Objective: To investigate difference of antitussive activity and treatment of pneumonia in mice between Xiao'er Baibu Zhike Tangjiang with raw or processed products of Stemonae Radix. Method: Cough model of guinea pigs induced by citric acid was established to investigate antitussive difference between raw products compound and processed products compound with different doses.Lipopolysaccharide was adopted to stimulate mice pneumonia model and syncytial virus mouse pneumonia model
raw products compound and processed products compound were orally asministrated
concentration of tumor necrosis factor-α (TNF-α)
interleukin-10 (IL-10)
γ-interferon (IFN-γ) and IL-4 in rats bronchoalveolar lavage fluid were detected
lung tissues were sliced. Result: Compared with the same dose of raw products compound
middle and high dose of processed products compound showed distinctly stronger antitussive activity;compared with the high dose of raw products compound
high dose of processed products compound showed lower inflammatory cell infiltration and more regressive ratio of IFN-γ/IL-4. Conclusion: In order to play a better therapeutic effect
honey-processed Stemonae Radix should be used to prepare Xiao'er Baibu Zhike Tangjiang.
