Abstract

The invention discloses application of pulsatilla saponin B4 in preparing a medicine for treating / preventing influenza virus-induced viral pneumonia of mammals including human beings. The pulsatilla saponin B4 has a protection function on FM1 induced viral pneumonia, and the protection mechanism may be related to reduction of expression of inflammatory factors and inhibiting expression of proteinsTLR4, MD2 and MyD88.

Description

technical field [0001] The invention relates to the technical field of medicine. More specifically, the present invention relates to the use of Pulsatilla saponin B4 in the preparation of drugs for the treatment / prevention of viral pneumonia. Background technique [0002] Influenza A (H1N1) first broke out in Mexico in April 2009, and then spread globally. China classifies Influenza A virus H1N1 as a Class B infectious disease and adopts preventive and control measures for Class A infectious diseases. Influenza viruses are highly variable and contagious, and immunocompromised people are vulnerable. When the influenza virus proliferates in the lung bronchial epithelial cells and lung tissue, it can cause severe pathological tissue damage, such as pulmonary edema, inflammatory exudation, congestion, etc., leading to bronchitis and interstitial pneumonia. Severe infection, Respiratory failure, multiple organ dysfunction, etc., even lead to death, seriously affecting the qual...
