Comparative study on pulmonary fibrosis model induced by Bleomycin in three strains of mice
摘要
Abstract
Objective To find out the most proper model of human pulmonary fibrosis through a comparative study of pulmonary fibrosis in three strains of mice induced by Bleomycin (BLM). Methods C57BL/6, BALB/c and KM mice were randomly divided into model groups and normal control groups, respectively. Three model groups received a single intratracheal instillation of 5 mg/kg body weight of BLM to induce pulmonary fibrosis, while normal control groups were administrated the same amount of normal saline. On the 7th, 14th and 28th day, 8 mice were respectively sacrificed in each model group. Lung tissues were removed to measure the lung coefficient and hydroxyproline content of the mice at different time points, and Masson staining was used to evaluate the extent of pulmonary fibrosis. Results The lung coefficient, hydroxyproline content and pulmonary histopathological changes of each model group were remarkably different from those of the corresponding normal control group (P < 0.05). Compared with the BALB/c and KM model groups, the lung coefficient, hydroxyproline content and pulmonary histopathological changes of the C57BL/6 model group were significantly increased (P <0.05). Conclusions C57BL/6 is more suitable for the model of pulmonary fibrosis in the three strains of mice because of sensitive Bleomycin reaction and obvious pulmonary fibrosis. Of the three strains, C57BL/6 is the most suitable model in studying pulmonary fibrosis.关键词
