Abstract
Objective:
To study the mechanism of Ma Xing Shi Gan decoction on the cytokines of Th1/Th2 in a murine model of asthma.
Methods:
The murine model of asthma was induced by OVA. Various doses of Ma Xing Shi Gan decoction were orally administered to the mice respectively. The spleen cells were cultured 3 days for measurement of IFN-gamma, IL4 and IL-5 by ELISA. After 2 days' culture, the spleen cells were treated with Trizol for extraction of total RNA. The gene expression of T-bet, GATA-3 and STAT-6 were analyzed by RT-PCR.
Results:
After the treatment with Ma Xing Shi Gan decoction, the production of IL-4 and IL-5 and the gene expression of GATA-3, STAT-6 obviously decreased.
Conclusion:
Ma Xing Shi Gan decoction may modulate Thl/Th2 balance by suppressing the gene expression of GATA-3 and STAT-6 in vivo.
