4 results about "Asthma model" patented technology

This invention provides a traditional Chinese medicine composition for treating or improving asthma, relating to the field of traditional Chinese medicine pharmaceutical technology. The composition comprises the following raw materials: Inula japonica, Bambusa textilis, Lysimachia christinae, Rutaecarpa, Ligusticum striatum, Pyrrosia lingua, Chaenomeles speciosa, Dioscorea hypoglauca, Atractylodes lancea, walnut kernel, maltose, Citronella arvense, and Glycyrrhiza uralensis. In this invention, each ingredient in the composition fulfills its specific function, addressing both the symptoms of asthma (phlegm and qi stagnation, and upward flow of lung qi) and the underlying causes (spleen strengthening, kidney tonification, and liver soothing). This achieves the combined effects of dispelling wind and clearing the lungs, resolving phlegm and descending rebellious qi, strengthening the spleen and resolving dampness, warming the kidneys and promoting qi circulation, and regulating liver qi. It treats both the symptoms and the root cause. This invention's composition effectively inhibits airway inflammation in asthma model mice, improves clinical symptoms, and demonstrates significant therapeutic effects. The composition exhibits a high overall effective rate in treating asthma, with particular advantages in alleviating clinical symptoms and improving lung function in asthma patients.

This invention provides the use of a trisaccharide compound with a core structure of Glc(1→4)IdoA(1→4)GlcNS in the preparation of a drug for treating or preventing asthma. This compound can reduce lung inflammation in asthma model mice, reduce mucus production in the trachea, and effectively improve ventilation.

This invention relates to the field of traditional Chinese medicine (TCM) technology, and particularly to the application of TCM compositions in the preparation of drugs for the prevention and treatment of asthma. The TCM composition includes Astragalus membranaceus, Eupolyphaga sinensis, Morus alba root bark, Fritillaria cirrhosa, Perilla frutescens seed, Lepidium apetalum seed, Prunus armeniaca seed, Pheretima aspergillum, Ephedra sinica, and Clematis chinensis. Experiments show that the TCM composition provided by this invention can effectively improve airway hyperresponsiveness, reduce lung resistance, and enhance dynamic lung compliance in asthma model animals. Simultaneously, it can significantly reduce the content of pro-inflammatory factors IL-4 and IL-13 in the bronchoalveolar lavage fluid of asthma models, alleviate airway inflammation, and relieve asthma pathological symptoms. It can stably exert its effect in preventing and treating asthma, and its efficacy is stable and its safety is good. It can be further developed into a drug for the prevention and treatment of asthma and has good clinical application prospects.
