目的:研究穴位贴敷“咳喘宁”贴膏对实验动物的止咳、祛痰、平喘作用。方法:采用“氨水引咳法”、“气管酚红排泌法”观察穴位贴敷“咳喘宁”贴膏对小鼠的镇咳、祛痰作用;采用“卵白蛋白诱喘法”观察“咳喘宁”贴膏对哮喘模型大鼠的平喘作用。结果:穴位贴敷“咳喘宁”贴膏能明显延长咳嗽、哮喘潜伏期,增加小鼠支气管酚红排泌量,减少咳嗽次数。结论:穴位贴敷“咳喘宁”贴膏具有明显的止咳、祛痰、平喘作用。
Objective: To study the antitussive, expectorant and antiasthmatic effects of acupoint application of “kechuanning” patch on experimental animals. Methods: Using “ammonia water coughing method” and “tracheal phenol red excretion method” to observe the antitussive and expectorant effects of acupoint application of “Kechuanning” patch on mice; “Ovalbumin induced asthma” was used to observe “ Effect of ”Kechuanning“ plaster on asthma model rats. Results: Acupoint application of ”kechuanning“ patch can significantly prolong cough, asthma incubation period, increase the amount of phenol red excretion in mice, and reduce the number of cough. Conclusion: Acupoint application of ”kechuanning" plaster has obvious antitussive, expectorant and antiasthmatic effects.
