研究镇咳药物的实验方法很多,但适用于筛选镇咳药物的方法不多。我国医药科学工作者在研究防治慢性气管炎药物工作中,采用一些简便方,筛选镇咳中草药。在这些方法中,以氢氧化铵气雾法应用较为普遍。此法具有简便易行、效率高、容易掌握等优点。我们用此法进行实验时,发现氢氧化铵气雾对实验者呼吸道亦有刺激作用。为解决这一问题,我们改进了实验装置,将氢氧化铵喷雾装置改为氨气吸入装置。
There are many experimental methods for studying antitussive drugs, but there are not many methods for screening antitussives. Chinese medical scientists in the prevention and treatment of chronic bronchitis drug work, the use of some simple side, screening antitussive Chinese herbal medicine. Among these methods, the use of ammonium hydroxide gas mist method is more common. This method is simple, efficient, easy to master and so on. When we used this method to conduct experiments, we found that ammonium hydroxide aerosol also stimulated the respiratory tract of the experimenter. To solve this problem, we modified the experimental setup to change the ammonium hydroxide spray unit to an ammonia vacuum unit.
