Abstract:
Objective: To explore the protective effect of formula of Gougancai decoction (FGD) on acute liver injury induced by carbon tetrachloride (CCl4) in rats, in order to provide basis for the development of pharmaceutical preparations or healthcare products. Method: Sixty rats were randomly divided into normal group, Silymarin group (120 mg·kg-1) and FGD groups (475, 950, 1 900 mg·kg-1). The normal group and the model group were given equal volume of saline by gavage, while the other groups were administered with the corresponding dose of drugs according to the body weight. After 10 days, the acute liver injury model was established with 12% carbon tetrachloride peanut oil solution (5 mL·kg-1), except the normal group. All of the rats were put to death to collect serum and liver tissues. The contents of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), total bilirubin (TBIL), malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) were detected by biochemical methods, the levels of tumor necrosis factor-alpha (TNF-α), interleukin-1β (IL-1β) and interleukin-6 (IL-6) in liver tissues were determined by enzyme-linked immunosorbnent assay(ELISA). Nuclear factor-κB (NF-κB) and peroxisome proliferator-activated receptor-γ (PPAR-γ) protein expression in liver tissues were detected by Western blot, and htoxylin eosin (HE) staining was used to observe the variation of liver histopathological. Result: Compared with the normal group, the serum activities of AST, ALT, ALP and the content of TBIL, MDA in the model group were significantly increased (P<0.01), the levels of TNF-α, IL-1β, IL-6 in liver tissue were remarkably increased (P<0.01), but the serum activities of SOD, GSH-Px were significantly decreased (P<0.01), the expression of NF-κB was enhanced in liver tissue (P<0.01), and PPAR-γ was down-regulated (P<0.01), indicating the successful modeling of acute liver injury. Compared with the model group, FGD could reduce the activities of AST, ALT, ALP and the contents of TBIL, MDA (P<0.05, P<0.01), decease the level of TNF-α, IL-1β, IL-6 (P<0.05, P<0.01), and down-regulate the expression of NF-κB (P<0.05, P<0.01), but up-regulate the activities of SOD, GSH-Px and the expression of PPAR-γ (P<0.05, P<0.01). The liver tissue lesions were alleviated to varying degrees. Conclusion: FGD has a protective effect on CCl4-induced acute liver injury in rats, and its mechanism may be related to the activation of PPAR-γ and the inhibition of NF-κB signaling pathway, with anti-inflammatory and anti-oxidative effects.
