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 Skyrme model provides a novel unified approach to nuclear physics. In this approach, single baryon, baryonic matter and medium-modified hadron properties are treated on the same footing. Intrinsic density dependence(IDD) reflecting the change of vacuum by compressed baryonic matter figures naturally in the approach. In this article, we review the recent progress on accessing dense nuclear matter by putting baryons treated as solitons, namely, skyrmions, on crystal lattice with accents on the implications in compact stars.

By incorporating hidden scale symmetry and hidden local symmetry in the nuclear effective field theory,combined with the double soft-pion theorem, we predict that the Gamow-Teller operator coming from the space component of the axial current should remain unaffected by the QCD vacuum change caused by the baryonic density,whereas the first forbidden beta transition operator coming from the time component should be strongly *** the latter has been confirmed for some time, the former was given support by a powerful recent ab initio quantum Monte Carlo calculation for light nuclei, which also confirmed the old？chiral filter hypothesis.＂ Formulated in terms of the Fermi-liquid fixed point structure of strong-coupled nuclear interactions, we offer an extremely simple resolution to the long-standing puzzle of the＂quenched g A,＂ gAeff ≈1 [1], found in nuclear Gamow-Teller beta transitions, giant Gamow-Teller resonances, and double beta decays.
