摘要

We investigated the effects of nickel oxide nanoparticles (NiONPs) on the pulmonary inflammopathology. NiONPs were intratracheally installed into mice, and lung injury and inflammation were evaluated between 1 and 28 days. NiONPs caused significant increases in LDH, total protein, and IL-6 and a decrease in IL-10 in the BALF and increases in 8-OHdG and caspase-3 in lung tissues at 24 h. Airway inflammation was present in a dose-dependent manner from the upper to lower airways at 24 h of exposure as analyzed by SPECT. Lung parenchyma inflammation and small airway inflammation were observed by CT after NiONP exposure. 8-OHdG in lung tissues had increased with formation of fibrosis at 28 days. Focal adhesion was the most important pathways identified at 24 h as determined by protemics, whereas glutathione metabolism was the most important identified at 28 days. Our results demonstrated the pulmonary inflammopathology caused by NiONPs based on image-to-biochemical approaches.
