Evaluation on Cartilage Morphology after Intra-Articular Injection of Titanium Dioxide Nanoparticles in Rats
Figure 8
Photograph of knee joint cavity in rats after intra-articular injection of TiO2 nanoparticles. Control: the smooth and moist knee cavity; exposed: the white particles-xanthoproteic complexes (arrows) in the synovial joint capsule of exposed rats, which indicate the deposition of TiO2 particles. With the time prolong from the postexposure days 1 to 30, the deposited particles-xanthoproteic complexes were reduced. P: patellar; F: femur.
