The aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor that mediates the biological action of many aromatic environmental pollutants. In this study, we investigated the activation of the AhR by some vegetable constituents using the AhR-based bioassay for dioxins, i.e., the chemical activated luciferase gene expression (CALUX) assay. Ninety-five vegetable constituents, in...

The anti-allergic activity of the 50% methanol extract of Citrus unshiu powder (MEC) was examined. Fifty percent methanol extract of MEC powder showed potent inhibitory activity against histamine release from basophils of patients suffering from seasonal allergic rhinitis to ceder pollen. To examine this anti-allergic mechanism in detail, we next used rat basophlilic leukemia RBL-2H3 cells. MEC...
