Ultrastructure of the Small Intestinal Mucosa

Malignancy and the Small-intestinal Mucosa.

The observations presented here suggest that malignancy anywhere in the body may be accompanied by a secondary change in the small-intestinal mucosa, including the flattened appearance that is usually seen in idiopathic steatorrhoea. The reverse of this association, that idiopathic steatorrhoea may be complicated by a reticulosis, has been reported by Gough et al. (1962). They described four ca...

Significance of a Flat Small-intestinal Mucosa.

Glycoprotein Biosynthesis in Small Intestinal Mucosa

An active multiglycosyltransferase system involved in the transfer of N-acetylgalactosamine, N-acetylglucosamine, and galactose to various glycoprotein acceptors was found in the rat small intestinal mucosa. The present studies are concerned with the subcellular localization of these glycosyltransferases. Satisfactory isolation of smooth and rough surfaced microsomes from the intestinal mucosa ...

Effect of dietary fat on the small intestinal mucosa.

The presence of food within the small intestinal lumen promotes mucosal cell proliferation. To define the trophic role of triglycerides, three groups of eight female Wistar rats were isocalorically fed for four weeks with either Vivonex, or Vivonex with 50% calorie substitution with an essential fatty acid mixture, or Vivonex with 50% calorie substitution with a saturated fatty acid mixture. Al...

Acid proteinase from the small intestinal mucosa of rats.

In our previous work we isolated a cathepsin from the intestinal mucosa of pig and described some of its properties 1 . It is known that proteins are species — and organ speci f ic 2 . W e were interested to know whether this specificity could have any effect on some characteristics of mucosal cathepsin. That such effects may by possible is supported by the results of RANGEL and LAPRESLE 3 who ...
