ABSTRACT Introduction: Metastatic squamous cell carcinoma of proximal jejunum is rare presentation, in which the diagnosis is made only after biopsy. A rare case of metastatic squamous cell carcinoma of jejunum with unknown primary is reported here. Case Report: A 75­year­ old female was presented with recurrent episodes of nausea and vomiting. On the basis of radiological investigation, diagno...

The characteristics of glucose, glycine, L-alanine, and glycyl-L-alanine absorption from the jejunum and ileum have been compared in normal human subjects. A perfusion technique has been used, and correct positioning of the perfusion tube has been confirmed by measuring the differential jejunal and ileal handling of bicarbonate. Glucose and glycine were absorbed faster from the jejunum than fro...

AIM To evaluate motoric intestinal disturbances during inflammation with Trichinella spiralis in rats as an experimental model. METHODS We examined the changes in worm-positive (jejunum) and worm-free (ileum) intestinal segments of rats infected with T. spiralis. To investigate the relationship between structural and functional changes in smooth muscle, we measured the thickness of the muscle...

indacrinone is a loop diuretic which also has uricosuric, kaliuretic, saliuretic and natriuretic effects. since it has been reported that this drug has several actions in different organs, we decided to evaluate its mechanism of action on the rat jejunum smooth muscle. after preparation of the tissues, different concentrations of indacrinone were applied. doses of 8.2×10^-6 m, 2.7×10^-5 m, 8.2×...

Abstract Selenomethionine (SeMet) is a widely used food supplement. However, the research on effect of SeMet intestinal immune function not enough. Therefore, in this experiment, was added to diet chickens, and lipopolysaccharide (LPS) as harmful stimulation study chickens. We chose chicken jejunum object. The results showed that LPS treatment decreased expressions selenoproteins induced inflam...

The diagnosis of neuroendocrine malignant tumor in the small bowel is difficult [J Oncol 2008;2008:212067]. It is usually found intraoperatively during intestinal resection and confirmed by subsequent histological examination. We reported a case of jejunum neoplasm which was misdiagnosed as Crohn's disease by capsule endoscopy. Capsule endoscopy was stuck in the jejunum stricture and was remove...

The differences in percentage inhibition by hexafluorenium bromide [hexamethylene1,6-bis-(9-fluorenyldimethylammonium) dibromide (Mylaxa, Nessler, Mallinckrodt, Germany)] and in polyacrylamide-gel disc-electrophoretic pattern of the hydrolytic activity of acetylthiocholine iodide of different fractions of rat jejunum have been reported by Das & Sayer (1 975). Scaf (1971) in his study on the eff...

Intestinal development is modified by age and nutrition, mediated in part by insulin-like growth factors (IGF-I, IGF-II) and insulin. We have investigated whether expression of IGF-I, IGF-II and insulin receptors (IGF-IR, IGF-IIR and IR; measured by real-time RT-PCR) and binding capacity (Bmax) of IGF-IR, IGF-IIR and IR in the mucosa of the small and large intestine of neonatal calves are modif...

A 55-year-old man with atrial fibrillation and cerebral infarction presented one-month history of abdominal pain, watery diarrhea, hematochezia. Abdominal computed tomography showed wall thickening a limited area the jejunum. Although his symptoms improved as result fasting fluid therapy, pain recurred after resumption oral intake. Single-balloon endoscopy revealed multiple round ulcers in jeju...
