Tetrandrine Inhibits Titanium Particle-Induced Inflammatory Osteolysis through the Nuclear Factor-κB Pathway

Figure 3

Tetrandrine (Tet) inhibits the expression of proinflammatory cytokines. (a) Immunohistochemical staining of tumor necrosis factor (TNF)-α. (b) Immunohistochemical staining of interleukin (IL)-1β. (c) Immunohistochemical staining of IL-6. The mean density for TNF-α, IL-1β, and IL-6 were quantified (, compared with the vehicle group; per group). Black arrows indicate positive expression, respectively.
