  • Objective: The aim of this study is to investigate the effect of Injin butanol fractions with Thin Layer Chromatography on Fas-mediated Apoptosis. Method: Injin-butanol fraction separated by TLC. MIT assay, cell cycle analysis, Caspase-3 protease assay, DNA fragmentation assay and quantitative RT-PCR were performed to evaluate the effects of TLC extraction of lnjin-butanol fraction on cell viability, cell cycle progression and apoptosis. Results: Scopoletin, luteolin, apigenin and unknown powder was isolated by TLC. Fas-mediated apoptosis analysis shows that scopoletin has inhibiting function on apoptosis. Caspase- 3 protease assay analysis shows that scopoletin inhibits activity of caspase-3. Quantitative RT-PCR analysis shows that no activity on caspase-3, but apoptosis inhibition cytokine -Bcl-2- is activated, and apoptosis activating cytokine -Bax- is unactivated. Conclusion: These results show that each fraction of Injin-butanol TLC extraction, especially scopoletin, acts as a protective function on liver cell viability, and inhibitory function on apoptosis.

  • Objective : The aim of this study is to investigate the effect of Injin fractions on hepatic fibrosis induced by $TGF-{\beta}1$. Method : $TGF-{\beta}1$ mRNA, protein, $TGF-{\beta}1$ receptor, Smad family and PAI-I mRNA were studied in HepG2 cell, and the proliferation, connective tissue growth factor, fibronectin and collagen type I mRNA in T3891 fibroblast by quantitative RT-PCR, ELISA and thymidine incorporation assay. Results : On $TGF-{\beta}1$ mRNA and protein synthesis in HepG2, $H_2O$, butanol and hexane fractions of Injin showed inhibitory effect in a dose-dependent way. In the study on $TGF-{\beta}1$ receptor, Smad family and PAI-1 mRNA in HepG2, $H_2O$, butanol and hexane fraction of Injin showed inhibitory effect on the expression of PAI-1 in a dose-dependent way. On the proliferation of T3891 fibroblast induced by $TGF-{\beta}1$, $H_2O$, ethylacetate and butanol fractions of Injin showed inhibitory effect. In the study on the factors affected by $TGF-{\beta}1$, $H_2O$, ethylacetate and butanol fractions of Injin showed inhibitory effect on CTGF, and $H_2O$, butanol, chloroform and hexane fractions showed inhibitory effect on the expression of collagen type I, whereas no fraction showed inhibitory effect on the expression of fibronectin Conclusion : These results show that each fraction of Injin acts as a fibrosis inhibitory factor by itself or in combination, ultimately inhibiting liver cirrhosis.
