ABSTRACT
Objective:
To observe the role of lamividine and silymarin preventing and curing liver fibrosisrelevant factors induced by alcohol drinking in hepatitis B virus (HBV) transgenic mice (Tg mice).Methods:
Forty HBV-Tg BALB/C mice with 1.3 copy were randomly divided into 4 groupsa control group,a model group,a lamivudine group and a silymarin group.Tg mice in control group were treated with normal saline via intragastric administration;Tg-mice in the model group were treated with 50% alcohol (5 mL/kg) once a day via intragastric administration;while Tg-mice in lamivudine group and silymarin group were treated with alcohol (5 mL/kg) plus laminvudine (100 mg/kg) and silymarin (200 mg/kg) once a day via intragastric administration respectively.All groups were raised for 10 weeks.The levels of HBV-DNA copy number,ALT,AST in serum,the degree of inflammation,the degree of fibrosis,the mRNA expression levels of TGF-β 1,Smad3,Smad7 and connective tissue growth factor (CTGF),and the protein expression levels of TGF-β1,CTGF and α-SMA in liver tissue were detected.All the images were scanned with electronic computer and the data were analyzed with SPSS13.0 software.Results:
Compared with the control group,liver injury were significantly aggravated,while HBVDNA copies,mRNA levels ofTGF-β1,Smad3,Smad7 and CTGF as well as the protein levels of TGF-β1,CTGF and α-SMA were significantly increased (P<0.05).Compared with the model group,liver injury were significantly attenuated in silymarine group and lamivudine group,while mRNA levels of TGF-β 1,Smad3 and CTGF as well as the protein levels of TGF-β1,CTGF and α-SMA were significantly decreased;mRNA level of Smad7 was further increased (P<0.05);the levels of ALT and AST in serum were decreased in the silymarine group (P<0.05).Conclusion:
Lamivudine and silymarin relieve the histological damage in the liver of alcohol-fed Tg mice.The mechanisms for the beneficial effects of lamivudine or silymarin might be related to inhibiting the expression of TGF-β 1,Smad3 and CTGF,modulating the expression of Smads and suppressing the activation of HSC.
