Abstract

Objectives : This study was performed to investigate the anti-fibrogenic effect of Injinchunggan-tang on cultured rat hepatic stellate cells. Materials and Methods : Hepatic stellate cells(HSC-T6) were treated with various concentrations of Injinchunggan-tang extract for 24, 48, and 72 hours. The extraction was done with distilled water. After the treatment, cell viability, proliferation, procollagen levels and the mRNA of the TIMP-1, TIMP-2, and ASMA were measured by using MTT assay. BrdU assay, procollagen type I C-peptide EIA kit and RT-PCR. Results : The proliferation, mRNA expression and synthesis of collagen of the hepatic stellate cells were inhibited by Injinchunggan-tang treatment in a dose-dependent manner. This indicates the prescription has inhibitory effect on fibrogenesis of the liver by regulating the fibrogenesis associated genes in transcription. Cell viability was inhibited in time- and dose-dependent manners. It seemed that the drug should be used with sufficient dose to acquire treatment effect. Conclusion : These results suggest that Injinchunggan-tang is beneficial in the treatment of cirrhotic patients as well as for the patients with chronic hepatitis.
