HAECs affected neutrophil functions time- and dose-dependently. The HAECs-induced inhibition of respiratory burst of neutrophils differed in the presence of different number of HAECs and diminished by time. However, the ratio groups do not differ statistically significant in their degree of change in the OBI over time (Repeated measurement ANOVA, n=5, p=0.104) (A). The phagocytic activity of neutrophils were raised considerably in all ratios of HAECs to neutrophils, and the lowest ratio caused the highest level; it also showed an increase by time. Additionally, there was an interaction between time and cell ratio; the effect of cell numbers on the phagocytosis varied over time (Repeated measurement ANOVA, n=5, p=0.034) (B).
