摘要
目的 初步探讨喘宁软胶囊的平喘作用机制。方法 采用整体试验观察致敏小鼠抗原攻击后肺灌洗液和周围血中的嗜酸性粒细胞聚集反应 ,采用离体试验观察致敏大鼠抗原攻击后腹腔肥大细胞脱颗粒反应。结果 喘宁软胶囊 2 ,4 ,8g/ kg和对照药地塞米松 2 m g/ kg ig给药显著减少肺灌洗液和周围血中嗜酸性粒细胞的浸润。喘宁软胶囊 33.3,6 6 .7mg/ L 和对照药酮替芬 0 .333m g/ L 明显抑制致敏大鼠腹腔肥大细胞脱颗粒反应。
Object To explore the antiasthma mechanism of CHUANNING SOFT CAPSULE (CNSC). Methods The eosinophils accumulation in bronchoalveolar lavage fluid (BALF) and peripheral blood in the ovalbumin sensitized mice after challenged with antigen in vivo was examined and the granulation of the peritoneal mast cells in the ovalbumin sensitized rats after challenge of antigen in vitro was observed. Results CNSC 2, 4, 8 g/kg (ig) and dexamethasone 2 mg/kg (ig) significantly reduced the eosinophils infiltration in BALF and peripheral blood. CNSC 33.3, 66.7 mg/L and ketotifen 0.333 mg/L significantly inhibited granulation of mast cells. Conclusion The antiasthma mechanism of CNSC probably correlates with suppressing eosinophils infiltration in lung and stabilizing mast cell membranes.
