本文采用蝉蜕的水提液进行离体大鼠肠管解痉实验。结果表明蝉蜕能缓解乙酰胆碱所致的肠痉挛,并进行小鼠镇咳试验。结果表明蝉蜕水提液(100％)与磷酸可待因(0.2％)溶液对氢氧化铵溶液(27—29％)引起咳嗽潜伏期和咳嗽次数相差不显著(P>0.05)。说明蝉蜕有一定的镇咳作用。笔者认为蝉蜕治疗痉挛性咳嗽可能与蝉蜕的解痉和镇咳作用有关。
In this article, the water extracts of lanthanum were used to perform the experiment of intestine spasmolysis in vitro. The results showed that wolfberry can relieve intestinal fistula caused by acetylcholine, and the mouse antitussive test. The results showed that the difference between the cough latency and the number of coughs caused by the ammonium hydroxide solution (27-29%) was not significant (P>0.05) in the aqueous extract (100%) and the codeine phosphate (0.2%) solution. It shows that there is a certain antitussive effect. The author believes that treatment of spastic cough may be related to sputum spasmolysis and antitussive effect.
