摘要: There is some evidence that nitric oxide synthase (NOS) induced in the lungs of patients with allergic asthma, but mechanism this not understood. The aim present study was to investigate whether levels NOS rat lung could be altered by exposure animals aerosols allergen (ovalbumin). Brown-Norway rats were actively sensitized ovalbumin, raising a mixed IgE/IgG antibody response. total and calcium-independent tissue homogenates elevated at 6 h 24 after unsensitized rats. induction due contaminating lipopolysaccharide challenge solution. allergen-induced increase inhibited pretreatment corticosteroid betamethasone (3 mg kg-1 i.p., 1 prior allergen). These results show induces rats, process an anti-inflammatory corticosteroid.
