Objective： Cheongseoikki-tang （CIT, Korean）, also called Qingshu Yiqi decoction（清署益气汤）and Seisho-ekki-to （Japanese）, is well known as an effective traditional combination of herbs for treating cardiovascular diseases. This study was to research its effects on bone marrow-derived mast cell （BMMC）-mediated allergy and inflammation mechanisms. Methods： In this study, the biological effect of Cheongseoikki-tang ethanol extract （CITE） was evaluated, focusing on its effects on the production of allergic mediators by phorbol 12-myfistate 13-acetate （PMA） plus calcium ionophore A23187 （A23187）-stimulated BMMCs. These allergic mediators included intedeukin-6 （IL-6）, prostaglandin D2 （PGD2）, leukotfiene （34 （LTC4）, and β-hexosaminidase （13-hex）. Results： Our data revealed that CITE inhibited the production of IL-6, PGD2,/TC4, and 15-hex induced by PMA plus A23187 （P〈0.05）. Conclusion： These findings indicate that CITE has the potential for use in the treatment of allergy.

The rapid advance of optical communication technology requires improvements in data transmission capacity and efficiency. Conventional methods of increasing the transmission capacity such as polarization,wavelength, and spatial mode division multiplexing have shown significant promise, while spatial mode division multiplexing(SDM) offers a new approach through the use of orthogonal spatial modes as distinct communication channels.
