摘要

Granulocytes were harvested from each of five healthy male volunteers once by continuous flow centrifugation with the IBM-Aminco Celltrifuge, and once by adhesion filtration leukapheresis with nylon fiber. Granulocyte recovery and purity were significantly better with the filtration leukapheresis system than with the continuous-flow centrifugation. Measurements of trypan blue dye exclusion and muramidase activity were similar to those in control granulocytes regardless of the method of isolation. Granulocyte-stimulated oxygen consumption was diminished in granulocytes prepared by the adhesion filtration method, but normal in those prepared by continuous flow centrifugation with the IBM-Aminco Celltrifuge.
