Abstract
Clinical dextran (viz. a sterile 6 per cent aqueous solution of hydrolysed and deionized dextran for use as a blood plasma extender) is improved by agitating it before the final sterilization with a soluble or insoluble, physiologically harmless, calcium salt such as the carbonate, phosphate, lactate or levulinate and separating insoluble matter.ALSO:Clinical dextran, viz. a sterile 6 per cent aqueous solution of hydrolysed and deonized dextran, for use as a blood plasma extender, is improved by agitating it before the final sterilization with a soluble or insoluble, physiologically harmless, calcium salt, such as the carbonate, phosphate, lactate or levulinate, and separating insoluble matter. The improved dextran does not prolong the normal bleeding time when injected intravenously.
