Figure 3: Suppression of IL-6 (A) and TNFα (B) secretion by peritoneal macrophages by S. indicum extract (1-100 μg/mL) assessed by ELISA. For S. indicum extract-treated macrophages that were cultured in the absence of LPS plus IFNγ, statistical significance was determined in comparison to vehicle-treatedmacrophages. For S. indicum extract-treated macrophages that were cultured in the presence of LPS plus IFNγ, statistical significance was determined in comparison to LPS- and IFNγ-treated macrophages (n = 6). Data are expressed as mean ± SEM. *P < 0.05 and **P < 0.01. The error bars represent SEM values. |
