Methods: 18 male SD rats were selected and divided into control group, model group and drug administration group. In the model group, mast cell degranulation was induced by MCDP stimulation. The treatment group was treated with tripterine after MCDP stimulation. Serum IgE was detected by ELISA. The mRNA expression levels of IL-1β and IL-10 were analyzed by Q-PCR. Results: ELISA results showed that compared with the control group, the serum IgE content in the model group was significantly increased, while the serum IgE content in the drug group was significantly lower than that in the model group. Q-PCR results showed that the gene expression levels of IL-1β and IL-10 in the model group were (3.83 ± 0.92) and (3.98 ± 0.46), respectively, which were significantly increased compared with the control group. The gene expression in drug group was significantly lower than that in model group (P β and IL-10 mRNA, suggesting that tripterine can inhibit mast cells.展开更多
