Figure 5: Comparison of CD25 FITC and CD127 PE among CD4-positive T cells (Treg cells) before and after treatment. There were significant differences of Treg cells between before treatment and after treatment in the 400 group and 800 groups ( by Wilcoxon’s signed rank sum test), but there was no significant difference of Th2 cells in the 200 group.
