Intestinal epithelial cells (IECs) perform several physiological and metabolic functions at the barrier. IECs also play an important role in defining overall immune mucosal region. Pattern recognition receptors (PRRs) on cell surface other cellular compartments enable them to sense presence of microbes microbial products intestinal lumen. are thus crossroads mediating a bidirectional interactio...

he incidence of the diverticulum of the small bowel varies from 0.2-1.3% in autopsy studies to 2.3% when assessed on enteroclysis. it occurs mostly in patients in the 6th decade of their life. of all the small bowel diverticuli, jejunal diverticulum is the most common type. this rare entity is usually asymptomatic. however, they may cause chronic non-specific symptoms for a long period of time ...

This study was conducted to investigate the effects of thyme essential oil and enzyme supplementation on rations with two different energy (wheat or corn) protein resources (soy rapeseed meals) gut morphology digestibility broiler chickens. Three hundred eighty-four male Ross-308 chickens were used a 23 factorial arrangement treatments according completely randomized design. The morphological e...

background : this study aimed to compare three staining methods including: calcofluor white, chromotrope and quick hot gram chromotrope used in diagnosis of intestinal microsporidial spores . methods : one hundred and seventy five stool specimens were collected from patients referred to laboratory of intestinal protozoology at the school of public health, tehran university of medical sciences d...

The objective of this study was to establish the effects chestnut tannin extract or vitamin E added linseed oil-enriched diets on growth performance, meat quality, and intestinal morphology broiler chickens. A total 240 day-old Ross 308 male chicks were included in trial. 5% cold-pressed oil finisher (21–40 days), three feeding treatments with four replicates formed: without additives; + 200 IU...

The effects of synbiotic supplementation to the Moghani suckling lambs diet were investigated using 18 lambs (initial BW 5-6 kg, age 3±2 day) were divided into 3 groups and fed experimental diets for 90 days. The dietary treatments were: 1) control (lambs were fed with mother’s milk, along with their normal diets), 2) control + 3 g of synbiotic and control and 3) control + 6 g of synbiotic for ...

Broilers chickens have limited ability to utilize phytate phosphorus (PP), and the influence of nutrients on the activity and efficacy of intestinal phytase is unclear. Therefore in a 2 x 2 x 2 factorial experiment, male chicks were fed 0 or 0.21 mg/kg 25-hydroxycholecalciferol (25-OH D3), 4 or 9 g/kg Ca supplied from CaCO3 or Ca malate from 14 to 24 d of age (six pens/treatment, eight birds/pe...

There are at least two classes of Escherichia coli heat-stable enterotoxins, STa and STb. Unlike STa, which is active in suckling mice and piglets, STb is inactive in suckling mice but active in piglets and older, weaned pigs. This study examined the activity of STb in several animals and its effect on intestinal histology and cyclic GMP levels in intestinal mucosal cells. STb did not cause flu...

this research was conducted to evaluate the effects of adding five levels of ferula assa foetida powder (0, 0.25, 0.50, 0.75 and 1 percent of diet) on performance, humoral and cellular immune status and cecal microbial population. a total of 200 one-day-old mixed sex ross 308 broiler chicks were randomly assigned to 5 experimental groups with each four replicates and 10 birds in each replicate,...
