colitis, medications such as nonsteroidal anti-inflammatory drugs, infectious conditions, neoplasms, infiltrative disorders, vasculitides, spondyloarthritis, endometriosis, and ...

Small bowel metastasis from primary bone leiomyosarcoma is very rare. Here we report on a 50-year-old man who presented with general weakness, weight loss (six kg in two months) and intermittent tarry stools for two months. He had undergone an above-knee amputation for left tibia leiomyosarcoma seven years previously. No local recurrence and/or distant metastasis developed during a seven-year p...
