Background: The application of nano-particles (NPs) in various industries is growing. Since their toxicity is not clearly understood, they can cause adverse effects on the environment. The aim of this study was to evaluate the histopathological effects of iron oxide nano-particles on the small intestine of common carp, Cyprinus carpio. Methods: Four experimental treatments were designed (15 ...

This experiment was conducted to determine the effects of dietary myrtle essential oil on small intestinal morphology and microbiology of broiler chickens. Two hundred day-old broiler chickens (Ross 308) were allocated to 5 treatments, 4 replications with a completely randomized design. The diets were supplemented with: no myrtle essential oil (control), each of myrtle essential oil at levels o...

The patient is a 12 year-old girl who has been suffering from episodes of in testinal obstruction since she was 6 years old, leading to severe malnutrition, malabsorption and growth retardation.  Repeated radiological examinations revealed esophageal achalasia, gastric distention, marked small intestinal and mild colonic dilatation. Transmural biopsies from small and large bowels showed normal ...

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...
