The effects of BALF from placebo treated rats (BALF-none) and BALF from rats treated with plasma-derived AT (BALF-AT) on survival of Streptococcus pneumoniae in vitro. (a) After five hours outgrowth of S. pneumoniae in bronchoalveolar lavage fluid from rats treated with plasma-derived antithrombin (BALF-AT) was reduced (closed symbols), compared with the outgrowth in BALF-none samples (open symbols). * P < 0.0001 vs. BALF-AT. (b) In vitro added plasma-derived AT did not affect the number of colony-forming units (CFU; for clarity only the highest concentrations are shown: 1.1 mg/mL, open symbols; 4.4 mg/mL, closed symbols). (c) Sodium polyanetholsulphonate (SPS) blocked the inhibitory effect of BALF-AT on outgrowth of S. pneumoniae (BALF-AT without SPS, closed symbols; BALF-AT with SPS, open symbols). Data represent mean ± standard deviation. * P < 0.0001 vs. BALF-AT without SPS.
