Moxibustion can significantly suppress the expression of TGF-beta1mRNA in the pulmonary tissue in the rat of bleomycin-induced pulmonary fibrosis. - GreenMedInfo Summary

OBJECTIVE: To explore the mechanism of moxibustion arresting the pulmonary fibrosis and provide experimental basis for prevention and treatment of pulmonary fibrosis with acupuncture and moxibustion. METHODS: One hundred and forty SD rats were randomly assigned to 4 groups: a blank group, a model group, a moxibustion group and a prednisone group, 35 rats in each group. The 3 groups expect the blank group were injected with bleomycin via trachea to induce experimental pulmonary fibrosis model, and 7 days after modeling, they were treated with moxibustion at bilateral Feishu (BL 13) and Gaohuang (BL 43), 3 cones each point, once each day, 10 days constituting one therapeutic course with an interval of one day between courses. After 3 courses, all rats were killed and expressions of TGF-beta1mRNA were detected with PCR method. RESULTS: The content of TGF-beta1mRNA in the pulmonary tissue in the moxibustion group and the prednisone group was significantly lower than the model group (P<0.01), and there was no significant difference between the moxibustion group and the prednisone group (P>0. 05). CONCLUSION: Both moxibustion at Feishu (BL 13) and Gaohuang (BL 43), and prednisone treatment can significantly suppress the expression of TGF-beta1mRNA in the pulmonary tissue in the rat of bleomycin-induced pulmonary fibrosis.
