Dextran is a complex branched glucan (polysaccharide made of many glucose molecules) composed of chains of varying lengths (from 3 to 5000 kilodaltons). it is produced from sucrose by Leuconostoc mesenteroides and related organisms and from dextrins by other bacteria.  Dextran 70 (relative molecular mass 70000), appearance white crystal or powder, like albumin, it contributes to the colloid oncotic pressure of plasma. Unlike albumin, dextran 70 prevents platelet aggregation and facilitates fibrinolysis. It can be used as a stabilizing coating to protect metal nanoparticles from oxidation .Dextrans are long-chain glucose polysaccharides of various relative molecular masses.

Function

Dextran 70 is used medicinally as an antithrombotic (antiplatelet), to reduce blood viscosity, and as a volume expander in hypovolaemia.medicine for blood volume expansion, improved plasma colloid osmotic pressure, increase of plasma volume and maintain blood pressure, prevent shock, can prevent the red blood cell and platelet aggregation, reduce blood viscosity, which has the effect of improving microcirculation.

1) Anti-anemia drugs. For iron deficiency anemia.
2) Blood-supply drugs, Dextran is mainly used to increase plasma capacity, maintain blood pressure, and to resist shock. It can be used to replenish blood volume and maintain blood pressure. If burns, trauma, trauma and other hemorrhagic and excessive blood loss caused by the first aid.
