OBJECTIVE To investiate the bacteriostasis and anti-inflammation function of the Compound Lung Protecting granules. METHODS Use the minimum inhibitory concentration(MIC) values in vitro to observe the bacteriostasis effect. The anti-inflammation function of the Compound Lung Protecting granules was analyzed by its inhibition to the swelling of mouse pinna induced by dimethylbenzene, carrageenan induced rats' paw edema, and by its inhibition to the chronic bronchitis of mouse pinna induced by 2% sulfur dioxi...
