The jejunal mucosa in kwashiorkor.

The jejunal mucosa in kwashiorkor.

The 'tissue paper' intestine of patients with severe kwashiorkor is well known to tropical pathologists and it is usually considered to involve all coats of the intestinal wall. However, histological study of the small gut mucosa in man has been very difficult until the advent of peroral biopsy (Shiner, 1956). This paper reports a series of 17 infants with kwashiorkor whose jejunal mucosa was s...

Electron microscopic study on the jejunal mucosa in human cholera.

Small intestinal mucosa obtained from six fasting patients with cholera by a peroral biopsy technique was studied with the electron microscope. The cultures of their rectal swabs were all positive for Vibrio cholerae. In the absorptive cells, large pseudopod-like cytoplasmic processes with deformed microvilli or without microvilli (blebs) projected into the intestinal lumen from the apical cell...

Intraepithelial lymphocytes in the jejunal mucosa of malnourished rats.

Intraepithelial lymphocytes (IEL) have been counted in the jejunal mucosa of adult Wistar rats submitted to a protein-free diet for 84 days and of a control group receiving a 20% casein diet, in order to evaluate the effect of protein deprivation. Relative counts (IEL/100 epithelial cells), absolute counts (number of IEL per millimetre of muscularis mucosae), and the proportion of lymphocytes c...

Jejunal disaccharidase activities in children with marasmus and with kwashiorkor. Response to treatment.

Hereditary Sucrose Intolerance: Levels of Sucrase Activity in Jejunal Mucosa.

Though the amylase of duodenal juice hydrolyses the polysaccharides of the diet to oligosaccharides and disaccharides, the final cleavage of the latter to the monosaccharides, which is essential for absorption, is almost entirely effected by specific enzymes located in the intestinal mucosa. An inherited deficiency of intestinal lactase was first suggested as a possible cause of chronic diarrho...
