Brief Summary:
This study is looking for allergic asthmatics. Lung and allergy testing will be done to verify. If qualified, blood will be drawn for laboratory studies.

Condition or disease
Allergy Asthma

Detailed Description:
Non-smoking allergic asthmatics will be verified using pulmonary function, skin prick testing, exhaled nitric oxide and serum IgE. If qualified, blood will be drawn, treated with study medication and then stimulated with the allergen to which the subject is allergic. Mediators including Histamine, IL-13, IL-4, and leukotrienes will be measured.
