Figure 1.

Comparison of cytokine levels between groups. All samples were centrifuged for 10 minutes at speeds of 2500 RPM and 4000 RPM, and the plasma part of the blood sample was separated after centrifugation. The cytokine levels of all samples were determined by ELISAs, and the data are expressed in pg/mL. Significant differences in cytokine levels were observed between the BCG (n = 68) and ACG (n = 122), CNG (n = 44) and CIG (n = 78), and BCG (n = 68) and CIG (n = 78), P<0.05. There were no significant differences in cytokine levels between the BCG (n = 68) and CNG (n = 44), P>0.05.
