The effects of chrysin on the production of BALF cytokines. BALF was collected from different groups of mouse lung. The concentrations of TNF-α (left), IL-1β (middle), and IL-8 (right) in BALF were analyzed by ELISA. Values are expressed as mean ± SD. A. Control, no chrysin pretreatment and no exposure to cigarette smoke; B. CS, no chrysin pretreatment and exposure to cigarette smoke; C. CS+Chrysin(L), mice pretreated with 10 mg/kg chrysin and exposed to cigarette smoke; D. CS+Chrysin(H), mice pretreated with 20 mg/kg chrysin and exposed to cigarette smoke. *P<0.05 with respect to the control group, #P<0.05 with respect to the cigarette smoke-exposed group.
