The actions of 2-APB and flufenamic acid (FFA) on 5-hydroxytryptamine (5-HT)-elicited pulmonary arterial contraction are reduced by antenatal maternal LTH. Bars indicate mean ± SEM of %T5-HT Control for the noted condition in pulmonary arterial rings from normoxic (open) or LTH (solid) fetal sheep. **P < .01 and ***P < .001 denote significant difference from control based on a 2-way ANOVA and a Bonferroni post hoc analysis. LTH indicates long-term hypoxia; SEM, standard error of the mean; ANOVA, analysis of variance.
