The structure and ultrastructure of the villi of small intestinal mucosa was examined in 237 duodenal or jejunal biopsies taken from children with active celiac disease and during gluten-free diet. All biopsies were processed for light and scanning electron microscopy. Conventional histology showed four different morphological aspects: total and subtotal villous atrophy in patients on unrestric...

background the increase in intestinal permeability following damage to the intestinal mucosa in any surgical procedure, trauma or fasting is well- known. objectives our objective was to experimentally evaluate whether antioxidant consumption is associated with decreased intestinal damage in intestinal surgical procedures. materials and methods forty rabbits were used to compare the pathological...

The small intestine plays a role in obesity as well as in satiation. However, the effect of physical exercise on the morphology and function of the small intestine during obesity has not been reported to date. This study aimed to evaluate the effects of physical exercise on morphological aspects of the rat small intestine during hypothalamic monosodium glutamate (MSG)-induced obesity. The rats ...

Spleen, lymph node, bone marrow, and thymus cells from Friend leukemia virus (FLV)-infected mice were examined by scanning electron microscopy. Whereas splenocytes from normal, noninfected animals showed the expected morphological classes of lymphocytes, including cells with numerous villous projections and smoother cell types, spleen cells from mice infected with FLV showed a rapid alteration ...

Background: The application of nano-particles (NPs) in various industries is growing. Since their toxicity is not clearly understood, they can cause adverse effects on the environment. The aim of this study was to evaluate the histopathological effects of iron oxide nano-particles on the small intestine of common carp, Cyprinus carpio. Methods: Four experimental treatments were designed (15 ...

This study was conducted to determine the effects of low-protein diets supplemented with crystalline amino acids (AA) on performance and intestinal development in barrows (n=32) over 2 weeks after weaning at 18±1 day. Four maize-soybean meal based diets providing 0.93 g standardized ileal digestible lysine/MJ ME were prepared. The treatments were a control diet containing 23.1% CP (crude protei...

Morphological and histological examination of intestinal mucosal biopsy material obtained by peroral instrumentation has made an outstanding contribution to the study and understanding of small intestinal disease. Postmortem examination of small intestinal mucosa has been unsatisfactory and disappointing, the histological sections showing in most instances such extensive autolytic changes that ...
