Objective To investigate Enalapril and Valsartan on liver in experimental fibrotic rats, by observing its effects on the expressions of TGFβ1, Smad3 and CTGF. Methods A total of 52 male wistar rats were randomly divided into two groups:the control group (n=16), the model group (n=36). In the model group, all rats were given subcutaneous injections of 40%CCl4 once every three days. Rats in the control group were given subcutaneous injections of oil. When the hepatic fibrosis models success 60 days later, 20 rats selected randomly from the model group were given Enalapril or Valsartan until 75 days by gastric gavage. Histopathological study of the liver tissues was done with HE and Masson staining. Expression of TGFβ1, Smad3 and CTGF protein was detected by western blotting. The mRNA expressions of Smad3 and CTGF were examined by Real-time PCR. Results Enalapril and Valsartan attenuated the degree of hepatic fibrosis. TGFβ1 mRNA expression level (2.77±0.83, 2.97±0.48 vs. 4.07±0.97, P<0.05) and protein expression level (0.51±0.10, 0.49±0.11 vs. 0.60±0.09, P<0.05), Smad3 mRNA expression level (4.15±0.98, 4.17±0.98 vs. 6.06±0.85, P<0.05)and protein expression level (0.72±0.09, 0.69±0.07 vs. 0.98±0.13, P<0.05), CTGF mRNA expression level (5.82±1.21, 5.34±1.24 vs. 7.63±1.25, P<0.05) and protein expression level (0.51±0.05, 0.47±0.13 vs. 0.61±0.05, P<0.05) were reduced by Enalapril and Valsartan. Conclusion Enalapril and Valsartan can delay the progression of hepatic fibrosis.
