AIM: To study the effects of curcumin on TNF-alpha and TGF-beta1 in serum and lung tissue of SiO2-induced fibrosis in mice. METHODS: 75 mice were divided into five groups. After treated with curcumin 6 and 9 mice of each group were sacrificed on day 14 and 42 respectively to take their blood and lung tissue. The level of TNF-alpha and TGF-beta1 was observed by ELISA. RESULTS: The infection reaction of lung tissue and fibrosis in model group was obvious. Compared with sham operation group, TNF-alpha and TGF-beta1 in serum and lung tissue increased significantly(P<0.01), but decreased in different degrees after treated with curcumin(P<0.05). CONCLUSION: Curcumin can decrease the level of TNF-alpha and TGF-beta1 in serum and lung tissue of SiO2-induced fibrosis in mice and have the anti-fibrosis role by deregulating cytokine level.
