摘要: 目的 初步探讨氧化苦参碱(OMT)对哮喘小鼠的保护作用。方法 用Al(OH)3和卵清白蛋白诱发BALB/c小鼠过敏性哮喘,每日观察小鼠一般情况和体质量变化。哮喘模型建立后,予OMT或地塞米松进行治疗,分别在治疗后5 d、15 d处死部分小鼠,留存肺组织和支气管肺泡灌洗液进行检测。将留存的肺组织行HE染色观察其病理变化,BALF预处理后瑞氏染色行细胞总数和嗜酸性粒细胞计数。结果 OMT介入可改善哮喘小鼠体质量降低,在治疗后5 d和15 d时,各治疗组肺组织亦出现与哮喘模型组相似的病理变化,但炎性细胞或嗜酸细胞浸润不同程度减少。OMT的各治疗组与哮喘模型组比较,BALF中的细胞总数和嗜酸性粒细胞计数均降低(P<0.05或P<0.01)。结论 氧化苦参碱对哮喘小鼠具有治疗作用。

Abstract: Objective To study the protective effect of Oxymatrine (OMT) on asthma mice. Methods The asthmatic BALB/c mice were induced by ovalbumin (OVA) and aluminium hydroxide.The general situations and weights of mice were observed every day. Then these mice were treated by using OMT and/or dexamethasone and were sacrificed at 5 or 15 days after treatment. The bronchoalveolar lavage fluid (BALF) and lung tissue of mice were obtained. Their pathological reaction was observed through HE stain. The total number of cells and eosinophilscells in BALF were counted. Result OMT can improve the weights of asthma mice. On day 5 and 15, the pathological reactions of the lung tissue in each treatment groups were the same with that of the asthma group, but the number of inflammatory cells in lung tissue was much less than that of the asthma group. The total number of cells and eosinophils cells in BALF were reduced compared with the asthma group (P<0.05 or P<0.01). Conclusion OMT has protective effect on the asthma mice.
