Inhibitory Effect of Danggui Decoction on Passive Cutaneous Anaphylaxis in Mice / 广州中医药大学学报

ABSTRACT

【Objective】To explore the mechanism of Danggui Decoction (DD) in counteracting allergic reaction bymeans of passive cutaneous anaphylaxis (PGA) test.【Methods】Among fifty NEH mice, ten were used to prepareantiserum and the rest forty were randomized into 4 groups normal control group (A), clarityne group (B), low-doseDD group (C) and high-dose DD group (D) . PGA was induced by intraperitoneal injection of antiserum in the fourgroups and the mice were treated with gastric infusion simultaneously. After the last feeding, antigen attack wasconducted. Inhibitory rate of PCA in four groups were measured by colorimetric analysis after treatment. 【Results】High-and low-dose DD and clarityne could inhibit PCA in mice (P0.05).【Conclusion】The anti-allergic effect of DD may be associated with the inhibition of type Ⅰ allergic reaction.
