Fig. 2From: Epimedium sagittatum inhibits TLR4/MD-2 mediated NF-κB signaling pathway with anti-inflammatory activityCytotoxicity of YYHs on RAW 264.7 cells. Cells were treated in the presence of YYHs or in combination with LPS (1 μg/mL) for 24 h. Cell viability was determined by MTT assay (black bar, YYHs treated; white bar, YYHs+LPS treated). Compared with the control, #P < 0.05, ##P < 0.01. Compared with LPS group, *P < 0.05, **P < 0.01Back to article page
