  1. HLA-DR expression on peripheral blood monocytes as well as on AMs was significantly reduced after surgery. In group 2 a strong reduction without statistical significance was seen. Data are given as medians and IQR in brackets. The Wilcoxon test was used to calculate significant difference for the depending variables; astatistically significant difference. HLA-DR, human leukocyte antigen-DR; AM, alveolar macrophage.
