Figure 2. Changes of cytokines, transaminase and hydroxyproline content in each group in in vivo experiments. (A–F) Analysis of cytokines (IFN-γ, IL-4, IL-5 and IL-13) and serum ALT, AST in each experimental group and each control group. (G) Analysis of hydroxyproline content in each group. At least 3 rats could be used to repeat the experiment at each week point. *p < 0.05, **p < 0.01, ***p < 0.001.
