In Vitro Inhibition of Neutrophil Elastase Activity by Inhaled Anti-Pseudomonas Antibiotics Used in Cystic Fibrosis Patients

Figure 1

Effects of colistin (a) and tobramycin (b) on neutrophil elastase measurement (absorption) are given for different concentrations of colistin and tobramycin (1, 10, 100, 1000 $\mu$M) either in presence (filled symbols, continuous lines) or in absence (blank symbols, dashed lines) of albumin. Data are presented as means of $n=3$. *P  <  .05; **P <  .01 compared to controls.
