Brush border enzymes in coeliac disease: histochemical evaluation.
Two hundred and ninety four duodenal and jejunal mucosal biopsy specimens from patients with coeliac disease, treated and untreated, and other conditions were examined histologically and by histochemical staining for five peptidase and three disaccharidase enzymes to determine profiles of activity. Suppression of activity paralleled the histology with the following enzymes: lactase, trehalase, ...
متن کاملFetal Forms of Enzymes of Intestinal Brush Border
The surface membrane of the small intestine comes into contact with luminal nutrients, organisms, drugs and foreign antigens. The natural frontier between the body and the intestinal content is represented by the glycoproteins of the brush border membrane, which act as receptors, carriers and hydrolytic enzymes. Developmental variability of these glycoproteins may therefore regulate intestinal ...
متن کاملTransport of nutrients into the renal brush border membrane vesicles as marker in evaluating the role of antipili antibodies in modulation of ascending pyelonephritis in rats.
The uptake of D-glucose, L-aspartate, L-lysine and L-proline was investigated in renal brush border membrane (BBM) vesicles prepared from control, infected or passively-immunized-infected rats. Except L-aspartate, a progressive decrease in the uptake of these nutrients in both infected and immunized-infected groups during the course of infection was observed, but the changes were less apparent ...
متن کاملActive alanine transport in isolated brush border membranes.
Uptake of L-alanine against a concentration gradient has been shown to occur with isolated brush border membranes from rat small intestine. An alanine transport system, displaying the following characteristics, was shown: (a) L-alanine was taken up and released faster than D-alanine; (b) Na+ as well as Li+ stimulated the uptake of both stereoisomers; (c) the uptake of L- and D-alanine showed sa...
متن کاملbrush-border membrane vesicles
The characteristics of hypoxanthine transport were examined in purified brush-border membrane vesicles isolated from guineapig kidney. Hypoxanthine uptake in the vesicles was specifically stimulated by both Na+ and an inside-negative potential, resulting in a transient accumulation of intravesicular hypoxanthine. Na+-dependent hypoxanthine influx was saturable (apparent Km 4.4 + 2.1 ,uM, Vmax 1...
