Abstract:
Objective To explore the antitussive action site and potential mechanism of Shegan Zhike Capsule.Methods The mouse cough model induced by concentrated ammonia was used to observe the dose effect relationship of the antitussive effect of Shegan Zhike capsule.The central antitussive effect of Shegan Zhike capsule was observed by using the cough model induced by electrical stimulation of superior laryngeal nerve in guinea pigs.The peripheral antitussive effect of Shegan Zhike capsule was observed by using the cough model of capsaicin desensitized guinea pigs induced by mechanical stimulation.The model of chronic bronchitis in guinea pigs was established by smoking,and the effects of Shegan Zhike Capsule on vasoactive amines histamine(HA)and 5-hydroxytryptamine(5-HT)were observed.Results Shegan Zhike capsule could significantly reduce the number of coughs in mice at the doses of 43.00,86.00 and 172.00 mg extract·kg-1(P<0.05 or P<0.01).The low-dose group,the middle-dose group,and the high-dose group of Shegan Zhike Capsule did not significantly inhibit the cough inducing effect of electrical stimulation of guinea pig superior laryngeal nerve at 30 min and 60 min after administration.Shegan Zhike capsule could significantly inhibit the cough of capsaicin desensitized guinea pigs caused by mechanical stimulation in the low dose group at 60 min,the medium dose group at 30 min and the high dose group at 30 min and 60 min(P<0.05).Compared with the model control group,the content of HA in serum of guinea pigs in low,medium and high dose groups of Shegan Zhike capsule decreased significantly(P<0.05 or P<0.01).The content of serum 5-HT in the high dose group decreased significantly(P<0.05).Conclusion The antitussive effect of Shegan Zhike Capsule was not in the center,and its peripheral antitussive effect was related to the inhibition of RARs receptors,and vasoactive amines such as HA and 5-HT were also involved.
