Jones and Wilkie, in a recent paper, describe a study of the structures of four dextrans currently being used as synthetic, blood-plasma expanders. These dextrans were shown to contain the (1 — 3)-linkage as the major branch point, with a small proportion of (1 —> 4)-linkages present, in addition to the normal (1 — 6)-linkages. These conclusions may, however, be attributable to incomplete methyMion of the polysaccharides investigated.

A large number of polysaccharides are used in industry, for example, as fibers (cellulose), as foodstuffs (amylose), as industrial thickeners (e.g., pectin, guar), and for medical purposes (blood plasma expanders, blood anticoagulants, etc.). 

Increased vascular permeability has been demonstrated, with extravasation of blood plasma expanding the interstitial fluid space and— because of the lack of functional lymphatics— drastically increasing the hydrostatic pressure in the tumor interstitium.

PoIy(N-vinylpyrrolidinone) (PNVP) has been used in medical applications for many years. Its history can be traced back to the Second World War where in its un-crosslinked form it was used as a blood plasma expander (I). This un-crosslinked PNVP when added to iodine forms a complex, in solution this complex is better known as Povidone-iodine or by its trade name Betadine , a surgical antiseptic. PNVP is also used as a binder in many pharmaceutical tablets as low molecular weight PNVP can be removed from the body by the kidneys. These polymers have also been investigated for use as wound dressings, drug... 

As an example of a water-soluble biopolymer that can be entrapped in and released from the elastin microgels we choose a dextran that has been used as a blood plasma expander. Loading of the microgels with the model drug dextran was achieved by addition of dextran to the inverse emulsion during microgel...

CSF was introduced in 2004 for the fractionation of two different commercially important polymers. One was hydro-xyethyl starch (HES) - a derivative of a biopolymer used as blood plasma expander - and the other was Novolac - a synthetic polymer used as photoresist. One of the reasons why one would like to fractionate HES lies in the fact that short-chain material is inefficient because it leaves the body...
