Calculated EC50values for each horse before and after treatment with 10-5 mol/l beclomethasone dipropionate. Means of the calculated EC50 values of the two contraction series (LTC4 with and without BDP) differed significantly from each other (p = 0.002). The number indicates the negative power of 10 (mol/l) as the expression of the LTC4 concentration needed to reach 50% of lumen reduction.
