Abstract:

OBJECTIVE: To investigate therapeutic effects of curcumin on hepatic fibrosis and the variation of correlated cytokine. METHODS: Rat models of hepatic fibrosis were made by carbon tetrachloride. Curcumin of 10, 20, 40 mg per 100 gram weight of rat were given to these rats of curcumin group respectively from ninth week. Normal, dissolvent, model and Salvia miltiorrhiza groups were made as controls. Serum levels of ALT, AST, HA, LN, PC-III were detected; Serum levels of TGF-beta1 and TNF-alpha were detected by ELISA method; Serum levels of NO were detected by chemical method. HE and Masson staining were conducted in hepatic tissues to observe pathological variations. Grades of hepatic fibrosis were evaluated according to SSS system. Immunohistochemical staining was executed for detecting PDGF-BB in liver, and professional software for image analysis was used. RESULTS: Curcumin could decrease serum levels of ALT, AST, HA, LN, PC-III obviously, P < 0.05, which were increased in fibrotic group. Curcumin could decrease cytokine levels of NO, TGF-beta1, TNF-alpha, P < 0.05. Curcumin could obviously improve liver pathological variations of fibrotic rats. The score of hepatic fibrosis in curcumin group reduced significantly, P < 0.05. Curcumin treatment could reduce the expression of PDGF-BB, P < 0.05. These effects were dose-dependent. CONCLUSION: Curcumin can heal rat hepatic fibrosis. Effects of reducing the expression of correlated cytokines may be mechanisms of therapeutic effects of curcumin on hepatic fibrosis.
