Female Wistar rats were weaned onto a diet deficient in riboflavin and compared with weight-matched and ad lib.-fed controls. The effects of riboflavin deficiency on villus morphometry and enterocyte number on the villi in the upper small intestine were studied. Riboflavin depletion was associated with increased villus length and a proportional increase in the number of cell positions along the...

AIM To investigate local corticosterone production and angiotensin-I converting enzyme (ACE) protein expression and their interaction in healthy and inflamed intestine. METHODS Acute intestinal inflammation was induced to six weeks old male Balb/c mice by administration of either 3% or 5% dextran sodium sulfate (DSS) in drinking water for 7 d (n = 12 in each group). Healthy controls (n = 12) ...

Sturgeon is one of the most important species of the Caspian Sea aquatics. Unfortunately, this species faces the threat of extinction today. This makes specific studies on any type of sturgeons more important than before. Studies like histological studies, radiology, and sonography, all require a complete understanding of the anatomy of this fish. Since pilot studies showed some misconceptions ...

to study clinical and histopathological changes occur within the first 12 hours of strangulating obstruction of the small intestine in equine, twenty five adult donkeys were used in an experimental study. strangulation obstruction of the small intestine was performed for 3, 6, 9 and 12 hours, respectively. clinical examination was done before surgery and at 3 hours intervals postoperatively. af...

intestinal tuberculosis is an uncommon presentation of tuberculosis (tb) and has clinicopathological similarities with crohn's disease. in regions where tb is endemic clinicians must aware of this condition and fully evaluate their patients when crohn's disease is diagnosed. we recommend all pathologic specimens be evaluate effectively for tb.smear,culture and pcr for mycobacterium.tuberculosis...

immunoproliferative small intestinal disease (ipsid) is the syndrome associated with mediterranean lymphoma (a rare form of non-hodgkin’s lymphoma). many of the patients diagnosed with secretory ipsid have variable level of abnormal immunoglobulins in serum or other bodily fluids, identified as truncated alpha heavy chain globulins. most cases are characterized by a loss of ability to synthesiz...

background: the pathogenesis of inflammatory bowel disease is complex and multifactorial. studies have led to the current concept that toll-like receptors represent key mediators of innate host defense in the intestine, and they are involved in maintaining mucosal as well as commensal homeostasis. we studied the possibility of simvastatin and antagonist of receptors of interleukin-1 for pharmac...

The mammalian small intestine serves principally as the site for absorption of nutrients, water, and both beneficial and potentially harmful xenobiotics. However, it has become apparent over the past 20 years, and most notably during the past 10 years, that an array of metabolic machinery is also expressed in this organ (Kaminsky and Fasco, 1992; Lin et al., 1999; Doherty and Charman, 2002; Din...

This study was carried out to investigate the effects of dietary putrescine (PUT) on broiler's response fed low crude protein (CP) diets. A total of 192 male day old chicks were fed with four dietary treatments including two levels of PUT (0 and 0.03%) and two levels of CP (normal and low) with factorial combinations. Weekly growth performance, nutrient digestibility and intestinal morphology (...
