Figure 2.
Effect of simvastatin on lipopolysaccharide (LPS)-induced neutrophil recruitment. Healthy human volunteers inhaled 50 μg LPS. Simvastatin or placebo was administered for 4 days before LPS inhalation. Bronchoaveolar lavage fluid (BALF) was obtained 6 hours after inhalation of LPS, and supernatants were analyzed for (A) myeloperoxidase and (B) neutrophil elastase:α-1-antitrypsin complex (NE: α-1-AT). Open bars = placebo; solid bars = simvastatin. Data are shown for the 10 subjects in the placebo group and the 20 subjects in the combined simvastatin group. Data are medians (IQR). * P < 0.05 versus placebo.
