【Abstract】 Objective To observe the effects of Zibaishizhen Granules (ZG) against allergic reactions. Methods The 48-hour rat-homologous passive cutaneous anaphylaxis (PCA) was used to observe the effects of ZG on type Ⅰ allergic reaction; the reversed cutaneous anaphylaxis (RCA) was used to observe the effects of ZG on type Ⅱ allergic reaction; Arthus reaction was used to observe the effects of ZG on type Ⅲ allergic reaction; 2,4-Dinitrochlorobenzene (DNCB) method was used to observe the effects of ZG on type Ⅳ allergic reaction; and the effects of ZG on degranulation of mastocytes mediated by rat homocytotropic antibodies, and on the production of hemolysin were also observed in the experiment. Results Intragastric administration of ZG at a dose of 2.5 g/kg could markedly inhibit rat PCA (P<0 5); the same administration of ZG at the doses of 1.5 g/kg and 2.5 g/kg could inhibit degranulation of mastocytes mediated by rat homocytotropic antibodies, wit the inhibitory rates as 37.8% and 41.5%, respectively. When being administered at the doses of 0 5 g/kg, 1.5 g/kg and 2.5 g/kg, ZG could inhibit rat RCA, with the inhibitory rates as 65 0%, 68 15 and 70.2%, respectively. ZG could also markedly inhibit rat Arthus reaction and mouse delayed type hypersensitivity induced by DNCB, and decrease mouse thymus index and spleen index. Conclusion ZG can exert significant inhibitory effects on the allergic reactions of type Ⅰ to type Ⅳ, and on degranulation of mastocytes mediated by homocytotropic antibodies.更多还原
