Antibiofilm and Antioxidant Activity of Propolis and Bud Poplar Resins versus Pseudomonas aeruginosa

Figure 8

Anti-inflammatory activity of propolis and bud poplar resins extracts. TNF-α and IL-1β production by PBMC in response to LPS in presence of propolis or bud poplar resins extracts. PBMC were stimulated for 4 h with LPS (1 μg/mL) and then treated overnight with extracts at the concentration of 10 and 50 μg/mL. After incubation, supernatants were recovered and tested for the presence of TNF-α and IL-1β by ELISA assay. Data are expressed as mean ± SEM for three samples pooled from three independent experiments. (propolis plus LPS-treated cells versus LPS-treated cells) and (bud poplar resins extract plus LPS-treated cells versus propolis extract plus LPS-treated cells). Differences were analyzed by test.
