RESUMEN
Objective:To evaluate the cough-settling, phlegm-dispelling and panting-calming actions of Ginkgo Distillate. Methods: The cough-settling and phlegm-dispelling effects were observed on the ammonia water-induced cough model of mice and phenol red expectoration method. The panting-calming effect was observed by wheezing and panting incubation period and relaxation test of isolated tracheal smooth muscle. Results: Ginkgo Distillate could inhibit mouse cough induced by ammonia water, promote mouse tracheal expectoration induced by phenol red, remit the wheezing and panting induced by histamine phosphate, prolong the wheezing and panting incubation period. It also possessed the inhibition on guinea pig tracheal contraction induced by histamine phosphate. Conclusions: Ginkgo Distillate has the cough-settling, phlegm-dispelling and panting-calming actions.
RESUMEN
Objective:To prove the pharmacological action of Qingfei Capsules.Methods: Some tests such as suppressing cough, dispelling phlegm, calming panting, anti-inflammation, anti-virus, its effects on the nonspecific immunity and cellular immunity of mice were carried out. Results: Qingfei Capsules could prolong the incubation period of cough, wheezing and panting, possess the actions of dispelling phlegm and inhibiting inflammation, raise the nonspecific immunity of body, promote humoral immunity, and raise the cellular immune function.Conclusions: These results provide a basis for clinical application of Qingfei Capsules.
