Representative hematoxylin and eosin-stained lung sections collected after assessment of pulmonary mechanics from mice. (B) and (C) is OVA sensitized with single-dose OVA challenge, measured invasively (B) or by Penh measurements (C). (D), (E) and (F) are OVA sensitized with three-dose OVA challenge, measured invasively (D) or by Penh measurements (E, F).Back to article page
