Studies on dextran and dextran derivatives. I. Properties of native dextran in different solvents
Biopolymers, 1964AbstractLight‐scattering, sedimentation, viscosity, and reducing power measurements have been carried out on a sample of native dextran from Leuconostoc mesenteriodes B‐512. The results are discussed in relation to the structure, polydispersity, and branching of the polysaccharide.

The Effect of DEAE Dextran, Dextran Sulfate and Dextran on Porcine Mixed Lymphocyte Reaction
Zentralblatt für Veterinärmedizin Reihe B, 2010Summary The polycation DD moderately stimulated lymph node lymphocytes from pigs and considerably enhanced MLR. The latter effect was especially marked when the reaction was in the descending phase. The MLR was dependent on cell number, and there was a strong correlation between optimal effective DD dose and cell number.

Histamine release induced by dextran: The nature of the dextran receptor
European Journal of Pharmacology, 1982Dextrans of molecular weight 10(4) to 2 x 10(6) induced histamine release from rat peritoneal mast cells in the presence of calcium (1 mM) and phosphatidyl serine (10 micrograms/ml). Glucose and low molecular weight dextrans inhibited the histamine release induced by high molecular weight dextrans but the inhibition could not be explained in terms of a

Dextran Therapy in Thrombophlebitis
JAMA: The Journal of the American Medical Association, 1965The value of dextran has increased far beyond that of a volume expander. Low-molecularweight fractions (average molecular weight [mol wt] 40,000) have the ability to disrupt red cell agglutination and in some states to improve blood flow 1 ; this has proved useful in ischemic and low flow situations.

Corneal Cryopreservation with Dextran
Cryobiology, 2001Different methods of corneal cryopreservation have been introduced, those employing intracellular cryoprotectants such as Me2SO or glycerol being the most widely favored. We investigated the influence of several freeze-thaw trauma variables on the survival of porcine endothelial monolayers when employing the extracellular cryoprotective agent dextran ...

Anaphylactic Reaction to Dextrans
New England Journal of Medicine, 1968DEXTRANS have been used extensively as plasma expanders1 and for the treatment of venous thrombosis and emboli,2 traumatic occlusion of vessels,3 peripheral ischemia4 and arterial emboli.5 Despite a large clinical experience with this material in Europe and America, no serious reactions have been reported.
