Figure 1. SOG inhibits the release of inflammatory cytokines.

Indicated concentrations of SOG (25, 50 and 100 μM) were added to RAW 264.7 cells stimulated by LPS. Supernatant medium was collected after 6 h of incubation, and TNF-α (A) and IL-6 (B) were detected by ELISA. The results of three independent experiments were expressed as means ± SEM. ^###P < 0.001 versus blank group (LPS-unstimulated cells), *P < 0.05, **P < 0.01 and ***P < 0.001 versus group treated by LPS.
