摘要：目的建立BALB/c小鼠阴虚型过敏性哮喘模型并进行评价。方法采用腹腔注射与皮下注射卵清白蛋白(OVA)致敏、雾化吸入OVA激发的方法复制过敏性哮喘BALB/c小鼠模型,激发后期合并灌胃甲状腺素复制阴虚型过敏性哮喘模型。在监测饮食、饮水及体质量的基础上,对支气管激发过程中哮喘行为学、肺功能及肺组织病理学等哮喘相关指标进行观测,同时对cAMP、cGMP及肺液清除功能等阴虚证相关指标进行考察。结果阴虚哮喘模型组小鼠出现明显的哮喘症状,哮喘行为学综合评分明显升高,吸气峰流量、呼气峰流量、潮气量明显下降,呼吸频率增加,肺组织病理学可见明显的炎症反应;同时,阴虚哮喘模型组小鼠进食与饮水量明显增加,而体质量增长缓慢,肺组织湿重/干重比值下降,血清cAMP及cAMP/cGMP升高,cGMP下降,显示小鼠处于阴虚而阳相对亢盛的状态。结论在OVA致敏、激发的基础上给予甲状腺素,可成功复制BALB/c小鼠阴虚型过敏性哮喘模型。
Objective To establish and evaluate a BALB/c mouse model of anaphylactic asthma with yin-deficiency syndrome. Methods Ovalbumin（OVA） was injected to sensitize and was inhaled to stimulate to replicate the BALB/c mouse model of anaphylactic asthma. Thyroxin was used for gavage during late stimulation to replicate the BALB/c mouse model of asthma with yin-deficiency syndrome. On the basis of monitoring food and water intake and body weight, asthma related indexes, such as asthmatic behaviors, respiratory function, lung histopathology, were detected, and yin-deficiency syndrome related indexes, such as c AMP and cGMP, and pulmonary fluid clearance were examined. Results The BALB/c mouse model of asthma with yin-deficiency syndrome showed obvious asthma symptoms; comprehensive scores of asthmatic behaviors increased significantly; inhaling peak flow, exsufflation peak flow, and tidal volume decreased significantly; lung tissue histopathology showed obvious inflammatory response. Meanwhile, food and water intake of BALB/c mouse model of asthma with yin-deficiency syndrome increased significantly; body weight increased slowly; wet/dry ratio of lung tissue decreased; cAMP and cAMP/cGMP increased, while cGMP decreased, which showed that the mice were in the condition of yin-deficiency and yang-excess. Conclusion Combining thyroxin at the basis of sensitivity induced by OVA is a good pattern to successfully replicate the BALB/c mouse model of anaphylactic asthma with yin-deficiency syndrome.
