Time-dependent viscoelastic properties along rat small intestine

Histomorphometric changes of small intestine in pregnant rat

Food intake of rats increases during pregnancy. This requires changes in the structure of the small intestine to absorb additional food. The aim of the present study was to investigate the morphological changes in the layers of small intestine in rats during pregnancy. Duodenum, jejunum and ileum of 18 pregnant Sprague-Dawley rats (day 7, 14 and 21 of pregnancy) were collected. Villous height a...

Experimental and regional variations in Na+‐dependent and Na+‐independent phosphate transport along the rat small intestine and colon

Despite the importance of extracellular phosphate in many essential biological processes, the mechanisms of phosphate transport across the epithelium of different intestinal segments remain unclear. We have used an in vitro method to investigate phosphate transport at the brush border membrane (BBM) of intact intestinal segments and an in vivo method to study transepithelial phosphate absorptio...

Regulation of sucrase-isomaltase gene expression along the crypt-villus axis of rat small intestine.

The expression of sucrase-isomaltase mRNA was investigated along the crypt-villus axis of rat small intestine using differentially isolated cells and in situ hybridization. A partial rat sucrase-isomaltase cDNA was cloned which coded for a protein that was predicted to be 88% homologous to those encoded by the rabbit and human cDNAs. Southern blot analysis of rat genomic DNA indicated that the ...

calcium binding protein along the small and large intestine ofman

The distribution of the 10000 molecular weight calcium binding protein along the human small and large intestine was studied using an enzyme linked immunoadsorbent assay. Small intestinal mucosal samples were obtained from the duodenal bulb, the second and third part of the duodenum and at about 50 cm intervals from jejunum and ileum of five whole small intestines of necro-kidney donors. Mucosa...
