人参“止咳化痰”药理实验研究

目的：研究人参的止咳、化痰作用。方法：采用浓氨水、SO2引咳法观察其止咳作用；采用小鼠酚红排泌法、大鼠毛玻璃管排痰法观察其化痰作用。结果：人参能延长氨水和SO2引咳咳漱潜伏期、减少咳漱次数、促进小鼠气管酚红排泌量及大鼠排痰量。结论：人参具有止咳、化痰作用；借助古代方剂文献的系统筛选，提炼中药潜在功能，再经实验研究加以确认，是挖掘中药新功能切实可行的方法和途径。

Pharmacological Study on the Role of Ginseng in Dissipating Phlegm and Relieving Coughing

This work studied the role of Ginseng in dissipating phlegm and relieving coughing. High-concentration ammonia and SO2 were used to induce coughing to observe the function of Ginseng in relieving coughing, and mouse phenol red excretion and rat glass wool were used to observe the role of Ginseng in dissipating phlegm. The results showed that Ginseng prolonged the incubation period of coughing induced by ammonia and SO2,reduced the coughing times, and stimulated the excretion of mice phenol red and rat phlegm. Therefore, Ginseng plays a certain role in dissipating phlegm and relieving coughing. This provides a feasible method to explore the new functions of Chinese medicine. That is, based on the systematic selection of ancient medicinal records, to discover the potential functions of Chinese medicine and then to further confirm their functions by experimental research.
