ABSTRACT
Objective To observe the pulmonary inflammation and oxidative stress in rats with cecal ligation and puncture sepsis. Methods The male rats in 8 weeks were randomly divided into control group, sham operation group and model group,The ALI model of sepsis was prepared by cecal ligation and puncture (CLP). In order to achieve the effect of experimental observation, the rats were killed after the operation 12 h, and the lung tissue HE staining analysis was performed, and the levels of MPO and MDA were observed. Results The degree of lung injury and the levels of MPO and MDA in the model group were significantly higher than those in the control group and the sham operation group (P < 0.01).Conclusion Rats with cecal ligation and puncture sepsis model can well simulate sepsis inflammatory response and oxidative stress.
