in the present study, chicory root powder (crp) as growth promoter at 1% and 3% levels was supplemented in broilers’ diet to investigate the growth performance and histo-morphometry of jejunum. one hundred twenty, one-day-old male broilers were used in a completely randomized design (crd) with 3 treatments and 4 replicates (10 chicks per replicate). at the end of each period (0-10, 11-24 and 0-...

The gastrointestinal health of poultry can be impacted by a variety factors including their environment. As egg production moves from conventional cage housing (CC) toward cage-free (CF), it is important to understand this impact on intestinal health. This study was conducted determine if type permeability, morphology, and microbial communities in commercial hens across systems. Hens were rando...

OBJECTIVE Disturbed intestinal barrier function due to 'leaky' tight junctions may cause secondary sepsis via paracellular translocation across the gut wall. Our objective was to describe the effects of critical illness on duodenal morphology and ultrastructure. DESIGN, SETTING AND PARTICIPANTS Prospective observational study of 12 mechanically ventilated critically ill patients in an intensi...

We studied the effects of heat-killed Tsukamurella inchonensis on immune parameters and intestinal structure in mice. Mice were treated with three doses of bacteria (5 × 107, 1 × 108 and 2 × 108 CFU/mouse) consecutively for seven days. Body weight, delayed type hypersensitivity response, relative organ weight, and haemagglutination titres were studied in different groups of animals. Villus heig...

BACKGROUND Small intestinal epithelial cells (IEC) show apoptosis in physiological turnover of cells and in certain inflammatory diseases. AIMS To investigate the role of caspases in the progression of IEC apoptosis in vivo. METHODS IEC were separated along the villus-crypt axis from the jejunum of normal and Nippostrongylus brasiliensis infected rats at 4 degrees C. Caspases were examined ...

The brush-border membrane (BBM) of enterocytes is responsible for the digestion and absorption of nutrients and ions in the small intestine. To identify the BBM proteins involved in epithelial cell maturation along the crypt-villus axis, enterocytes were sequentially isolated from the villus tip to the crypt of the jejunum from 21-day-old suckling piglets. After preparation of BBM vesicles, we ...

In the rabbit small intestine, there are three functionally different brush-border membrane (BBM) anion/HCO3- exchangers: 1) Cl/HCO3- exchange on the BBM of villus cells responsible for coupled NaCl absorption; 2) Cl/HCO3- exchange on the BBM of crypt cells possibly involved in HCO3- secretion; and 3) short-chain fatty acid (SCFA)/HCO3- exchange on the BBM of villus cells, which facilitates SCF...

Background: Aim: To review the usefulness of chorionic villus sampling for prenatal diagnosis of thalassaemia with focus on risk of miscarriage and stillbirth in Indian women and thus provide local data for counseling the prospective parents in similar situation. Methods: This retrospective study reviewed the pregnancy outcome of 362 patients with thalassaemia who underwent transabdominal chori...

An early pregnancy counselling clinic was introduced to improve the uptake of prenatal diagnosis and to offer chorionic villus sampling to women aged 38 and over by their expected date of delivery. Ninety eight (62%) unselected older mothers were seen before 11 weeks' gestation, and 23 (32%) of those with viable pregnancies elected to undergo chorionic villus sampling compared with 38 (52%) ele...

This study evaluated the effects of live yeast (LY, Saccharomyces cerevisiae) on growth performance, nutrient digestibility, immune function, antioxidant status and intestinal morphology broilers. A total 224, 1 day-old broilers were assigned 4 treatments (7 replications, 8 chicks each) fed a basal diet control group (CTR); antibiotic (CTC) diets with chlortetracycline at 75 mg/kg; LY-1 LY-2 gr...
