    Journal: Transfusion; 1985; 25(4):343-8. PubMed ID: 4024233.
    Abstract:
    We studied a French modified fluid gelatin (MFG), substituting it for hydroxyethyl starch (HES) in leukapheresis procedures using three currently available blood cell separators, and observing its effects on the function of platelets and granulocytes. As a cell-collecting agent, we found MFG to be as effective as HES with intermittent flow centrifugation (Haemonetics), and slightly less so with one continuous flow device (IBM 2997). MFG was clearly less effective than HES with the Fenwal CS-3000 continuous flow separator, although we have reason to believe it would be possible to improve efficiency with this machine by changing the operating variables. Tests of platelet and granulocyte function showed negligible alteration with either agent and no difference between them. MFG disappears much more rapidly from the circulation than HES (after a single injection, it is undetectable by the third day). Reaction frequency with MFG was about the same as that of HES, with perhaps somewhat more frequent allergic manifestations.
