Fig. 1From: Cyclooxygenase-2-Dependent Bronchoconstriction in Perfused Rat Lungs Exposed to Endotoxin Time course of LPS-induced bronchoconstriction ( n = 6) and its prevention by pretreatment with the unspecific cyclooxygenase inhibitor acetyl salicylic acid (ASA, 275 µ M; n = 4) or the specific cyclooxygenase-2 inhibitor CGP28238 (C38, 1 µ M; n = 3) 10 min before injection of LPS (50 µ g/ml) Data are expressed as means ± SEM. R/Ro′, resistance normalized to time point 0.Back to article page
