Figure 8. Effects of ginseng polysaccharide on the growth of influenza virus in vitro.

Figure 8

A) Effects of ginseng polysaccharide on influenza A/PR8 virus. A diluted influenza A/PR8 virus (approximately 20,000 plaque forming units/ml) was mixed with different concentrations of GP (0, 500, 1000 µg/mL) and cultured for 3 days. B) Effects of ginseng polysaccharide on 2009 H1N1 pandemic influenza A/California/2009 virus. A diluted influenza A/California/2009 virus (approximately 4,000 plaque forming units/ml) was mixed with different concentrations of GP (0, 100, 200 µg/mL) and cultured for 5 days. The growth of viruses (A/PR8 virus, A/California/2009 virus) was determined by hemagglutination activity using chicken red blood cells, and presented as percentages compared to the controls (the wells without GP).
