Morphology of the Intestinal Mucosa
1984The 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.

Quantitative Morphological Methods in Intestinal Research
Scandinavian Journal of Gastroenterology, 1985Measurements 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.

MORPHOLOGY AND HISTOCHEMISTRY OF LARGE INTESTINAL POLYPS
Acta Pathologica Japonica, 1980In 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 ...

Small intestinal morphology and activity of intestinal peptidases in piglets around weaning
Journal of Animal Physiology and Animal Nutrition, 2003SummaryThe 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 Hypoperfusion on Small-Intestinal Mucosal Morphology and Intestinal Barrier Function
Scandinavian Journal of Gastroenterology, 1996Our 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 ...

Biomechanical and morphological properties in rat large intestine
Journal of Biomechanics, 2000Intestinal 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 ...

Morphologic liver changes in intestinal bypass patients
The American Journal of Surgery, 1980Abstract 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.

Effects of radiation damage on intestinal morphology
2001The 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.

Intestinal metaplasia of the gallbladder: A morphologic and immunocytochemical study
Human Pathology, 1986The morphologic spectrum of intestinal metaplasia was studied in 49 gallbladders that had been excised because of cholelithiasis. Based on the absence or presence of endocrine cells, the cases of intestinal metaplasia were arbitrarily divided into two groups.

Gut Permeability, Intestinal Morphology, and Nutritional Depletion
Nutrition, 1998Nutritional 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.
