ABSTRACT
Objective To investigate the effect of inhaled pravastatin on the acute inflammation of lung in smoked rats.Methods 32 male SD rats were randomly divided into four groups(n=8 per group),as the controls,cigarette-smoking exposure group,saline or pravastatin treatment groups.The rats in the control group were treated routinely,the other groups were exposed to cigarette smoking for one week.Rats in saline or pravastatin group were treated with saline or pravastatin inhalation respectively.During smoking exposure period rats were weighted before and after the treatment,executed at day eight,blood,bronchoalveolar lavage fluid(BALF),and lung tissue were collected.The morphological alternations of lung tissue were observed.Total cell numbers in BALF were counted.Enzyme-linked immunosorbent assay(ELISA) was used to detect the levels of serum IL-10 and IL-17 content.Results The increase of body weight of smoke-exposed rats were less than that of the controls.In smoking-exposed rats,acute inflammatory changes were remarkable in the lung.The total cell numbers in BALF and levels of IL-10 were increased significantly(P<0.05).These changes were mitigated in pravastatin treated rats and an IL-10/IL-17 rebalance was observed.Conclusion Inhalation of pravastatin sodium has a certain inhibitory effect on cigarette smoke-induced acute lung inflammation in rats.
