Abstract

The invention relates to the technical field of application of artemisia scoparia extracts, and relates to application of an artemisia scoparia extract for preparing a medicine for treating pneumonia caused by streptococcus pneumonia or / and beta hemolytic streptococcus. The invention discloses the application of the artemisia scoparia extract for preparing the medicine for treating pneumonia caused by streptococcus pneumonia or / and beta hemolytic streptococcus for the first time. In-vitro antibacterial tests show that the artemisia scoparia extract has a function of remarkably inhibiting growth of streptococcus pneumonia and beta hemolytic streptococcus, anti-inflammatory tests show that the artemisia scoparia extract has anti-inflammatory activity, and meanwhile, the artemisia scoparia extract has a protection function on mouse lung injury models, so that the result shows that the artemisia scoparia extract has a treatment effect on pneumonia caused by streptococcus pneumonia or / and beta hemolytic streptococcus, and thus novel ways are provided for treatment on pneumonia caused by streptococcus pneumonia or / and beta hemolytic streptococcus.

Description

technical field [0001] The invention relates to the technical field of the application of Artemisia marinae extract, and relates to the application of Artemisia marinae extract as a drug for preparing and treating pneumonia caused by Streptococcus pneumoniae or / and B-hemolytic Streptococcus. Background technique [0002] Pneumonia refers to inflammation of the terminal airways, alveoli, and interstitium of the lung, which can be caused by pathogenic microorganisms, physical and chemical factors, immune damage, allergies, and drugs. According to anatomy, pneumonia can be divided into lobar pneumonia, lobular pneumonia and interstitial pneumonia; according to the etiology, it can be divided into bacterial pneumonia, pneumonia caused by atypical pathogens, viral pneumonia, fungal pneumonia, pneumonia caused by other pathogens, and pneumonia caused by other pathogens. Pneumonia caused by physical and chemical factors; divided into community-acquired pneumonia and hospital-acquir...
