The microanatomy of the intestinal epithelium in the Chinese soft-shelled turtle (CST) was studied by light and transmission electron microscopy (TEM). The small intestinal epithelium (SIE) was single layered or pseudostratified. The enterocytes contained mitochondria or mitochondria and lipid droplets. The enterocytes were arranged tightly in the apical parts of epithelium and connected by des...

Under high altitude conditions, the effects of vitamin E (α-tocopherol) on growth performance, intestinal morphology (villus size and type), and absorptive surface area of broiler chickens were evaluated. Chickens were fed diets supplemented with 0, 100, 200 or 400 IU/kg vitamin E for 42 days. On days 14, 28 and 42, birds were sacrificed and three segments of small intestine were dissected. The...

Objective- This study investigated the effect of amlodipine on intestinal ischemia-reperfusion injury in ratsDesign-Experimental studyAnimals-Fifteen male Sprague-Dawly rats weighing 200-220gProcedure- Rats were randomly divided into 3 groups: IR group (operation with clamping), sham group (operation without clamping), and IRA group (operation with clamping and 5mg/kg amlodipi...

The dopamine beta-hydroxylase promoter has been shown to direct expression of the reporter gene product, beta-galactosidase, to enteric neurons and putative embryonic neuroblasts in transgenic mice (Mercer et al., 1991; Kapur et al., 1991). In this paper, expression of the transgene, D beta H-nlacZ, in the gastrointestinal tract is characterized in more detail in wild-type mice and mice which a...

Intestinal stem cells (ISCs) are a group of rare cells located in the intestinal crypts which are responsible for the maintenance of the intestinal homeostasis and intestinal regeneration following injury or inflammation. Lineage tracing experiments in mice have proven that ISCs can repopulate the entire intestinal crypt. It is noteworthy that in such experiments, only a subset of intestinal cr...

  Absract   Intestinal malrotation is a general term used for any deviation from normal embryonic GI tract rotations. This abnormality, denotes a spectrum of conditions (non rotation, incomplete rotation) that according to the severity of anatomic consequence, can result in complications found in infancy, childhood, adolescence, adulthood or old age. This article, reports another case of intest...

this investigation was designed to determine the effect of intact ovalbumin and mannose-conjugatedovalbumin on the prevention of salmonella typhimurium adherence to the epithelium of small intestine ofchickens. mannose-conjugated ovalbumin was produced by maillard-type reaction between chickenovalbumin and d-mannose at 60°c. the results revealed that incubation up to 96 hrs caused the highestam...
