The aim of the study was to investigate the anti-asthmatic effects of oxymatrine(OXY) and the possible underlying mechanisms.The mouse asthma model was established by ovalbumin(OVA) intraperitoneal injection.A total of fifty mice were randomly assigned to five groups:control,OVA,OVA + dexamethasone(Dex,2 mg·kg-1),and OVA + OXY(40 mg·kg-1),and OVA + OXY(80 mg·kg-1),respectively.Histological studies were conducted by the hematoxylin and eosin(HE) staining,the levels of interleukin-4(IL-4),interleukin-5(IL-5),interleukin-13,and Ig E were evaluated by enzyme-linked immunosorbent assay(ELISA),and the protein level of CD40 was analyzed by Western blotting.OXY inhibited OVA-induced increases in eosinophil count;the levels of IL-4,IL-5,Ig E,and IL-13 were recovered.It also substantially inhibited OVA-induced eosinophilia in lung tissues and the expression of CD40 protein.These findings suggest that OXY may effectively ameliorate the progression of asthma and could be explored as a possible therapy for patients with allergic asthma.

Mouse asthma model was established by ovalbumin (OVA) intraperitoneal injection. A total of fifty mice were randomly assigned to five groups: control, OVA, OVA + dexamethasone (Dex, 2 mg · kg -1), OVA + OXY (40 mg · kg -1), and OVA + OXY by the hematoxylin and eosin (HE) staining, the levels of interleukin-4, interleukin-5, interleukin-13, and IgE were evaluated by enzyme-linked immunosorbent assay and the protein level of CD40 was analyzed by Western blotting.
