A 25-year-old African American female with no prior medical/surgical history presented with abdominal pain and fever. A computed tomography scan of the abdomen and pelvis showed jejunal wall thickening with an air-fluid-filled mass in the adjacent mesentery. At laparotomy, a segmental jejunal resection with the abscess cavity followed by primary anastomosis was performed. Pathological evaluatio...

Taurine (2-aminoethanesulfonic acid) is widely distributed in animal tissues and has diverse pharmacological effects. However, the role of taurine in modulating smooth muscle contractility is still controversial. We propose that taurine (5-80 mM) can exert bidirectional modulation on the contractility of isolated rat jejunal segments. Different low and high contractile states were induced in is...

In 5-day-old immunocompetent Sprague-Dawley rats infected with either 10(2) or 10(5) Cryptosporidium parvum oocysts, transient infection resulted 120 days later in increased cardiovascular depressor response to jejunal distension and jejunal myeloperoxidase activity (P < 0.05). Nitazoxanide treatment normalized jejunal sensitivity (P < 0.001) but not myeloperoxidase levels (P > 0.05). Data warr...

A metastatic deposit from renal cell carcinoma into the jejunal wall is a rare phenomenon. Among the frequent modes of presentation, bleeding, obstruction and unexplained anaemia are commonly seen. In addition to the conventional contrast studies and computerized tomography (CT), Capsule endoscopy is a useful diagnostic tool. Factors responsible for resistant behaviour of jejunal wall are still...

PERFORATIONS COMPLICATING JEJUNAL DIVERTICULA: OUR EXPERIENCE (Abstract): Single jejunal diverticula are rare surgical entities. They sometimes present clinically due to complications, such as: perforation, bleeding, obstruction, etc. In this retrospective study we have included three cases of single jejunal diverticula complicated by perforation and subsequent peritonitis. All cases underwent ...

The jejunal mucosa of patients with coeliac disease contains significantly fewer Paneth cells (PCC) per crypt (p less than 0.001) and tissue lysozyme activity (JLA) P less than 0.001) when compared with a group of subjects with normal jejunal mucosa. Neither PCC nor JLA return to normal with complete clinical recovery and otherwise complete histological recovery on a gluten free diet. There is ...

L-Glutamate is a major oxidative fuel for the small intestine. However, few studies have demonstrated the effect of L-glutamate on the intestinal architecture and signaling of amino acids in the small intestine. The aim of this study was to investigate the effects of dietary L-glutamate supplementation on the intestinal architecture and expressions of jejunal mucosa amino acid receptors and tra...

The objective of our study was to determine the effect of continuous jejunal interposition on gastrointestinal hormones after distal gastrectomy, and lay a foundation for surgical management.Distal subtotal gastrectomy experimental model were established on 24 adult Beagle dogs. Digestive tract reconstruction of the dogs was randomly divided into continuous jejunal interposition group, Billroth...
