Abstract：Objective To establish an animal model of SM by equal toxicity dose(1LD50)-induced acute pulmonary injury in rats and compare the differences of inflammatory factor and protein expression. Methods Rats were randomly divided into five groups. ELISA and immunohistochemical methods were measured. Results Serum INF-γ and IL-23 levels in the intraperitoneal SM group were increased compared with the tracheal SM group;there were also significant differences in serum IL-4 levels between the two groups. In the alveolar septum , the positive expression ratios of NF-Kβ1,NF-Kβp65,ERK,JNK,and p38MAPK in the intraperitoneal SM group were increased compared with the tracheal SM group. Conclusion Using SM (1LD50),There are significantly higher serum inflammatory factor levels and protein-related expression in the alveolar septum of rats intraperitoneally injected with SM compared with those administered SM by intratracheal instillation. The results suggest that pulmonary inflammatory reactions associated with SM are dependent on the route of exposure.
