초록

Objectives : This study was performed to investigate the anti-fibrogenic effect of Angelica Gigantis Radix on cultured rat hepatic stellate cells. Materials and Methods : Hepatic stellate cells(HSC-T6) were treated with various concentrations of Angelica Gigantis Radix extract for both 24 and 48 hours. The extraction was done either with distilled water or 80% EtOH. After the treatment, cell viability, cell proliferation, procollagen production and the mRNA expression of the ASMA, TIMP1, TIMP2, procollagen Type 1a2, and Cytokine IL-6 production were measured by using MTT assay, BrdU assay, RT-PCR, procollagen Type I C-peptide EIA and IL-6 ELISA assay. Results : The cell viability treated with water extraction was significantly increased, but there were no significant changes treated with 80% EtOH extraction. The cell proliferation treated with water extraction decreased only in the 24 hours group, while there were significant decreases either in the 24 and 48 hours groups treated with 80% EtOH extraction. The mRNA expressions of the ASMA, TIMP2 and procollagen 1a2 decreased in a concentration-dependent manner in the 48 hours group. Procollagen production decreased in a concentration-dependent manner in both the 24 and 48 hours groups. Cytokine IL-6 production increased in a concentration-dependent manner in both the 24 and 48 hours groups. Conclusion : These results suggest that Angelica Gigantis Radix is beneficial in the treatment of cirrhotic patients as well as for patients with chronic hepatitis.
