Figure 1. Effect of cannabidiol (CBD) on nitric oxide production and cell viability of lipopolysaccharide (LPS)-stimulated RAW 264 cells. Cells were incubated with the indicated concentrations of CBD and 200 ng/ml LPS for 24 h. The final concentration of the samples incubated with LPS is indicated. A: The level of nitric oxide (NO) in the culture medium was measured using the Griess reaction. B: Cell viability was measured using a Cell Counting Kit-8. Data are presented as the mean±standard deviation (n=3-4). Significantly different at: *p<0.05 and ***p<0.001 compared to samples without CBD.
