Ratio of CysLTs to PGE2 in induced sputum following exercise challenge. The levels of CysLTs and PGE2 were measured in induced sputum in a group of asthmatics with EIB (A) and in a nonasthmatic control group (B) at baseline and after exercise challenge. The results demonstrate opposing effects of an increase in the CysLT/PGE2 ratio after challenge in the asthma group, whereas the ratio decreased after challenge in the control group.
