Figure 1: Effects of a high-molecular weight fraction of Cynanchum auriculatum on (a) cell viability, (b) nitric oxide production, (c) tumor necrosis factor-α production, (d) interleukin-6 production and (e) phagocytic activity in recombinant interferon-γ primed RAW 264.7 murine macrophages stimulated with high-molecular weight fraction of Cynanchum auriculatum (50, 100 and 200 μg/mL). Values with the different letters are significantly different (P < 0.05) |
