Text: Comparing median challenge-induced relative changes in cells and mediators, neither histamine nor AMP challenge altered the induced sputum neutrophil counts (histamine, 2. 7 % ; AMP, 2. 95 % ; placebo, -2 % ; P >. 07 for all), interleukin 8 levels (histamine, 2. 4 ng/mL ; AMP, -3. 8 ng/mL ; placebo, -0. 2 ng/mL ; P >. 06), leukotriene B4 levels (histamine, -4. 8 pg/mL ; AMP, 3 pg/mL ; placebo, 6 pg/mL ; P >. 08), or myeloperoxidase levels (histamine, 0. 16 microg/mL ; AMP, 0 microg/mL ; placebo, -0. 03 microg/mL ; P >. 07).
