(A) Ear-thickness measurements in Balb/c mice with chronic oxazolone-induced dermatitis. Mice were challenged up to day 30 and then allowed to convalesce. The arrow denotes the time of the last challenge. I, sensitization; II, acute swelling; III, chronic inflammation (plateau) (n=5). (B) Scheme of protocol and measurement of lung function in mice where OVA-induced airway reactivity was initiated 5 weeks following cessation of oxazolone challenges (n=5). (R = resistance and Cdyn = compliance). *, p=0.014; ***, p<0.0001.
