OBJECTIVE: To seek an effective drug for treatment of human hyperplastic scar through studying the effects of curcumin on fibroblast growth and collagen synthesis.

METHODS: Fibroblasts derived from scar tissue and from normal epidermal tissue were isolated and cultured separately with tissue-block method, their morphology were observed under invert phase contrast microscope, their growth curve was drawn respectively to determine the speed of growth. Then, fibroblasts from scar were stimulated with curcumin in different concentrations (0, 12.5, 25, 50 and 100 micromol/L) for detecting the inhibitory effect of curcumin on growth of fibroblasts using MTT methods and that on activity of precollagen alpha-1 gene transcription in fibroblast was detected by RT-PCR.

RESULTS: The cell growth curve showed that double-multiplying time was 5 days in fibroblasts from scar and 4 days in those from normal dermis, showing significant difference between them (P<0.05). MTT showed that curcumin in 12.5 micromol/L showed a cell proliferation enhancing trend, and its absorbance value was significantly higher than that in the normal group, but the effect turned to inhibition when concentration increased to over 25-100 micromol/L, and became significant inhibition at concentration of 50 and 100 micromol/L. Besides, curcumin also showed markedly inhibition on collagen type I synthesis in fibroblasts (P<0.01).

CONCLUSION: High concentration curcumin can inhibit effectively the fibroblast proliferation and collagen I synthesis in hyperplastic scar, therefore, may has therapeutic effect on the disease in human being.
