The present study was designed to assess the intestinal absorption of D-xylose and jejunal morphometry in rats with iron-deficiency anemia. Male Wistar rats were randomly divided into a control group (diet containing 50 mg Fe/kg, N = 12) and an anemic group (diet containing <5 mg Fe/kg, N = 12). The animals were housed in individual metabolic cages and deionized water and diet were provided ad ...

The differentiated enterocyte of the mammalian small intestine is an excellent model to study the polarized expression of surface membrane proteins in epithelial cells. A number of digestive hydrolases, most of which are major integral membrane proteins, are specifically expressed in the brush-border membrane of these cells and they can serve as molecular markers for the apical membrane domain ...

Chorionic villus sampling (CVS) is a test used for prenatal diagnosis [5]. Safe to perform at an earlier stage in pregnancy [6] than amniocentesis, CVS is another invasive prenatal diagnostic test that can be performed as early as ten weeks after the woman?s last menstrual cycle. While this test does carry some risks, it is generally very effective at predicting heritable diseases during or soo...

BACKGROUND Environmental enteric dysfunction (EED) is widespread throughout the tropics and in children is associated with stunting and other adverse health outcomes. One of the hallmarks of EED is villus damage. In children with severe acute malnutrition (SAM) the severity of enteropathy is greater and short term mortality is high, but the metabolic consequences of enteropathy are unknown. Her...

an experiment was conducted to evaluate the effect of non-starch polysaccharides of barley supplemented with multi-enzyme on growth performance and physiological characteristics of broilers. a total number of 375 one day old ross-308 broiler chickens were allocated randomly to 3 treatments with 5 replicates at 2 rearing period (including 1 to 21 and 22 to 42 days of age) using a crd statistical...

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 ...
