(R)-Albuterol decreases pulmonary inflammation after OVA sensitization and aerosol challenge. On the first day of OVA challenge (day 14, see Methods) a miniosmotic pump (Alzet) containing (R)- or (S)- albuterol was inserted subcutaneously (200 μg/100 μl) and delivered a constant dose of 1 mg/kg/day (25 μl/day). A) PBS+pump, B) OVA+ pump, C) PBS+(R), D) OVA+(R), E) PBS+(S) and F) OVA+ (S). These pictures are representative of two mice examined in each group. Arrows show inflammatory cells. Magnification 10×.
