Figure 4. Ginsenoside Rg1 decreased lipopolysaccharide (LPS)-induced increase in reactive oxygen species (ROS) activity. HK-2 cells were treated with 150 μM of ginsenoside Rg1 and/or 5 μg/mL of LPS, and then ROS activity was detected. Data are reported as means±SD (n=3). ^**P<0.01 and ^***P<0.001 (ANOVA).
