Fig. 7From: Characterization of macrophage activation after treatment with polysaccharides from ginseng according to heat processingEffects of P-WG, P-RG, and P-HPG on nitric oxide (NO) production in RAW 264.7 macrophages. RAW 264.7 macrophages were stimulated with either a P-WG, b P-RG, or c P-HPG at concentrations of 125, 250, 500, or 1000 μg/mL for 22 h. Cell supernatants were harvested for NO production analysis (a–c). All data are presented as mean ± SD, with n = 3, *P < 0.05 and ***P < 0.0001 compared to controlBack to article page
