analysis without significantly affecting intestine weight o r length. If the source of carcasses is unknown, then an analysis of small intestine weight, either as a measure of intestine size o r to examine the effects of dietary, seasonal, sex, o r age differences, should be treated with caution. If the same information can be gained by examining intestine length, this is preferred. Nevertheles...

Background & Aim:  Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used in clinical medicine. The adverse effects they produce in the gastrointestinal tract however, often limit their utility. Oxidative stress has been shown to occur in the small intestine in response to the oral administration of indomethacin. In view of this, the effect of thyme essential oil, an agent with anti-o...

This experiment was conducted to compare the effects of prebiotic as alternative feed additive to an antibiotic growth promoter (bacitracin methylene disalicyate) on the growth performance and morphometrical parameters of the small intestine of broiler chickens. One hundred and forty four day old broiler chicks were randomly assigned to one of three dietary treatments for 6 wk and each treatmen...

The aim of this study was to determine the effects silver nanoparticles (AgNPs) on morphology and enzymatic activity butterfly splitfin (Ameca splendens). Individuals both sexes, aged about five months, were exposed AgNPs at concentrations 0 (control group), 0.01, 0.1, 1.0 mg/dm3 for 42 days. On last day experiment, fish euthanized, subjected standard histological processing (anterior intestine...

we described a case of lymphoid follicular hyperplasia that arose from the ileum of a 52-year-old woman. her colonoscopy revealed a large mass in the cecum associated with multiple polypoid lesions in the ileum. histologic examination demonstrated severe lymphocytic infiltration and lymphoid follicles with regular germinal centers, without evidence of malignancy. a right hemicolectomy was perfo...

1. To study further the influence of luminal nutrition on small bowel structure and function, segments of rat jejunum and ileum were completely excluded from intestinal continuity by Thiry-Vella by-pass operations. The effect of partial deprivation of luminal nutrition was also studied in jejunal segments that had been surgically transposed to a distal position in the intestinal tract. 2. Macro...

Sublethal parasites are often assumed to have no detrimental effects on their host. However, the sublethal intestinal nematode Heligmosomoides polygyrus affects both the morphology and the physiology of its laboratory mouse (Mus musculus) host and therefore has the potential to affect host life history. The objectives of the present study were to determine (1) whether lactating and non-lactatin...
