Immuno-stimulatory effect of Fraction I and III of the AQ, PS extracts of ginseng and Cold-Fx. Murine macrophages (RAW 264.7 cells) were treated with Fraction I and III of AQ ginseng extract, PS extract of ginseng and Cold-Fx. (0, 20, 50, 200 μg/ml), LPS (1 μg/ml) for 24 hours and the NO, TNF-α and IL-6 contents of the culture supernatants were determined. Three independent experiments were performed and the data were shown as mean ± SD. Datasets were evaluated by ANOVA. *Values P < 0.001 compared to the untreated (vehicle) control were statistically significant.
