Abstract:
Objective: To discuss the effect of Gandou decoction (GDD) on the immune index of spleen in TX mice of Wilson's disease model. Method: The mice were divided into normal group, model group and GDD or tetrathiomolybdate(TM)treatment group, with 20 mice in each group. Each group was fed in various ways for 30 successive days. Normal group:10 normal DL mice were randomly selected and feed normally. Model group:20 TX mice were randomly selected and feed with 2 mL·kg-1·d-1ig saline by gavage twice per day. GDD or TM treatment group:80 TX mice were randomly selected and feed with 2 mL·kg-1·d-1 ig Gandou decoction 22,44,66 g·kg-1 or tetrathiomolybdate by gavage twice per day. ICP-MS was used to compare the expressions of trace elements inside the mice's spleens, flow cytometry was applied to detect the mice T lymphocyte subsets of splenic tissue CD4+, CD8+, CD4+/CD8+, and Western blot was used to detect the expressions of interferon-γ (IFN-γ), tumor necrosis factor-α (TNF-α), interleukin-2 (IL-2), interleukin-8 (IL-8), interleukin-17 (IL-17) and interleukin-18 (IL-18). Result: Flow ICP-MS results showed that GDD can reduce Cu of mice's spleen, flow cytometry results showed that CD4+and CD8+in model group were increased than those in normal group (P<0.01), and CD4+/CD8+was decreased (P<0.01); compared with model group, CD4+and CD8+in middle and high-dose GDD groups were decreased (P<0.01), and CD4+/CD8+was increased. According to Western blot detection, compared with normal group, the expressions of IL-2, IL-8, IL-17, IL-18, TNF-α and IFN-γ in the model group were increased (P<0.01); compared with model group, the expressions of TNF-α, IFN-γ, IL-2, IL-8, IL-17 and IL-18 in the GDD middle and high or TM group were decreased (P<0.05, P<0.01). Compared with model group, the expressions of IL-2, IL-8, IL-17 and TNF-α in the GDD low were decreased (P<0.05). Conclusion: Spleen of TX mice shows the cellular immunity hyperfunction, which is mainly dominated by the negative immunoloregulation. GDD has a certain effect in regulating cellular immunity hyperfunctional state of TX mice, but it's difficult to thoroughly change the negative immune regulation.
