Biochanin A, a Phytoestrogenic Isoflavone with Selective Inhibition of Phosphodiesterase 4, Suppresses Ovalbumin-Induced Airway Hyperresponsiveness

<table>Displacement of [<sup>3</sup>H]-rolipram by biochanin A (a) and rolipram (b) in high-affinity rolipram binding sites of guinea pig whole-brain particulates. Each value represents the mean ± SEM. The numbers of experiments for biochanin A and rolipram were 4 and 8, respectively.</table>
