Figure 3.

Effect of ginsenoside Rb1 on the relative levels of intracellular reactive oxygen species (ROS) in Schwann cells treated with intermittent high glucose.

ROS were measured by flow cytometry, and fluorescence intensity was analyzed. (A) Representative flow cytometric images. (B) Fluorescence intensity analysis. The value of the control cells was designated as 1.

Data are expressed as mean ± SEM for each group of cells based on three separate experiments. ^aP < 0.05, ^bP < 0.01, vs. control group; ^cP < 0.05, ^dP < 0.01, vs. intermittent high glucose (IHG) group (one-way analysis of variance followed by Student-Newman-Keuls test).
