Fig. 1. Comparison of anti-inflammatory property of Cannabis root and stem extract. (A) Effect of Cannabis root and stem extract on RAW264.7 cell viability. (B) Inhibitory effect of Cannabis root and stem extract on NO production in LPS-stimulated RAW264.7 cell. (C) Inhibitory effect of Cannabis root and stem extract on cytosolic iNOS levels in LPS-stimulated RAW264.7 cell. (D) Densitometric analysis of iNOS protein expression. Results of protein levels were divided by β-actin protein levels and normalized to the non- treated control. NO: nitric oxide, LPS: lipopolysaccharide, iNOS: inducible nitric oxide synthase. *P<0.05 vs non-treated group. †P< 0.05, ††P<0.01 vs LPS-treated control group.
