Intestinal ischemia: morphological features--II.

Bollettino della Societa italiana di biologia sperimentale, 1991
Superoxide radicals produced during acute intestinal ischemia are biochemically related with the presence of hydrogen peroxyde. In this study we have investigated the distribution of peroxidase-catalase activity, histochemically determined, in the ischemic ileal wall. In the rat, complete arterial and venous occlusion produced a progressive increase in

Intestinal ischemia: morphological features--I.

Bollettino della Societa italiana di biologia sperimentale, 1991
In this research we studied the interrelationships between the progression of morphological damage and leucocyte populations in the last ileal loop after blockage of blood supply subsequent to arterial and venous occlusion. Our morphological data on the staging of the ileal wall damage agree with those reported in literature.

Effects of Hypoperfusion on Small-Intestinal Mucosal Morphology and Intestinal Barrier Function

Scandinavian Journal of Gastroenterology, 1996
Our aim was to evaluate in vitro perfusion of the rat small intestine as a method to study the pathophysiology of hypoperfusion and to minimize its adverse effects.Rat small intestine was perfused for 24 h using RPMI + albumin for the lumen and RPMI + erythrocyte concentration (Hct 20%) in the vasculature, at 22 degrees C, 15 degrees C, 10 degrees C ...

Small intestinal morphology and activity of intestinal peptidases in piglets around weaning

Journal of Animal Physiology and Animal Nutrition, 2003
SummaryThe effect of weaning on small intestinal morphology and the activities of three intestinal peptidases was investigated from 3 days prior to weaning to 9 days post‐weaning in 64 piglets. Villous height, crypt depth and mitotic counts were determined at three positions along the small intestine.

Effects of radiation damage on intestinal morphology

2001
The current flow of papers on intestinal structure, radiation science, and intestinal radiation response is reflected in the contents of this review. Multiparameter findings and changes in compartments, cells, or subcellular structure all contribute to the overall profile of the response.

Biomechanical and morphological properties in rat large intestine

Journal of Biomechanics, 2000
Intestinal stress-strain distributions are important determinants of intestinal function and are determined by the mechanical properties of the intestinal wall, the physiological loading conditions and the zero-stress state of the intestine. In this study the distribution of morphometric measures, residual circumferential strains and stress-strain ...

Myenteric plexus destruction alters morphology of rat intestine

Gastroenterology, 1993
It has been shown previously that myenteric plexus destruction by benzalkonium chloride (BAC) increased villus height, crypt depth, and muscle thickness, suggesting that these neurons influence intestinal morphology. A nonspecific trophic effect of BAC, intraluminal stasis, and inflammation resulting from the chemical treatment could also be causes for

Bacterial Translocation and Intestinal Morphological Findings in Jaundiced Rats

Digestive Diseases and Sciences, 2002
The susceptibility to sepsis in obstructive jaundice may be related to bacterial translocation (BT) from the gastrointestinal tract. We evaluated BT to visceral organs and morphological changes of the intestinal mucosa in a rat model of obstructive jaundice.

Morphological Changes on the Intestinal Mucosa in Orthotopic Neobladder

Urologia Internationalis, 2012
<b><i>Introduction:</i></b> The intestinal mucosa undergoes significant atrophic changes when it is used to reconstruct the urinary tract. We analyzed the ultrastructural changes of intestinal mucosa in the orthotopic neobladder on the basis of our clinical experience.
