Experimental scheme diagram. The LPS was gradually dripped into the airway of male rats of SPF grade (4–6 weeks old) at week 0 and week 2. These rats were not exposed to smoke on the day of the surgery but were exposed to smoke for the remaining 12 weeks. From week 12 onward, administration was given continuously for two weeks and the rats were sacrificed and the samples were obtained at week 14.
