Tetrandrine (Tet) prevents Ti particle-induced chronic inflammation and osteolysis in vivo. (a) H&E-stained images of the tissue specimen sections in each group observed via light microscopy. (b) Membrane thickness were quantified. (c) TRAP-stained images of the tissue specimen sections in each group observed via light microscopy. (d) TRAP-positive cells were quantified. (e) Transmission electron microscopy (TEM) images of cells in the implanted bones and pouches around Ti particles. The air pouch membrane thickness (μm) and TRAP-positive cell numbers were quantified (∗p < 0.05, ∗∗p < 0.01 compared with the vehicle group; n = 5 per group). M: membrane; B: bone; H&E: hematoxylin and eosin; TRAP: tartrate-resistant acid phosphatase. The red arrows indicate TRAP-positive cells.
