Abstract

The invention discloses application of a total flavonoids aglycon extract of baical skullcap root in the preparation of a medicament for preventing and treating pulmonary fibrosis. The invention adopts a technical scheme that: by internally instilling bleomycin AS (BLM A5) in the weasand, a mouse pulmonary fibrosis animal model is copied; the total flavonoids aglycon extract (the content of total flavonoids aglycon is more than or equal to 50 percent) of the baical skullcap root is selected as the treatment medicament for the first time; the interference effect of the total flavonoids aglycon extract of the baical skullcap root on biochemical indexes associated with the serum and the lung tissue of the pulmonary fibrosis animal model and the influence of the total flavonoids aglycon extract of the baical skullcap root on the pathomorphism of the lung tissue are observed to provide an experiment evidence for the treatment of pulmonary fibrosis diseases by the total flavonoids aglycon extract of the baical skullcap root. The medicament is a medicament prepared by combining a therapeutically effective amount of the total flavonoids aglycon extract of the baical skullcap root and a pharmaceutically acceptable vector.

Description

technical field [0001] The present invention relates to the application of an extract of the effective part of a traditional Chinese medicine in the preparation of a drug for preventing and treating pulmonary fibrosis, in particular to the application of the effective part of the traditional Chinese medicine Scutellaria baicalensis, the total flavonoid aglycone extract of Scutellaria baicalensis, in the preparation of a drug for preventing and treating pulmonary fibrosis , belonging to the field of medical technology. Background technique [0002] Pulmonary (interstitial) fibrosis (Pulmonary fibrosis, PF), also known as interstitial lung disease (Interstitiallung disease, ILD), is a common outcome of acute and chronic lung diseases caused by various causes. The etiology is complex, and it is now believed that it may be related to genetic susceptibility, viral infection, abnormal immune function, environmental pollution, drugs and chemicals, and radiation. About 50% of ILD i...
