Objective：By observing Maxingshigan Decoction（MXSGD） on immune organ weight index of mice which were infected by A-type influenza virus and levels of IL-2、TNF-β,to explore immune protection of mice which were infected by A-type influenza virus. Methods： Use nasal inoculation to establish mouse pulmonary infection model animals by A-type influenza virus. Set up MXSGD group,ribavirin group,Anti-virus particle group,model control group and normal control group. After gavaging drug or normal saline,detection of weight in mice,lung index,splee...
