Figure 2From: Inhibition of LPS-induced airway neutrophilic inflammation in healthy volunteers with an oral CXCR2 antagonistEffect of AZD8309 on cell counts in sputum post LPS challenge. Total cell counts (top left plot) were performed by trypan blue exclusion with a hemocytometer. Differential cell counts for neutrophils (top right plot) and macrophages (bottom centre plot) were performed with cytospin preparations. Bars show the mean values of 15–16 patients. Open bars represent placebo and solid bars AZD8309. Results are expressed as geometric mean. CVs are shown in Table 2. Statistics by ANOVA, ** = P < 0.001 and * = P < 0.05.Back to article page
