In the healthy controls, no consistent change in BAL cell profile and mediators occurred after methacholine provocation. We conclude that inhaled methacholine stimulates LTB4 and PGD2 release in asthmatics, but not in healthy controls, without affecting the number of inflammatory cells in BAL fluid.
