Dual Stimulus-Dependent Effect of Oenothera paradoxa Extract on the Respiratory Burst in Human Leukocytes: Suppressing for Escherichia coli and Phorbol Myristate Acetate and Stimulating for Formyl-Methionyl-Leucyl-Phenylalanine
Figure 1
Boxplots of the percentage of neutrophils (a) and monocytes (b) producing ROS (NROS [%] and MROS [%], resp.) and a mean fluorescent intensity (MFI) of these cells ((c) and (d)) stimulated with PMA or E. coli after their exposition to the extract (0.1 and 0.25 mg/mL) versus control (without the extract) for PMA and E. coli stimuli. Middle point: median; box: interquartile range; whisker: range (excluding outliers). Significance levels , , and assessed by Wilcoxon’s test are indicated by asterisks.
