PQ delayed neutrophil apoptosis in a concentration-independent manner.

Abstract

<p>Neutrophil apoptosis was assessed with annexin V-FITC and PI staining followed by flow cytometry. Compared with the control, the doses of PQ (5, 50, or 100 μM) significantly attenuated neutrophil apoptosis at all time points after treatment (6, 12, 18, and 24 h). No difference was found between different concentration groups. *<i>P</i><0.05 compared with control at the same time point.</p
