1 In order to investigate the role of interleukin-5 (IL-5) in airway hyperreactivity and eosinophilia, we observed the effect of inhaled recombinant human IL-5 on airway responsiveness to methacholine and cell populations in induced sputum in eight patients with allergic bronchial asthma using a placebo-controlled study design. Methacholine Chloride interleukin 5 Homo sapiens
2 In contrast, after IL-5 inhalation, methacholine PC20 fell from baseline (0.90 +/- 166 mg/ml) to 0.32 +/- 1.63 mg/ml (p < 0.01) at 24 h, and to 0.55 +/- 1.49 mg/ml (p < 0.05) at 48 h. Accompanying this increased airway sensitivity was a significant eosinophilia and elevated concentrations of ECP in induced sputum. Methacholine Chloride interleukin 5 Homo sapiens
