Small-intestinal morphology in infectious hepatitis.

JAMA, 1969
We have examined small-bowel biopsy specimens in 18 patients with acute infectious hepatitis. Contrary to previous reports, we found no significant distortion of mucosal morphology and nothing to distinguish these biopsy specimens from a group of specimens from control patients. We consider the most likely reason for the difference between this and the

Gut Permeability, Intestinal Morphology, and Nutritional Depletion

Nutrition, 1998
Nutritional depletion increases the risk for postoperative complications. The intestinal barrier may be important in the underlying pathophysiologic mechanism. In this study, 26 patients were evaluated to determine whether nutritional depletion was related to gut integrity and intestinal morphology.

Morphological Adaptations of Intestinal Helminths

The Journal of Parasitology, 1991
Nematodes, trematodes, cestodes, and acanthocephalans each have become adapted in different ways to the microenvironment of the vertebrate intestine. Life in this specialized habitat affords parasites a reliable source of nutrients, a relatively homeostatic environment, and protection from predators but, in exchange for these advantages, presents the ...

Morphologic liver changes in intestinal bypass patients

The American Journal of Surgery, 1980
Abstract Intestinal bypass caused morphologic changes in the liver in 80 to 90 percent of cases. The changes were more frequent and more extensive when shorter lengths of intestine were used. Eleven percent of patients in the series showed permanent changes in the liver suggestive of cirrhosis.

Quantitative Morphological Methods in Intestinal Research

Scandinavian Journal of Gastroenterology, 1985
Measurements of intestinal length suffer from considerable errors, because of variable degrees of contraction in the longitudinal muscles. In vitro organ bath techniques may solve these problems. Villi and microvilli amplify the internal surface area; measurements of the amplification factors should be based on stereological methods.

Chronic Intestinal Coccidiosis in Man: Intestinal Morphology and Response to Treatment

Gastroenterology, 1974
A patient is described who had intermittent diarrhea for more than 20 years, documented eosinophilia and probable malabsorption for more than 7 years, and intestinal coccidial infestation documented for 10 months by biopsy. A severe mucosal lesion of the small intestine characterized by shortened villi, hypertrophied crypts, and infiltration of the ...

Morphology of the Intestinal Mucosa

1984
The three anatomic divisions of the small intestine are the duodenum, the jejunum, and the ileum. These total about 6 m in length in the human. The intestine receives the gastric chyme, which mixes with the secretions of Brunner’s glands, the crypts of Lieberkuhn, the liver, and the pancreas.

Morphologic studies of intestinal allograft rejection

Diseases of the Colon & Rectum, 1984
The usefulness of isolated intestinal pouches of an intestinal allograft for monitoring mucosal histology during rejection episodes was studied in a canine model. Total small intestinal autotransplantation was performed in four dogs, and allotransplantation in 18 dogs. Isolated pouches from the proximal and distal ends of the allografts were brought to

Intestinal occlusion: morphological features.

Bollettino della Societa italiana di biologia sperimentale, 1991
In this research we studied the possible relationships between the level and the distribution of peroxidase-catalase activity and the degree of the morphological changes in the intestinal wall during mechanical occlusion. These researches have really proved that the increase of the peroxidase-catalase enzymes correlate proportionally with the damage of

MORPHOLOGY AND HISTOCHEMISTRY OF LARGE INTESTINAL POLYPS

Acta Pathologica Japonica, 1980
In order to assess the progress of the growth of large intestinal polyps into cancer, the epithelial height and the size of the epithelial nuclei were measured. Mucin histochemistry was also carried out. The increase of the histologic grade was based on the extent of epithelial pseudostratification; epithelial height became greater and epithelial ...
