Abstract：Objective To establish an acute lung injury model by cotton smoke inhalation in rats.Methods Twenty-four male SD rats were randomly allocated into control group, after smoke inhalation 3h, 6h and 24h group.The changes in blood gas analysis, inflammatory mediators such as interleukin 8 (IL-8) were monitored in every group.Histopathology of lung in rats were observed. Results Compared with control group.PaO2 and PaCO2 were significantly decreased in every smoke inhalation group(P<0.05).The increased of inflammatory mediators clew that lung injury were occurred after smoke inhalation in rats.Obvious edema, alveolar atrophy and inflammatory infiltra-tion were found in smoke inhalation rats.Conclusion An acute lung injury model by cotton smoke inhalation in rats has been successfully established.
