Effect of bee pollen on NO production in LPS-stimulated RAW 264.7 cells. The production of NO was detected and analyzed using Griess reagent. RAW 264.7 cells were incubated for 24 h at 37°C in medium containing three different concentrations of the bee pollen extract of each EtOH BP and Water BP and LPS (1 μg/ml). Results were expressed as an inhibition % of control (solvent-treated samples).
