jejunal

Survival is least good for those people with isolated duodenal or jejunal disease.

To our knowledge there are no in vitro studies using jejunal mucosa.

Jejunal secretion is, however, known to occasionally occur in healthy subjects.

It compares well to jejunal aspirates in making the diagnosis of bacterial overgrowth.

However, there are a few jejunal lymph nodes suspended in its mesentery.

More recent investigations with rat jejunal brush border membrane vesicles, however, have found evidence only for passive transport.

Jejunal feeding tubes may be placed during surgery to provide a temporary route of nutrition until oral eating resumes.

Jejunal mucosal changes were more pronounced in the patients who had received 500 mg/day gliadin.

Coeliac disease is characterised by flattened jejunal mucosa which causes malabsorption.

The jejunal arteries are branches of the superior mesenteric artery which supply the jejunum.

Alimentary (rapid jejunal emptying with exaggerated insulin response)

The jejunal veins drains the jejunum and are tributaries of the superior mesenteric vein.

For clarity, some sources prefer instead using the more specific terms ileal arteries and jejunal arteries.

The morphometric parameters of the jejunal biopsy specimens before and after challenge were analysed by the discriminant function analysis.

Furthermore, restricting intraluminal sodium concentration in jejunal perfusion does not seem to limit glucose absorption.

An additional 32 biopsies from adults investigated for diarrhoea but with a normal jejunal mucosa on histology were selected as controls.

The differences between the ileal arteries and the jejunal arteries can be summarized as follows:

Symon studied net fluid and sodium transport in the jejunal segment with the most severe inflammation 10 days after inoculation.

The jejunal mucosa may show partial villous atrophy, but the changes tend to be milder than in coeliac disease.

The timing of the jejunal biopsies, antigliadin antibody test, and sugar intestinal permeability test is shown in Figure 1.

A discussion of the use of this method in the morphometric analysis of jejunal mucosa specimens is given by Penna et al.

Jejunal and ileal varices account for approximately one third of bleeding ectopic varices.

It would be difficult to distinguish osmotic effect (jejunal malabsorption) from diarrhoea generated entirely from within the colon, as implied by other workers.

Na + /H + exchange is present on the apical membranes of jejunal epithelial cells.

These unusual changes were never found in any jejunal samples and occurred only occasionally as weak signals in ileal samples from wild-type animals.
