For the 16 infected subjects who had all three challenges, the median (range) PC15FEV1 for the histamine challenges was 36 (0.89-64), 62 (1.5-64) and 34 (0.94-64) mg.ml-1, respectively, and 32 mg.ml-1 for each bradykinin challenge (range: 0.015-32, 0.088-32 and 0.033-32). There were no significant differences between study days for PC15FEV1 histamine or bradykinin for the whole group, the infected subjects, those with clinical colds or for those infected with either RV subtype. There was no significant change in mean daily PEF after viral infection. We conclude that airways reactivity to histamine and bradykinin is unchanged after experimental RV infection in normal volunteers. ER -
