Figure 2 Phagocytosis by neutrophils and monocytes in chronic lymphocytic leukaemia; (a) leukocyte DNA was stained and analyzed by flowcytometry using FL2. DNA signal was expressed as single peak with mean fluorescence intensity (MFI) 6000. Phagocytosis by (b) neutrophils or (c) monocytes was analysed by flow cytometry using FL1; histogram for 0°C sample (green colour), at 37°C for 10 min (blue colour). (d) Histogram shows phagocytosis cell percentage (right) and phagocytosis MFI (left) by neutrophils and monocytes. Data are represented as mean±SD. *Statistical significance difference. IA=newly diagnosed, IB=treated, II=control group. **Moderately significant. ***Highly significant.
