Interactions between acidified dispersions of milk proteins and dextran or dextran sulfate

Sodium-Induced Colitis through Inhibition Fos Proteins Suppress Dextran Sulfate

Nature of interaction of dextran sulfate with lecithin dispersions and lysolecithin micelles.

Lecithin and lecithin/cholesterol dispersions as well as lysolecithin micelles were used to provide basic information on the mechanism of the interaction of zwitterionic phospholipids with dextran sulfate. The addition of dextran sulfate to lecithin dispersions or lysolecithin micelles in the presence of Ca2+ produced insoluble complexes. At each Ca2+ concentration, the amount of insoluble comp...

Calycosin attenuates dextran sulfate sodium (DSS)-induced experimental colitis

Objective(s):Inflammatory bowel disease (IBD) results from dysregulation of intestinal mucosal immunity. It is an incurable disease that affects millions of people worldwide. Developing new strategies for the treatment of colitis has been a major challenge. Here, we report the effect of calycosin, a plant-derived flavonoid, in successfully managing colitis in murine model. Material and Methods:...

Interaction of Fibrinogen with Dextran Sulfate

Interactions of fibrinogen with dextran sulfate, dextran, and carboxymethyl cellulose were investigated by turbidity measurement, chemical analysis, and electrophoresis. Dextran sulfate and fibrinogen combined even in the physiological pH region where both of them have negative net charges, and formed a precipitate and soluble complex. Since no complex formation was observed in the case of dext...

Effects of dextran sulfate on aprotinin activity.

Dextran sulfate has an action on aprotinin activity similar to that seen with heparin: preincubation of dextran sulfate with aprotinin enhanced the inhibitory effect of aprotinin on the esterolytic activity of trypsin, but did not change the effect on the proteolytic activity of trypsin or on the esterolytic and proteolytic activities of chymotrypsin. The enhancing effects of heparin and dextra...
