Peng XD, Dai LL, Huang CQ, He CM, Yang B, Chen LJ: Relationship between anti-fibrotic effect of Panax notoginseng saponins and serum cytokines in rat hepatic fibrosis. Biochem Biophys Res Commun. 2009 Oct 9;388(1):31-4. Epub 2009 Jul 24.
The aim of this study was to investigate the relationship between anti-fibrotic effect of Panax notoginseng saponins (PNS) and serum cytokines in rat hepatic fibrosis. Hepatic fibrosis induced by carbon tetrachloride (CCl (4)) was studied in animal models using SD rats. Liver index, serum alanine amino transferase (ALT), aspartate amino transferase (AST), transforming growth factor-beta1 (TGF-beta1), tumour necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6) and interleukin-10 (IL-10) were measured, respectively. Liver index and the degree of liver fibrosis were also determined. Our results showed that the levels of ALT, AST and liver index in PNS-treated group were markedly lower than those in model group. PNS therapy also significantly attenuated the degree of hepatic fibrosis, collagen area and collagen area percent in liver tissue. Furthermore, the levels of serum TGF-beta1, TNF-alpha and IL-6 were strikingly reduced in PNS-treated group compared with model group while the production of IL-10 was up-regulated. These findings demonstrate that PNS has certain therapeutic effects on hepatic fibrosis probably by immunoregulating the imbalance between pro-fibrotic and anti-fibrotic cytokines. |
