Analysis of S100 calcium binding protein A9 (S100A9) levels in peripheral blood cells and serum. Two-dimensional SDS-PAGE gel images of peripheral blood nucleated cells in patients with and without HBO therapy (A). Decreased S100A9 protein spots in the HBO group (B). Tandem mass spectrometrograms (C) and attributes (D) of S100A9. Decreased serum S100A9 levels in patients with osteonecrosis of the femoral head (ONFH) upon HBO therapy (E). Data are expressed as mean ± standard errors calculated from 5 patients. * p < 0.05. ONFH, osteonecrosis of the femoral head; HBO, hyperbaric oxygen. Red circles, patients with ONFH before HBO therapy; Blue squares, patients with ONFH upon HBO therapy.
