on eosinophil survival primed bycultured epithelial cell supernatants obtained fromnasal mucosa andnasal polyps

Background - Supernatants fromepithelial cellcultures enhanceeosinophil survival invitro, thiseffect beingabrogated byprevious incubation ofeosinophils withglucocorticoster oids. This property hasresulted inthedevelopment ofaninvitro testtocomparethepotency ofthesedrugs. A comparative studywas performed withdexamethasone, methylprednisolone, deflazacort, and budesonide.
