Small-intestinal mucosa in pseudoobstruction syndromes
The American Journal of Digestive Diseases, 1978The purpose of this investigation was to determine the frequency and severity of small intestinal mucosal damage in pseudoobstruction syndromes. One hundred eighty-nine interpretable biopsies from 12 patients were blindly reviewed by two investigators. The underlying disorders were scleroderma in 7 and idiopathic intestinal pseudoobstruction in 5.

Regeneration of intestinal mucosa after irradiation
Cancer, 1971Radiobiological techniques may be used for determining the size of a population of cells capable of indefinite proliferation (clonogenic cells). In normal “steady-state” proliferative tissues, such as intestinal mucosa, clonogenic cell numbers remain constant through the continuous loss of cells.

UDP-glucuronosyltransferases in human intestinal mucosa
Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1998While UDP-glucuronosyltransferases (UGTs) are known to be expressed at high levels in human liver, relatively little is known about extrahepatic expression. In the present study, UGT2B family isoforms involved in the glucuronidation of steroid hormones and bile acids have been characterized in microsomes prepared from jejunum, ileum and colon from six ...

Cytotoxic Lymphocytes in Human Intestinal Mucosa
1987Although cytotoxic lymphocytes have been well studied and characterized in the peripheral blood, the nature and function of these effector cells in human gut mucosa is still unclear. Previous studies have suggested that human intestinal lamina propria lymphocytes (LPL) exhibit mitogen induced cellular cytotoxicity and antibody-dependent cell-mediated ...

Morphogenesis of rabbit small intestinal mucosa
American Journal of Veterinary Research, 1982SUMMARY The sequential morphologic changes of rabbit small intestinal mucosa were studied from primodial stage to birth in 86 fetuses and during the early days of life in 18 rabbit newborns. In 13-day-old fetuses, the epithelium was flat and stratified. By the 17th day, epithelial ridges were formed.

Serotonergic Integration In the Intestinal Mucosa
Current Pharmaceutical Design, 2020Mucosal serotonin (5-HT) is a key paracrine signaling molecule in the integrated physiology of enterochromaffin cells, enteric mast cells, spinal afferent nerves and the enteric nervous system (ENS). Enterochromaffin cells release 5-HT as a paracrine signal to enteric mast cells, spinal afferents and neurons in the ENS.

Studies on Hog Intestine Mucosa Peroxidase
European Journal of Biochemistry, 1971A method has been developed for isolating and purifying peroxidase from hog intestinal mucosa. The enzyme exhibits an absorbance ratio A417 nm/A280 nm of 0.906.Studies on the homogeneity of intestinal peroxidase by electrophoresis on polyacrylamide gel and cellulose acetate strips showed its high degree of purification; the enzyme showed a single band ...

Potassium transport by flounder intestinal mucosa
American Journal of Physiology-Renal Physiology, 1984We studied the mechanisms of K transport across an epithelium in which NaCl absorption is mediated primarily by Na/K/Cl cotransport at the apical membrane. Rubidium served as a reliable K substitute; under control conditions, both K and Rb were actively secreted.

Cholesterol esterase activity of human intestinal mucosa
Digestive Diseases and Sciences, 1985It has been suggested that cholesterol absorption in humans is dependent on bile acid pool composition and that expansion of the cholic acid pool size is followed by an increase of the absorption values. Similar observations were reported in rats, where the increase of cholesterol absorption, after trihydroxy bile acid feeding, seems to be due to the ...
