摘要
Objective: To investigate the effects of connective tissue growth factor(CTGF) and collagen type I(COL-I) on the pathogenesis of scleroderma and explore the relationship between the level of COL-I and CTGF. Methods: 12 mice model of scleroderma was established by the injection of Bleomycin. The level of CTGF and COL-I were detected by immunohistochemical method. The relationship was analyzed between CTGF and COL-I level. As control group, 12 healthy mice were selected. Results: The levels of CTGF and COL-I in sclerotic models were higher than in normal controls(P < 0.05). It was found that there was a correlation between the level of CTGF and COL-I. Conclusion: CTGF and COL-I played an important role in the hardening process of the skin lesions of the mice model, which may be involved in the pathogenesis of scleroderma.
