The discovery of drugs on the treatment of rhinitis and allergic disease is a very important subject in human heath. The Shinbijen has been used for centruries as a traditional medicine in Korea and is known to have an anti-inflammatory effect. However, its specific mechanism of action is still unknown. In this report, we investigated the effect of hot water extract from Shinbijen on OVA-mediated allergic reaction and studied its possible mechanism of action using fluorescenc microscopy and RT-PCR analysis. Shinbijen inhibited OVA-induced rhinitis, total cells in BFA and lymphocyte related to inflammation in mice. Shinbijen decreased immuno response, which activated by IL-4, COX-2 and iNOS expression. in tissue. Shinbijen reduced inflammatory molecule release from mice lung tissue and CD4/CD8 cells activated by cardiac blood. Shinbijen decreased OVA-induced IL-4 and iNOS levels in pulmonary alveoli. Our findings provide evidence that Shinbijen inhibits OVA-induced allergic reactions, and also demonstrate the involvement of inflammation and allergic disease in these effects.
