[The effect of the cell separation procedure on neutrophilic granulocyte function. I. Research on the morphology and phagocytosis behavior of isolated granulocytes].

The investigations were aimed at detecting the impact of various cell separating techniques on the morphology and function of neutrophilic granulocytes. Methodically simple cell separating techniques were used, such as spontaneous sedimentation of ACD-AG blood and mechanically defibrinated blood and a flotation technique which makes use of cell isolation by means of a separating solution and centrifugation. Granulocytes which were isolated by the cell separator Haemonetics M 30 for therapeutic purposes and which, according to data in literature, are not damaged by cell separating techniques were used as reference cells. The electronic-optical evaluation of granulocyte morphology and the in vitro investigation of the phagocytic capacity for rice starch (ingestion rate) of differently isolated granulocytes were made after cell separation.
